Mini “tanks” step into duct air conditioning for cleaning work

  One-foot-square box, two swivel webcam, at the foot of “push off” with two tracks, the small “tanks” look like small robots that are dedicated to clean central air conditioning. Yesterday, two small “tanks” Carrefour South third ring shops started opening soon central air conditioner for a three-day “bath”.

Carrefour South third ring road store has been completed, and before the end of the opening Welcome, in accordance with the relevant requirements, large supermarket opened to a centralized before cleaning, clearing the construction waste generated in the course of construction, yesterday, Carrefour South third ring road store cleaning central air “heavy responsibility” falls on two small “tanks” on the body.

9th when the morning came to Carrefour, Central fresh company workers are a small “tanks” placed in a duct, then the negative pressure machines have also been installed in the wind on a level crossing, the small “tanks” who monitors connections and worker around the camera well, everything’s in place, the small “tanks” with a big brush work.

Seen from the monitor to, large brush began to WHIR, each sweeping a Department worker on command the camera this way and that visits, to see where there is no sweep, immediately directed the small “tanks” run to sweep up. This small “tanks” “swish swish” sweep, side wind crossing the negative pressure machines “WHIR” smoking and in a short time, more than 20 metres long duct cleaning, reporter asked the workers to open the trash, just more than 20 meters long tunnel has been swept out of the lime sludge and other construction debris, is 342.

“This is just the completion of construction, central air conditioning in the dirt is still relatively simple. “Jin Shiyou central air conditioning clean industry company Chairman Huang Jingyue told reporters that if used architecture, central air conditioning in the dirt” variety “. RJ047

Expert view

Air conditioning cleaning on a regular basis far more power

In accordance with the relevant provisions of public buildings once every two years to central air conditioning clean, but nearly 20,000 public buildings in Beijing, do central air conditioning clean less than 3,000. “Central air conditioner cleaning time you need to spend a hundred thousand of dollars, but the ‘ wash ‘ after air conditioning efficiency can save electricity 5% to 8%. “Wang Dongzhan international trade construction industry branch of China building clean-Commission Secretary-General, told reporters that cleaning fee that a hundred thousand of dollars to spread on the floor area, only 4 Yuan per square meter or so; but at least tens of thousands of square meters of public buildings, central air conditioning uses electricity has a hundred thousand of Yuan a year, regular cleaning of air-conditioning electricity savings of at least tens of thousands of dollars a year.

General Knowledge on “Stainless Steel Coil Heat Exchanger for dutch tub,Wood fired hot tub heater coils ”

principle Wood-Fired-Hot-Tub-workingThe Firehot Coil Heat Exchanger works depending on the principle of natural hot circulation.  Natural hot circulation refers to: in a closed system,depending on density difference between hot and cold water,to form circulating liquid to drive an energy transmission. In the dutch tub coils,the cold water flows in from the bottom tail pipe,and goes up in form of spiral state,during this process,absorbing fire heat to let the water inside gradually become hot,and finally flows into the tub.During this cycle,the water in the tub becomes more and more hot…For DIY your own outdoor hot tub,please refer to this article.

The wood fired Hot Tub,used as hot tub heat exchanger, was just to utilize the Coil Heat Exchanger works depending on the principe of natural circulation to warm water to have a bath.

Without electricity or gas, you can enjoy bathing in a Wood-Fired Hot Tub in free and relax yourself at most.

This simplicity still appeals to many people. But also the rituals around it, like gathering the wood, burning the wood, regulating the stove and the heat, mixing the water up front. And then enjoy the rising steam and noises from the heater…….

In that respect a Wood fired Hot Tub is a total different product compared with the Jacuzzi from today which is working on electricity.

What is a Wood fired Hot Tub? A Hot Tub generally consists of the following components:

A heater / stove (made of stainless steel) being a sort of metal container below the water in which you can burn the wood. This heater has 2 openings that are above the water, 1 for air and landing with a wooden lid with wooden handle, and 1 for smoke exhaust. All our stoves are made of 2-3 mm stainless steel.

A chimney connected to the air pipe of the stove. This is a long metal pipe with a cap that serves as a spark arrestor.

A protective panel around the stove protecting you from burning on a hot stove.

Benches all around, so you can sit and relax. On request benches are removable for cleaning purposes.

Drink holders depending on the model attached to the cap of the stove, sometimes attached to the exterior. You can keep your drink or snack at a place holder.

A ladder, to be able to take place in the wooden bathtub.

A lockable wooden lid, Wood-Fired Hot Tub at the end when you can not use it. This prevents such leaves may fall, or insects get in the water.dutchtub-works

A stop so you can dirty water drains and evt. aanluitmogelijkheid one can achieve in the stormwater or sewer for dirty water.

Stainless steel around the Wood-Fired Hot Tub. This stainless steel straps are the rings around the Tobbe Tobbe which you can sue. Suppose that Tobbe has shrunk slightly in dry weather, you can tighten the straps slightly. On the stove side you can usually tighten the straps.

General Knowledge on “Air Conditioner Temperature Sensor”

Air conditioner temperature sensor is a negative temperature coefficient thermistor, referred to as NTC, its resistance decreases with increasing temperature, and increases with decreasing temperature. Resistance at 25 ℃ for nominal value. NTC common failure for resistance becomes large, open, damp mildew resistance changes, short circuit, plug and seat a bad contact or leakage, etc., caused by air conditioning air conditioning failure caused by abnormal terminal voltage detection CPU’s. Conditioned common indoor ambient temperature NTC NTC, indoor coil NTC, NTC and other three outdoor coil, more upscale air conditioning also apply outside ambient temperature NTC, compressor suction, exhaust, etc. NTC.

NTC in the circuit, there are two ways:
A temperature change so that the change in resistance NTC, CPU also changes the voltage of the terminal, CPU determines in accordance with a change in voltage of the air conditioner operating state. Ambient room temperature NTC effect: NTC ambient room temperature according to the set of working conditions, indoor environment temperature detection or automatic start-stop frequency. Fixed-frequency air temperature difference between the indoor temperature range for the set value + 1 ℃, that is, if the cooling set 24 ℃, when the temperature drops to 23 ℃ compressor stops, when the temperature rose to 25 ℃ compressor; if the heating set When given 24 ℃, when the temperature rose to 25 ℃ compressor stops, when the temperature dropped to 23 ℃ compressor. Worthy of note is the temperature setting range is usually between 15-30 ℃, so the ambient temperature is below 15 ℃ refrigeration does not work, the heating temperature above 30 ℃ ambient temperature does not work. Inverter air conditioner according to the set temperature and the room temperature difference frequency control, the higher the greater the difference between the operating frequency of the compressor, so soon after the compressor start speed increase. Indoor coil NTC: indoor coil control cold too cold (below + 3 ℃) protection detection, cooling the lack of fluoride detection; anti-cold wind blowing heating, thermal protection testing. Air conditioning and refrigeration 30 minutes to automatically check the indoor coil temperature reach 20 ℃ cool if the automatic diagnosis and the lack of fluoride protection. Ruoyin some reason the indoor coil temperature drops below + 3 ℃ to prevent frost also shut down (too cold) heating the indoor coil temperature is below 32 ℃ within the fan does hair (anti-cold), higher than 52 ℃ outside the fan stops, higher than 58 ℃ compressor stall (overheating); some air conditioning and heating in the automatic control of fan speed, and some air conditioning automatically switches electric auxiliary heat, inverter air speed. Outdoor coil NTC: temperature detection defrost heating, refrigeration condensing temperature detection. Heating heat pump defrost is an important feature, the first frost of CPU timing (usually 50 minutes), after the frost from outdoor coil NTC control (typically -11 ℃ To defrost, + 9 ℃ then heating). Refrigeration condensing temperature of 68 ℃ stop compressors, high pressure switch instead of the role of the reduced frequency inverter cooling coil prevent continue to heat up. Outdoor ambient temperature outside NTC control fan speed, winter warm-up compressors exhaust NTC: make frequency machine down to avoid overheating the outside, the lack of fluoride detection inspiration NTC: controlling the flow of refrigerant, stepping motor control section valve to achieve.

Failure analysis of indoor and outdoor coil:NTC highest failure rate, failure is also a wide range of phenomena. Indoor and outdoor coil temperature at NTC due to the changing position and condensation or high environment, so the failure rate is relatively high. Mainly in the power supply is normal and the machine does not work, the work of a short stop, the fan is not running out of the machine within the normal heating, the fan does not work outside or abnormal shutdown, the compressor does not start, poor frequency, frequency does not work, heating no frost and so on. Defrosting faults can substitute the outdoor coil defrost board NTC or outdoor. NTC also check the room ambient temperature when the power supply and air conditioning does not work properly. Working non-stop air conditioning or reach the set temperature down, it must first check the ambient room temperature NTC, inverter air conditioner is not working properly and it will be relevant. If a problem occurs due to the ambient room temperature NTC will make the CPU misjudged the ambient room temperature and cause malfunction. 1. The room ambient temperature sensor resistance becomes larger, causing frequent air conditioner starts. 2. indoor pipe temperature sensor resistance decreases, causing the machine to start shortly protection. 3. The ambient room temperature, pipe temperature thermal properties change, causing malfunction 4. Indoor air conditioning duct temperature change is 0Ω, resulting in the whole remote boot no reaction 5. air conditioning failure, in addition to the work that satisfies CPU + 5V power reset clock oscillation, but also to measure the power, voltage, current is up and running properly, the detection of the sensor is also very important.

Start capacitor: to start the single-phase AC induction motor electrolytic capacitor or polypropylene, polyester capacitors.

Principle of start capacitor

Single-phase single-phase flow through the motor current can not generate a rotating magnetic field, the need for capacitors for phase separation, the purpose is to make the two winding current generated near a phase difference of 90 °, to produce a rotating magnetic field.

Capacitive induction motor has two windings, namely start winding and run winding. The two windings 90 degrees in space. On the start winding in series with a large capacitance, when running winding and start winding through the single-phase AC power, the role of the capacitor so that the start winding current in the current time than running ahead of the winding angle of 90 degrees, the first arrival maximum. Forming two identical magnetic field pulses in time and space, so that the air gap between the stator and the rotor produces a rotating magnetic field, under the action of the rotating magnetic field, induced current, rotor current and the rotating magnetic field generated in the interaction electromagnetic torque, the motor spin.

For single-phase motor can be automatically rotated up, we can add a start winding in the stator, the start winding and the main winding 90 degrees in the space, the start winding connected in series to a suitable capacitor, so that the current in the primary winding approximately 90 degrees in phase, i.e. a so-called phase separation principle. Such two phase difference of 90 degrees in electrical flow into two temporally different by 90 degrees in the winding space, will produce (two-phase) the rotating magnetic field in space. In this rotating magnetic field, the rotor will automatically start, after starting, until a certain speed rise when mounted on the rotor by means of a centrifugal switch or other automatic control means the start winding is disconnected, and only the main winding during normal operation the work. So, start winding can be made short work. But there is a lot of time, start winding is not disconnected, we call this motor capacitive single-phase motor, steering motor to change this, by changing the position of a capacitor connected in series to achieve.

Start capacitor is calculated

Single-phase motor running capacitor is calculated: C = 1950I / Ucos∮ (microfarads)

Where:

I: motor current, U: supply voltage; cos∮: power factor, taking 0.75,1950: Constant

Starting capacitors are generally run by 1-4 times the capacitance calculation

Air Conditioner Synchronous Motor

Item: Air Conditioner Synchronous Motor

Short description: A synchronous electric motor is an AC motor in which, at steady state,the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field of any AC motor. A synchronous motor is only considered doubly-fed if is supplied with independently excited multiphase AC electromagnets on both the rotor and stator.Also named Air conditioner indoor gear fan.It is a small fan motor to works air conditioner outlet,let plastic leaf baffle to move and swirl.12V DC driven.

General Knowledge on “Air Conditioner Synchronous Motor”
  • Several reasons for the failure of Air conditioner pendulum synchronous motorFor the failure of the stepping motor of the air conditioner, there are generally two situations. One case is that the stepping motor is faulty, which causes the airflow flap of the air conditioner to fail to operate normally. The second situation is caused by man-made. After the air conditioner is turned on, the position of the swinging blade is artificially shaken, causing the pendulum blade to not close normally after being turned off. In this case, the power plug of the air conditioner can be unplugged and then plugged in again to resume normal procedures.

General Knowledge on “Contactor Coil”

In electrical engineering, because the quick disconnect AC and DC main circuit and frequently making and high-current control (some typed up to 800 amps) device circuit, so often applied to the motor as the control object can also be used to control plant equipment ﹑ ﹑ heater workhorses and every power units and other electrical loads, contactors can not only be switched on and off the circuit, but also has low voltage release protection. Contactor control large capacity, suitable for frequent operation and remote control. It is one of the important components of the automatic control system. In industrial electrical, the contactor many models, ranging from current 5A-1000A, which is quite extensive use.
AC contactor is opened and closed by the main circuit contacts, with auxiliary contacts to turn the control loop. The main contacts are normally open contacts, and often two pairs of auxiliary contacts normally open contacts and normally closed contacts, the contacts are often small as an intermediate relay with the main circuit. AC contactor contacts made from silver tungsten alloy with good electrical conductivity and high temperature ablative. AC contactor power moves from the AC magnetic field generated by the coil through the core band, electromagnet core consists of two “mountain” shape the young quartet built silicon, one of the fixed iron core, a coil, a variety of operating voltage selection. In order to make the magnetic stability, core plus side pull short-circuit loop. AC contactor after the loss of power, relying on spring return. The other half is the active core, constructed and fixed core to drive the main contacts and auxiliary contacts are closed off. More than 20 amps interrupter contacts plus a cover, using electromagnetic force generated when the circuit is opened, quickly pull off the arc and protect joints. Exposure apparatus can be high frequency operation, when the power is turned on and off as a control, the maximum operating frequency of up to 1,200 times per hour. Contactor life is high, often amounting to millions of mechanical life to ten million times, electrical life in general, compared with hundreds of thousands to several million times.

Technological development
AC contactor production as a whole, appearance and performance is improving, but the function remains unchanged. Whether and to what extent the development of technology, the ordinary AC contactor still has its importance. Air electromagnetic contactor Magnetic contactor (English: Magnetic Contactor) mainly by the contacts system, the electromagnetic actuator system, frame, auxiliary contacts and the shell (or chassis) components. Because the AC magnetic contactor coil generally use AC power supply, after excitation in the contacts, usually say “slightly” high-decibel noise, which is characteristic of electromagnetic contactor. After 80 years, the national research contactor solenoid silent and energy-saving, one basic feasible solution is to step-down after the AC transformer, then by the internal power supply into DC power rectifier, but the complexity of control and rare. Vacuum contactor vacuum contactor contact system is a vacuum chamber degaussing contactor. Semiconductor Contactor semiconductor contactor is a contactor accomplished by changing the current operation circuit loop conductive state and the off state. Permanent magnet permanent magnet AC contactor contacts is the use of magnetic repulsion of the same principle that opposites attract, and the formation of permanent magnet drive mechanism to replace the traditional magnet drive mechanism of a micro-power contacts.

How to check if the contactor coil in air conditioner good or not?

Check the voltage across the coil. If there is voltage but contactor did not pull the contactor,then can know it is damaged; if there is not voltage,then check the circuit board.
