Air conditioning air conditioner (room air conditioner), suspension type AC is a region of space (normally closed) for handling air unit. It is the function of the room (or enclosed spaces, regional) cleanliness of air temperature, humidity, and air velocity and other parameters be adjusted to satisfy human comfort or process requirements. Works  hung air conditioning compressors the gaseous refrigerant is compressed for high temperature and high pressure liquid refrigerant, and then sent to the condenser (outside unit) after cooling at ambient temperature and high pressure liquid refrigerant, so the outdoor unit is blowing out hot air. Then to capillary, entered evaporator (indoor machine), due to refrigeration agent from capillary arrived evaporator Hou space suddenly increases, pressure reduces, liquid of refrigeration agent on will vaporization, into gaseous cryogenic of refrigeration agent, thereby absorption large of heat, evaporator on will changed cold, indoor machine of fan will indoor of air from evaporator in the blowing had, so indoor machine blowing out of is cold; air in the of steam encountered cold of evaporator Hou on will condensation into drops, along pipes stream out, this is air conditioning will water of causes. Then continue to compress the refrigerant back to the compressor in gaseous, continuing to loop. When heating uses a four-way valve parts, the direction of flow of the refrigerant in the condenser and evaporator and cooling time, therefore when outdoor heat is blowing cold air, the indoor unit is blowing hot air. Is liquefaction in junior high school physics learning (from gas to liquid) to be discharged when the heat and evaporation (from liquid to gas) to absorb heat when works. Air conditioning function 1, cooling In the design and manufacture of air conditioners, generally allow temperature control between 16~32℃. If the temperature setting is too low, add unnecessary power consumption on the one hand, caused when a large temperature difference between indoor and outdoor on the other hand, people in and out of the room cannot quickly adapt to variations in temperature, easy to catch cold. 2, dehumidification During the process of cooling with dehumidification of air conditioners. People feel comfortable relative humidity should be at about 40~60%, when the relative humidity is too large, such as 90%, even if the temperature within the comfort zone, the impression remains poor. 3, heating Heat pump type air conditioner with electric heat up function. Outdoor environmental temperature drops progressively smaller warming ability, if temperatures ranging from-5 ° c can hardly meet the heating requirements. 4, purify air Containing a certain amount of harmful gases in the air such as NH3, SO2, etc, as well as all kinds of sweat, body odor and the bathrooms stink, stench. Air conditioner cleaning methods are: move to fresh air, filter and Photocatalyst using activated carbon adsorption and absorption, and so on. A, for fresh air using fan system drain the Interior moist air toward the outdoor, indoor form a certain degree of negative pressure, fresh air from around the door, the window seam into the rooms, improved indoor air quality. B, light catalyst: light exposure can be regenerated adsorption (collection), nicotine, ammonia release harmful substances such as acetic acid, hydrogen sulfide, and reusable. 5, increasing air anion concentration Size the charged particles in the air, harmful to human comfort.  Air negative ion generator to increase installed on Aero-anion concentration, making the environment more comfortable, while lowering blood pressure, suppress asthma have some medical benefits. Significance of air conditioning nameplates such as model: KFR-26GW K: representatives of household air conditioner F: split air conditioning (c: on behalf of window-type air conditioning) R: the heat pump heating function (no r represents the form cold air conditioning, d for auxiliary heating function) 26: this figure represents the rated cooling capacity G: wall mounted air conditioning (l on behalf of floor-standing air conditioner, which is commonly referred to as cabinet) W: split outdoor unit Energy efficiency ratio: 2.99 Energy efficiency ratio is the ratio of rated power and rated cooling capacity, bigger is better. Current state regulations of household air conditioner EER 2.6-3.4, is divided into five levels, levels are the best, that is, energy efficiency ratio at 3.24-3.4 per cent belong to the level of the most energy-efficient air conditioning products. Rated cooling capacity: 2700W We usually say about 2200W-2600W 1 HP rated cooling capacity of air conditioning or so. Rated heat: 3000W (3600W) Rated number of Gevas, in brackets indicates maximum number of Gevas. Rated power: cooling 903W Heating 920W (1520W) This is what we usually call a power consumption, kW/hour. Heating power is indicated in brackets the maximum rated power, which means that a hot hour of maximum power consumption is around 1.5. Overall dimensions: (indoor/outdoor) (mm) w x h x d Air conditioner indoor unit and outdoor unit size, usually expressed in millimeters, members before buying the best measurement of indoor and outdoor installation location is correct. Quality: indoor 12kg/outdoor 35kg Air conditioning inside and outside NET, usually representatives of air conditioning a little bit heavier material used is relatively. Operation noise: Indoor unit: low-luxury: 26-35db Outdoor unit: less than or equal to 51db Air conditioning noise value most currently on the market were within national standards, some may be relatively low frequency noise of value. Air conditioning installation specifications or not, as well as for maintenance cleaning the noise has a number of implications. Application area: 12-18 square meters This is the factory’s air conditioning reference application area, we may, under normal room 115W-145W, living room 145W-175W parameters for calculations on your own. Not enough to avoid a cooling effect, or caused by excessive waste. Circulating air volume: 420 sqm/h This means that within an hour, air conditioning air distribution area size. Often in the case of similarly rated cooling capacity, vertical Cabinet confidential than some wall-mounted air conditioning recirculated air. Buy air buy installed household central air conditioning installed in 5 steps Step one: determine host model First of all to consider the housing area and toward, and see if there is a large area of window to calculate the simultaneity usage coefficient of air conditioning maximum. In General, the normal home environment, is often not the actual need to use cold whole House cooling capacity and integrated, but lower than the latter, the former about needs to 60% 70% then the latter. This saves investment, avoiding unnecessary waste. Rooms are actually required cooling capacity can be calculated by the following formula: Real cold area = housing floor space x efficiency rate of x65% of housing (except uncooled areas such as kitchen, bathroom) Actual cold cold = area x the actual unit cooling capacity Step two: determine if indoor unit air outlet Based on the chilling requirement of actual size model, each room or Office requires only one indoor unit or air outlet, if the area of the living room is large, or rectangular, can add one more indoor unit or air outlet. For every 12 square takes about one subject. Step three: determine the layout, air conditioning: 1, host location with good to pay attention to ventilation, ease of maintenance, and hidden as much as possible and avoid affecting House indoor look and noise; 2, the position of the indoor unit to work with the interior layout, usually hidden in the ceiling, or hidden at the top of high cabinets. General indoor unit is super thin, it takes only around 25 cm in height can be placed. Return air installation should pay attention to good indoor air form a cycle, to ensure that the effect of air conditioning and air quality.
