Household air conditioning open 24 hours a day, it's about how much electricity
- Therefore, cannot be accurately how much electricity 24 hours every day.s
Air conditioning heating principle is what?
- Household air conditioning heating, the refrigerant compressor pressurized, outdoor to become a high temperature and high pressure gas, into the indoor machine heat exchanger (condenser) at this time, condensing liquid exothermic, become liquid, will heat the indoor air at the same time, so as to achieve the ultimate goal of improving indoor temperature. And reduced pressure liquid refrigerant through the throttle device, into the outdoor heat exchanger (evaporator) at this time, evaporation vaporization heat absorption, become gas, at the same time absorb the quantity of heat of outdoor air, outdoor air become more cold). Become a gas refrigerant entering the compressor start again the next cycle. It is a process based on the above, the realization of the heating and air conditioning.s
What is the difference between the central air conditioning and ordinary air conditioning?
- Simple to understand is the common air conditioning is a host to an indoor machine, central air conditioning is a host to tow the indoor machine of more than two (2).s
Air conditioning indoor machine drop
- There are three possible. 1) installation is unreasonable, the outlet of the household air conditioning is on the right, the right should be slightly higher than the left so the indoor machine (careful observation to the naked eye can see) 2) as a second-hand machine, so do not rule out drain the dirty blocking phenomenon, but there is not completely closed, because of the humidity of the air big or long running, condensate drainage result in birdbath overflow water not in time. 3) air conditioning sink for their own problems, such as cracks, etc. Lack of refrigerant, and, of course, the system freezes evaporator frosting line into leakage phenomenons
Outside air conditioning machine how to cleaning?
- Don't have to own washing, are now manufacturers to maintain.How does cleaning air conditioning does Regular cleaning air conditioning cleaning air conditioning, mainly is the panel and strainer mesh. Then, actually how to operation to achieve the best cleaning effect? Gome electrical appliances maintenance personnel puts forward several opinions: 1. According to the instruction manual remove strainer mesh first, remove the note don't touching the metal part of the indoor unit, prevent the scratch. 2. Remove the air strainer mesh, gently pat or use electric vacuum cleaner dust removal. If the strainer mesh dust too much, can rinse with water or soft brush dips in neutral detergent to clean, but not more than 50 ℃ above, when cleaning water temperature can't use washing powder, detergent, gasoline, banana oil, etc., in order to avoid the strainer mesh deformation. In addition, don't use a sponge cleaning, otherwise it will damage the strainer mesh surface. 3. Rinse off with clear water, dry with a soft cloth or blow dry, put the shade never exposure in the sun or the fire flame and drying, lest the strainer mesh deformation. 4. Clean the panel, with a soft cloth dipped in warm water or neutral detergent to wipe gently, and then with dry soft cloth to wipe dry.s
The development history of air conditioning
- In 1902, Dr Carrier invented the world's first air conditioner, is the industry regarded as "the father of air conditioning" and "expert", etc.s
The snow kind of what kind of air conditioning, they each have what effect
- The snow kind of classified as: 1, domestic now is the most commonly used freon R22. 2, new environmental protection refrigerant R410a refrigerant, everything, R407c, etc. The role of the snow kind of: Snow also called freon, freon will gas compressor for high temperature and high pressure liquid freon compression, and then sent to the condenser (seg) become normal temperature high pressure liquid freon after cooling, so the blow out outdoor hot air. And then to the capillary, into the evaporator (indoor machine), because the freon from capillary to evaporator space suddenly increases, pressure decreases, and liquid freon will China gas, into a gaseous cryogenic freon, to absorb a lot of heat, the evaporator will become cold, indoor machine of the fan will indoor air blows from the evaporator, so indoor machine out of the cold wind is blowing; Water vapor in the air is cooled after the evaporator will turn into water droplets, along the conduit flow, this is the reason why air conditioning will be out of the water. Then gaseous freon to go back to the compressor compression, continue to cycle.s
What is the difference between air conditioning and air source heat pump, with what principle?
- The scope of the air conditioning is very big, he included the air source heat pump. Air conditioners are divided into: evaporative and absorption. Air conditioning need refrigerant, only to the nature of the refrigerant evaporative often use cold media: R22, R407C, R410a, R134a has a and so on. Absorption often use cold media is: lithium bromide aqueous solution, etc General in refrigeration and air conditioning, it is through the phase change of refrigerant in the evaporator (liquid into gas) absorb indoor quantity of heat, again through the outdoor condenser heat to realize the refrigeration. His is mainly finned heat exchanger heat exchange equipment. And he is in the air air source heat pump low grade can be converted into we can use the high grade. Through the phase change of refrigerant in the evaporator (heat) to absorb heat from the air, and then through the interior of the condenser (or casing heat exchanger), heat release and heat taken from the implementation. This is his state of heating, refrigeration and its general air conditioning, just heat exchanger may be different, often use water as air source heat pump heating medium, through the casing heat exchanger of heat exchange. General air conditioning is ordinary finned heat exchanger. So the air source heat pump used, that is, the principle of air conditioning. At present domestic air source heat pump is more, very miscellaneous, do good giant is not much said, the recent finney is fines
