Detachable air conditioner
The utility model belongs to ground source heat pump type air-conditioning equipment field, is specifically related to a kind of detachable air conditioner.
Air-conditioning, be a class while utilizing refrigerant air-liquid to transform suction/heat release change the device of environment temperature.Current common domestic air conditioning cold-producing medium used is freon, its operation principle is: compressor work changes the state of freon, then by again change the state of freon through surface cooler, in these two processes, there is the transfer of heat, thereby realize temperature, regulate object.Utilize this principle, can realize refrigeration and also can realize and heating.Therefore a lot of such air-conditionings all have refrigeration and two kinds of functions of heating present stage.Yet such air-conditioning power consumption is larger, runs counter to, therefore researcher starts to explore and develop to Novel energy-saving air-conditioning with Developing Green.
Common energy-saving type air conditioner is water air-conditioning and ground source heat pump type air-conditioning at present.The former utilizes water under natural environment as cold-producing medium, by processes such as evaporative condensers, reduce room temperature, there is certain refrigeration, under extreme conditions but (as dog days), refrigeration can be had a greatly reduced quality, and it cannot realize heating function himself operation principle of water air-conditioning and structures shape, so the popularization of water air-conditioning has certain technical difficulty.The latter utilizes the geothermal energy resources of underground shallow layer to realize cold and hot conversion, and power consumption reduces greatly and comfort level obviously improves, and once coming out, has just been subject to pursuing of consumer, has market prospects.
Although ground source heat pump type air-conditioning advantage is obvious, meet the requirement of current energy-saving and emission-reduction policy, still there is obvious shortcoming in such air-conditioning.Sum up as follows: although 1. utilize geothermal energy resources realize refrigeration and heat, heat exchange link still relies on freon as cold-producing medium, therefore must need to change its physical state with compressor; Moreover such air-conditioning is integral type structure, all working parts are installed in indoor, so the operating noise of compressor becomes the noise source affecting in people's family life, and after especially going to bed, noise, up to 50 decibels, has a strong impact on sleep quality.2. during compressor operating, himself motor also can generate heat, so this part heat also can scatter through blower fan indoorly, and refrigeration is caused to certain influence, then consumes extra electric energy.3. owing to having adopted water, be that constant source and cold-producing medium carry out heat exchange, so heat exchange unit is twin-tube type structure, in water pipe, overlaps fluorine pipe (fluorine in outer water) and carry out heat exchange with this.This structure has caused heat exchange area less, and heat exchanger effectiveness is low, can not well utilize geothermal energy resources to realize refrigeration or heat-production functions, therefore affects the efficient operation of equipment.Therefore, these defects should be resolved as early as possible.
