Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model segmentation defrosting air-conditioner.
See accompanying drawing 1, segmentation defrosting air-conditioning system comprises off-premises station and indoor set, off-premises station comprises compressor 1, cross valve 2, outdoor heat exchanger 3, total throttling arrangement 4, first throttle device 5, second throttling arrangement 6 and outdoor fan 9, and indoor set comprises indoor heat exchanger 7 and indoor fan 8.Four ports of cross valve 2 are connected with the other end of indoor heat exchanger 7 with the blast pipe of compressor 1, the air intake duct of compressor 1, the main entrance end of outdoor heat exchanger 3 respectively; Outdoor heat exchanger 3 is divided into two sections, and outdoor heat exchanger 3 upper semisection is connected with one end of first throttle device 5, and outdoor heat exchanger 3 lower semisection is connected with one end of the second throttling arrangement 6; Be connected with one end of total throttling arrangement 4 after the other end of first throttle device 5 gathers with the other end of the second throttling arrangement 6, the other end of total throttling arrangement 4 is connected with one end of indoor heat exchanger 7.
Outdoor heat exchanger 3 is except being divided into two sections to realize and being connected with total throttling arrangement respectively, and also outdoor heat exchanger can be divided into three sections or more sections, every section is connected with total throttling arrangement respectively by a throttling arrangement.
Compressor can be constant speed compressor or frequency-changeable compressor.
Throttling arrangement can be heating power expansion valve or electric expansion valve.
With two-sectional chamber external heat exchanger, operation principle of the present utility model is described below:
See accompanying drawing 1, during refrigeration: cold-producing medium is by the gas of compressor 1 boil down to HTHP, through cross valve 2, deliver to outdoor heat exchanger 3, cool after the two sections of outdoor heat exchanger 3 carry out exchange heat respectively, become gas-liquid mixture or liquid, now first throttle device 5 and the second throttling arrangement 6 standard-sized sheet, then total throttling arrangement 4 is passed through, become the gas-liquid mixture of low-temp low-pressure, then by indoor heat exchanger 7, indoor heat exchanger 7 by exchange heat in room air to cold-producing medium, indoor air temperature reduces, to indoor refrigeration.Cold-producing medium becomes the gas of low-temp low-pressure after indoor heat exchanger heat exchange, by cross valve, then is sucked by compressor, then by turning the gas of HTHP after compressor compresses, completes kind of refrigeration cycle.
When heating: cold-producing medium, by the gas of compressor 1 boil down to HTHP, through cross valve 2, delivers to indoor heat exchanger 7, cools after indoor heat exchanger 7 carries out exchange heat, indoor air is warmed and produces and heat.Cooled cold-producing medium becomes gas-liquid mixture or the liquid of high pressure, deliver to total throttling arrangement 4, become the gas-liquid mixture of low-temp low-pressure, again by outdoor heat exchanger 3, the two sections of outdoor heat exchanger 3 by cold-producing medium exchange heat to outdoor air, now first throttle device 5 and the second throttling arrangement 6 standard-sized sheet.Cold-producing medium becomes the gas of low-temp low-pressure after outdoor heat exchanger heat exchange, then by cross valve, is sucked, then by turning the gas of HTHP after compressor compresses, completing and heating circulation by compressor.
During defrosting: cold-producing medium is by the gas of compressor 1 boil down to HTHP, through cross valve 2, deliver to indoor heat exchanger 7, now indoor fan 8 operates, cool after indoor heat exchanger 7 carries out exchange heat, indoor air is warmed and produces and heat, cooled cold-producing medium becomes the gas-liquid mixture of high pressure, deliver to total throttling arrangement 4, now total throttling arrangement 4 standard-sized sheet, outdoor fan 9 is out of service, cold-producing medium flows into the two sections of outdoor heat exchanger 3 respectively simultaneously, now first throttle device 5 standard-sized sheet, frost layer on outdoor heat exchanger 3 upper semisection outer surface is melted by the cold-producing medium of high temperature, cold-producing medium becomes the gas-liquid mixture of low temperature, in addition, second throttling arrangement 6 throttling, the cold-producing medium flowing into lower semisection becomes the gas-liquid mixture of low-temp low-pressure, then by outdoor heat exchanger 3 lower semisection, the lower semisection of outdoor heat exchanger 3 is by cold-producing medium exchange heat to outdoor air, and cold-producing medium becomes the gas of low-temp low-pressure.Compressor is entered after the gas and vapor permeation of the low temperature gas-liquid two-phase cold-producing medium of outdoor heat exchanger 3 upper semisection and the low-temp low-pressure of lower semisection.After the defrosting of outdoor heat exchanger 3 upper semisection, now the second throttling arrangement 6 standard-sized sheet, the frost layer on outdoor heat exchanger 3 lower semisection outer surface is melted by the cold-producing medium of high temperature, and cold-producing medium becomes the gas-liquid mixture of low temperature; In addition, first throttle device 5 throttling, the cold-producing medium flowing into upper semisection becomes the gas-liquid mixture of low-temp low-pressure, then by outdoor heat exchanger 3 upper semisection, the upper semisection of outdoor heat exchanger 3 is by cold-producing medium exchange heat to outdoor air, and cold-producing medium becomes the gas of low-temp low-pressure.Compressor is entered after the gas and vapor permeation of the low temperature gas-liquid two-phase cold-producing medium of outdoor heat exchanger 3 lower semisection and the low-temp low-pressure of upper semisection.In whole defrost process, cross valve 2 does not commutate, and does segmentation defrosting, can realize continuously heating and defrosting, can also ensure that in defrosting process, room temperature is without obvious reduction outdoor heat exchanger 3.At the end of defrosting, outdoor fan 9 starts, the throttling of total throttling arrangement 4, and first throttle device 5 and the second throttling arrangement 6 standard-sized sheet, recover normal heating operation.
Implementation of the present utility model can have following improvement mode:
Indoor heat exchanger can increase dehumidifying magnetic valve and dehumidifying capillary, realizes the function of constant temperature dehumidification.
Indoor set can increase humidifying component and the new blower fan of the permanent oxygen of configuration, realizes the permanent clean function of the permanent oxygen of constant temperature and humidity.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
