Problems solved by technology

Obviously, the comfort and dehumidification effect are very poor. There are also some air conditioners that use a part of electric heating to balance the cooling capacity, but the electric heating efficiency is low (the calorific value does not exceed the input power). Generally, the cool

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1 ~ Figure 3 As shown, the air conditioner of the present invention includes a circulation loop formed by sequentially connecting a compressor, an electromagnetic four-way valve, an evaporator, a throttling device and a condenser, and the compressor, an electromagnetic four-way valve, an evaporator, and a throttling The device and the condenser are respectively provided with at least two to form at least two independent circulation loops. The duration of the defrosting process of the air conditioner depends on the energy of the defrosting, and the total defrosting energy of the air conditioner = the output power of the compressor + the heat of the compressor body + the heat absorbed in the room + the heat of the refrigerant body in the room. To increase the total energy of defrosting, only the indoor heat absorption can be increa...

Abstract

The present invention discloses an air-conditioner which can be used for continuous heating and constant temperature dehumidification and has features of improving the indoor amenity in the defrost dehumidification process. The air-conditioner includes compressors, electromagnetic four-way valves, evaporators, throttling devices and condensers connected in sequence to form recycle loops, at least two compressors, electromagnetic four-way valves, evaporators, throttling devices and condensers are respectively provided to form at least two independent recycle loops. By setting at least two independent recycle loops, part of recycle loop adopts heat-production operation in the defrost and dehumidification process, while part of recycle loop adopts refrigeration operation so that it can continuously provide heat in the defrost and dehumidification process, to satisfy the amenity requirement of defrost and dehumidification, and can effectively prevent greater fluctuation of the indoor temperature, especially suitable for promoting in the use of heat pump air conditioning system.

Description

technical field [0001] The invention relates to a heat pump air conditioner, in particular to an air conditioner which can be used for continuous heating and constant temperature dehumidification. Background technique [0002] At present, the existing heat pump air-conditioning system generally consists of a compressor, a four-way valve, a condenser, a throttling device, and an evaporator connected in sequence. The air conditioner completes the cooling and heating functions of the air conditioner by switching the four-way valve. [0003] When the air conditioner heat pump is working, it is generally believed that when the outdoor temperature is lower than 5.5°C, the outdoor condenser will frost. When the frost layer reaches a certain thickness, the heating effect will be seriously affected. At this time, the outdoor heat exchanger needs to be defrosted. Now The defrosting method of conventional air conditioner heating is generally as follows: when the defrosting conditions a...
