Embodiment Construction

[0026] Specific embodiments of the present invention are described in detail below.

[0027] see figure 1 As shown, this embodiment proposes a constant temperature dehumidification air conditioner, and the air conditioner includes a control unit, a refrigerant circuit, a temperature detection unit and a timing unit.

[0028] Wherein, the control unit is used to receive the indoor temperature RT detected by the temperature detection unit and the set temperature ST set by the remote controller, calculate the temperature difference E=RT-ST, and control the compressor 101, the four-way valve 105 and the throttle according to the temperature difference E The state of the flow device a104 and the throttling device b106 makes the air conditioner work in the cooling and dehumidification mode, the reheating and dehumidification mode or the heating and dehumidification mode. In addition, the control unit receives timing from the timing unit, and when the air conditioner switches from o...

Abstract

The invention relates to a constant-temperature dehumidifying air conditioner and a dehumidifying method. The air conditioner comprises a compressor, a cross valve, an outdoor heat exchanger, throttling devices a and b, and an indoor heat exchanger which are connected through a refrigerating pipeline, wherein the indoor heat exchanger comprises a first heat exchanger and a second heat exchanger which are connected through the throttling device b, and the air conditioner is controlled to switch among a refrigerating dehumidifying mode, a reheating dehumidifying mode or a heating dehumidifying mode through changing the states of the compressor, the cross valve and the throttling devices a and b according to the difference between the indoor temperature and the set temperature. The air conditioner has the advantages that while the air conditioner dehumidifies, the indoor temperature is maintained near the set temperature value, and the comfortable indoor environment is realized; meanwhile, the adverse effect on the air conditioner by the frequent switching of the running modes is avoided, so the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner capable of realizing constant temperature dehumidification and a constant temperature dehumidification method for the air conditioner. Background technique [0002] Existing air conditioners all have a dehumidification function, and in the dehumidification operation mode and the cooling operation mode of the air conditioner, the flow direction of the refrigerant in the refrigeration pipeline is the same. Therefore, the existing air conditioners have no essential difference between the dehumidification and cooling operation modes. The difference is only that the indoor fan is controlled at a slightly lower wind speed in the dehumidification operation mode than in the cooling operation mode or by intermittent operation. In the dehumidification operation mode, the temperature of the room cannot be controlled, and low-temperature air supply...
