Refrigerating system and control method

Abstract

The invention belongs to the field of air conditioners, and particularly relates to a refrigerating system and a control method. The refrigerating system comprises an outdoor heat exchanger, a compressor, an indoor heat exchanger and a plurality of throttling units; the indoor heat exchanger comprises a plurality of indoor heat exchange parts, the first end of each indoor heat exchange part is connected with the compressor, and the second ends of the indoor heat exchange parts are connected with the throttling units in a one-to-one correspondence mode; and each indoor heat exchange part and the corresponding throttling unit are connected in series to form a plurality of indoor branches which are connected to the air suction end of the compressor and the end, away from the compressor, of the outdoor heat exchanger, and each throttling unit comprises a throttling valve and an electromagnetic valve which are arranged in parallel. According to the refrigerating system and the control method, different air supply modes and dehumidification modes can be selected according to different indoor working conditions, the problems that in the conventional dehumidification process of an air conditioner, the indoor environment temperature is reduced, and comfort is poor are solved, and the problem of simplification of cooling dehumidification modes is solved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a refrigeration system and a control method. Background technique [0002] The dehumidification mode and cooling mode of traditional air conditioners are not much different in essence, such as figure 1 As shown, all are air-conditioning refrigeration processes (1→2), that is, the temperature of the air passing through the air-conditioning evaporator drops, and the water vapor in the air will be liquefied into condensed water and discharged outside, thereby reducing the indoor air humidity. However, this dehumidification mode also reduces the indoor air temperature while reducing the indoor air humidity. Too low air temperature or supply air temperature will easily cause people to feel cold and uncomfortable, and affect the human body's comfort experience of the air conditioner. [0003] In order to achieve dehumidification without cooling down, independent dehumidific...

Problems solved by technology

However, this method only considers raising the air temperature again, and does not consider different indoor heat and humidity load conditions and the air supply mode of the air conditioner, and the implementation method is relatively simple.
