Abstract

The invention discloses an air conditioner and an AHU unit temperature control method. The air conditioner comprises a compressor, a three-pipe heat recovery external unit and an AHU unit, and the AHU unit comprises a plurality of sets of refrigerating coils connected in parallel and a plurality of sets of heating coils connected in parallel, and a liquid pipe of each refrigerating coil is provided with a refrigerating electronic expansion valve; gas pipes of the refrigerating coils are connected with a low-temperature and low-pressure gas pipeline, a liquid pipe of each heating coil is provided with a heating electronic expansion valve, and gas pipes of the heating coils are connected with a high-temperature and high-pressure gas pipeline through a first electromagnetic valve; the gas pipes of the heating coils are connected with the low-temperature and low-pressure gas pipeline through a second electromagnetic valve; a controller is configured to obtain indoor environment information and user setting information; and the refrigerating electronic expansion valves and the heating electronic expansion valves are controlled based on the indoor environment information and the user setting information, so that the energy consumption of the AHU unit is reduced while the dehumidification, refrigeration and heating effects are ensured.

Description

technical field [0001] The present application relates to the field of air conditioning control, and more specifically, to a method for controlling the temperature of an air conditioner and an AHU unit. Background technique [0002] The AHU unit of the air conditioner is a centralized air treatment system, which can dehumidify, cool and heat the air. Compared with the fan coil plus fresh air system and unitary air conditioner, the AHU unit has a large air volume and high air quality. High, energy saving and other advantages. [0003] In the prior art, the refrigeration coil of the AHU unit generally uses a single large heat exchanger. When the outdoor unit outputs a low load capacity, its evaporation temperature is high, which is not conducive to dehumidification. At the same time, in order to meet the dehumidification needs to maintain a low evaporation temperature, The outdoor unit needs to output an overloaded load capacity. At this time, the cooling capacity may be exce...
