A heat exchanger includes a heat exchange tube () and a first water collecting tank (). The first water collecting tank () is provided on the heat exchange tube (), a first water diversion hole () is provided at a bottom portion of the first water collecting tank (), the heat exchange tube () passes through the first water diversion hole (), and the first water diversion hole () has a diameter greater than an outer diameter of the heat exchange tube (). By providing the first water collecting tank (), and making the heat exchange tube () pass through the first water diversion hole () provided on the first water collecting tank (), and leaving a gap between the heat exchange tube () and the first water diversion hole (), the water in the first water collecting tank () evenly flows into the first water diversion hole ().

Heat exchanger, air conditioner, and refrigerating unit

The present application discloses a control method and device of an air conditioning system, for solving the problem of ineffectively controlling the air supply amount of the air conditioning system in the related art. The disclosed control method includes performing at least one of: acquiring a current discharge air temperature of an air conditioning system and a current operating frequency of a fan, and controlling a compressor of the air conditioning system to adjust an operating frequency of the compressor according to the discharge air temperature and the current operating frequency of the fan; or acquiring a current return air temperature of the air conditioning system and a current operating frequency of the compressor, and adjusting an operating frequency of the fan according to the return air temperature and the current operating frequency of the compressor.

Control method and device for air conditioning system and air conditioning system

The present application provides a control method and device for an air conditioning unit, the method including: obtaining a return air temperature, a condensation temperature, an evaporation temperature, compressor parameters, and fan parameters of the air conditioning unit; determining a preset evaporation temperature according to the return air temperature, the condonation temperature, the evaporation temperature, the compressor parameters, the fan parameters, a compressor power curve, and a fan power curve, wherein the sum of a compressor power and a fan power is minimized at the preset evaporation temperature; determining a preset compressor frequency and a preset fan frequency corresponding to the preset evaporation temperature according to the compressor power curve and the fan power curve; controlling a compressor according to the preset compressor frequency; and controlling a fan according to the preset fan frequency.

Control method and device for controlling air conditioning unit, and air conditioning unit

This disclosure provides a control method and control system for two or more air-conditioning water chilling units, and air conditioning system. The control method includes: receiving at least one standby request generated by at least one air-conditioner water chilling unit of the two or more air-conditioning water chilling units based on a standby condition; determining whether or not two or more standby requests are received; generating standby sequence numbers of the air-conditioning water chilling units that send the standby requests according to the standby requests in case where two or more standby requests are received; and closing the air-conditioning water chilling units that send the standby requests according to a preset rule based on the standby sequence numbers.
