Abstract

The invention relates to a refrigerator unit control method and device and refrigeration equipment. The refrigerator unit control method comprises the steps of obtaining the actual liquid level of a water storage tank, comparing the actual liquid level of the water storage tank with a preset control liquid level, and controlling a refrigerator unit to execute a corresponding refrigerator control strategy according to the comparison result. Fine matching control of a water pump, a refrigerator and other equipment can be achieved through the liquid level change of the water storage tank, the stability of the water supply temperature and the water supply pressure is guaranteed, and efficient and stable operation and energy-saving operation of the system are achieved.

Description

technical field [0001] The application belongs to the technical field of chiller unit control, and in particular relates to a chiller unit control method, device and refrigeration equipment. Background technique [0002] Industrial chiller rooms need to ensure the stability of water supply temperature and water supply pressure. However, in actual operation, industrial projects have large water consumption and large load fluctuations. Usually, one chiller unit cannot meet the cooling load demand, and two or more sets are required. The chiller unit design scheme, the traditional chiller unit control adopts manual control mode, according to the experience of the operation and maintenance personnel, manually control the addition and subtraction of the chiller, this method is easy to cause energy waste. In the related technology, the method of the return water temperature of the chiller unit is used to realize the automatic switching of the chiller. When the return water temperat...
