Abstract

The invention belongs to the technical field of heat exchange control and discloses a heat source tower control method. The heat source tower control method comprises the steps of determining the windpressure set value of a heat source tower heat exchange device, or the suction temperature set value of a compressor or the temperature set value of a heat conduction medium flowing into a heat source tower side heat source heat exchange device according to the real-time temperature of the external temperature; and starting the defrosting program when the wind pressure of the heat source tower isless than the wind pressure set value, or the suction temperature of the compressor is less than the suction temperature set value or the temperature of the heat conduction medium flowing into the heat source tower side heat source heat exchange device is less than the temperature set value of the heat conduction medium. Through the heat source tower control method, the parameter set values related to frosting are determined according to the real-time temperature of the external environment; whether the defrosting program is started or not is judged by comparing the relation of the frosting related parameter real-time detection value and the set value, and the frosting degree can be judged accurately. The invention further discloses a heat source tower control device and a heat source tower.

Description

technical field

[0001] The invention relates to the technical field of heat exchange control, in particular to a heat source tower control method, a control device and a heat source tower. Background technique

[0002] In the heat pump heating system, the heat source tower is often used to provide heat for the heat source heat exchanger (such as the evaporator) in the heat pump unit. Such as figure 1 As shown, the conventional heat source tower heat pump heating system includes a condenser 11, and the condenser 11 and the user pipe network 13 form a heat exchange circuit. The high-temperature and high-pressure gaseous refrigerant such as Freon is liquefied in the condenser 11, and the heat released during the liquefaction process heats the return water input into the condenser from the user pipe network 13, and the heated water is output from the condenser 11 to the user pipe network. available to users.

[0003] The output end of the condenser 11 is also connected with a...
