Abstract

The invention discloses an air conditioner and an air conditioner flow valve control method. The air conditioner comprises at least one indoor unit, an outdoor unit, a water pump and a controller. Theoutdoor unit comprises a compressor, a water refrigerant heat exchanger and a flow valve. The water pump is arranged on a heat source water flow path. The controller is configured to determine the total load of the indoor units according to the current number of the indoor units and the temperature adjusting amount, and the temperature adjusting amount is the difference value between the currenttarget temperatures and the current indoor temperatures of all the indoor units. An opening degree change value of the flow valve is determined according to the total load and the water inlet and outlet temperature difference of the water refrigerant heat exchanger, and the opening degree of the flow valve is controlled based on the opening degree change value to control the water flow, thus the water flow of an air conditioner water source multi-split air conditioning water system is accurately controlled, the unit capacity is ensured, and power waste and water system loss caused by flow increase are avoided while user requirements are met.

Description

technical field [0001] The present application relates to the technical field of air conditioners, and more specifically, to an air conditioner and a method for controlling a flow valve of the air conditioner. Background technique [0002] The variable water flow control system uses the controller embedded in the water-cooled multi-line host to control the opening of the cooling water system valve and the frequency of the water pump, thereby reducing the energy consumption of the cooling water system. The data shows that using the variable water flow control system can save more than 60% of energy consumption at most, and the water source multi-connection with variable flow control is currently being developed. However, problems such as power grid fluctuations, water system scaling, and dirty blockages will cause inaccurate flow. That is, when the flow valve is opened to the same opening degree when it is first installed and after one year of operation, the actual water flow...
