Water-cooled air conditioner and its energy-saving control method

Abstract

The invention discloses a water-cooled air conditioner and an energy-saving control method thereof. The water-cooled air conditioner comprises a heat exchange medium circulating loop, a water circulating loop, a water pump frequency conversion module and a controller, the water circulation loop is provided with a water pump and the water side of a water side heat exchanger, the heat exchange medium circulating loop is provided with a compressor and the heat exchange medium side of the water side heat exchanger, a compressor is provided with a sensor, the signal output end of the sensor is connected with the signal input end of the controller, the signal output end of the controller is connected with the signal input end of the water pump frequency conversion module, and the electric output end of the water pump frequency conversion module is connected with the power supply end of the water pump. The water pump and water pump frequency conversion module are arranged in the water-cooled air conditioner to enable the water pump to regulate the water supply amount according to the actual need of the water-cooled air conditioner so as to precisely control the water amount and save energy.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a water-cooled air conditioner and an energy-saving control method thereof. Background technique [0002] At present, air conditioners are widely used in people's daily life, especially central air conditioners. Central air conditioners are often used in large buildings for cooling or heating. Large buildings are generally installed with dozens or hundreds of small water-cooled air conditioners. . At present, there is no water pump in the water-cooled air conditioner, and the public water pump in the water-cooled air-conditioning system of the central air conditioner is used for centralized water supply. However, when one public water pump supplies water to multiple air conditioners, the operation of the compressor in each air conditioner is difficult. It is connected with the public water pump, so the air conditioner often has the problem of unreasonable water supply, ...

Problems solved by technology

At present, there is no water pump in the water-cooled air conditioner, and the public water pump in the water-cooled air-conditioning system of the central air conditioner is used for centralized water supply. However, when one public water pump supplies water to multiple air conditioners, the operation of the compressor in each air conditioner is difficult. It is connected with the public water pump, so the air conditioner often has the problem of unreasonable water supply, and it cannot be accurately controlled according to the cooling and heating load of the room where the air conditioner is located, which increases energy consumption
