Problems solved by technology
[0002] For the air conditioning system with capillary throttling, under the operating condition of low evaporation temperature, the refrigerant liquid pressure and temperature in the gas-liquid separator are very low, the suction specific volume increases, and the system cycle efficiency decreases
In the air-conditioning system using a water-cooled condenser, the temperature of the cooling water is usually high, resulting in a low cooling cycle efficiency. Therefore, how to effectively use the temperature of the cooling water to solve the problems existing in the gas-liquid separator and improve the system cycle efficiency, then It is the subject that the present invention faces

The invention provides an air-conditioning system with water circulation, including a refrigeration circulation system, a cooling water circulation system and a controller. . A gas-liquid separator, the cooling water circulation system includes a water tank, a cooling water circulation pipeline, a heat dissipation coil is arranged in the gas-liquid separator, and the cooling water of the water-cooled condenser flows through the heat dissipation coil, and The refrigerant liquid performs heat exchange. A method of controlling the water cycle is also provided. The invention utilizes the cooling water with higher temperature to exchange heat with the refrigerant liquid with lower temperature in the gas-liquid separator, which improves the pressure and temperature of the refrigerant and solves the low-pressure backlash in the air-conditioning system when operating at a low evaporation temperature. At the same time, the temperature of the cooling water is reduced, the power consumption of the cooling water is shared, and the efficiency of the cooling water cycle is improved.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and in particular relates to an air-conditioning system with water circulation and a control method for the water circulation. Background technique [0002] For the air-conditioning system with capillary throttling, under the operating condition of low evaporation temperature, the pressure and temperature of the refrigerant liquid in the gas-liquid separator are very low, the suction specific volume increases, and the cycle efficiency of the system decreases. In the air-conditioning system using a water-cooled condenser, the temperature of the cooling water is usually high, resulting in a low cooling cycle efficiency. Therefore, how to effectively use the temperature of the cooling water to solve the problems existing in the gas-liquid separator and improve the system cycle efficiency, then It is the problem faced by the present invention.
