Water storage central air conditioning system and optimal control method

Abstract

The invention discloses a water storage central air conditioning system and an optimal control method. The water storage central air conditioning system comprises a refrigeration host, a chilled water pump, a water storage tank, a V1 valve, a V2 valve, a V3 valve, a V4 valve, a V5 valve and a V6 valve. The V1 valve, the V3 valve, the refrigeration hos, the chilled water pump and the V2 valve are connected through a pipeline to form a passage. The V1 valve, the V4 valve, the water storage tank, the V6 valve and the V2 valve are connected through a pipeline to form a passage. The input end of the V3 valve is arranged on the pipeline between the V1 valve and the V4 valve. The V5 valve is connected to the pipeline between the refrigeration host and the chilled water pump and the pipeline between the water storage tank and the V6 valve. The chilled water pump is arranged on the pipeline between the V2 valve and the V6 valve. According to the water storage central air conditioning system and the optimal control method, the refrigeration host, the chilled water pump and the water storage tank are arranged, so that the cooling capacity is stored at night for cooling during the day, the electric energy is saved, and the economy is high; and the V1 valve, the V2 valve, the V3 valve, the V4 valve, the V5 valve and the V6 valve can adopt multiple operation ways to be controlled.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning energy-saving equipment, in particular to a water-cooled storage central air-conditioning system and an optimal control method. Background technique [0002] Air conditioners have become an inseparable part of daily life, creating a comfortable indoor environment for people and improving people's lives. However, the power of air conditioners is too large and the loss of electric energy is large. The air conditioner is used all the time, and the air conditioner is cooled by the refrigerator for the air conditioning system. It consumes a lot of electric energy for long-term use. During the peak period of electricity consumption during the day, the electricity price is relatively high at night. The economy of traditional air conditioners is poor. The service life of the freezer, so it is urgent to introduce an air conditioner, which uses the special electricity price policy of the go...
