High-temperature refrigeration coupled energy storage cold source air conditioning system with independent control based on temperature and humidity and control method thereof

Abstract

The invention relates to a high-temperature refrigeration coupled energy storage cold source air conditioning system with independent control based on temperature and humidity and a control method thereof. The system comprises a humidity adjusting system and a temperature adjusting system, wherein the humidity adjusting system is used for controlling indoor humidity, the temperature adjusting system is used for controlling indoor temperature, the humidity adjusting system is a fresh air unit with a cold source, and the temperature adjusting system adopts a high-temperature refrigeration coupled energy storage cold source. According to the control method of the system, a cold supply cold water unit, a cold storage cold water unit, an outdoor heat exchange system, a free cold supply heat exchanger, cold storage equipment, an air conditioner cold supply circulating pump and an air conditioner cold storage circulating pump are controlled to start and stop, and different valves are switched to open and close, so that three working conditions of daily cold supply and cold storage, cold supply and cold storage in transition seasons and cold release of an emergency cold source are switched. The system and the control method have the advantages of economy, health, comfort, greenness, environmental friendliness, energy conservation and stability, and the defects of a conventional data room air conditioning cold source system are overcome.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a high temperature refrigeration coupled energy storage cold source air conditioning system based on independent control of temperature and humidity and a control method thereof. Background technique [0002] With the development of my country's economy and society and the increase of population density, the development of the financial industry is expanding rapidly, and the demand for computers is also increasing. Therefore, the application of data computer rooms in society has also received widespread attention. The technical requirements for cooling have increased accordingly. Traditional data center air conditioners use refrigeration and dehumidification + electric heating, and there is a waste of offsetting cold and heat. In order to meet the requirements for dehumidification, lower air-conditioning chilled water temperatures are often used, and the system energy efficiency is lo...

AI Technical Summary

Problems solved by technology

Traditional data room air conditioners use refrigeration dehumidification + electric heating, and there is a waste of cold and heat offsetting. In order to meet the requirements for dehumidification, it is often necessary to use a lower temperature of chilled water in the air conditioner, and the energy efficiency of the system is low.
