An air conditioning system and its control method

Abstract

The invention discloses an air conditioning system. The air conditioning system comprises an air conditioner cold supply end, a first refrigerating host machine, a second refrigerating host machine, a water storage container and a heat exchanger, wherein the air conditioner cold supply end and the first refrigerating host machine are connected through a first water supply circulating pipeline; the air conditioner cold supply end is provided with a second water supply circulating pipeline; the second refrigerating host machine is connected with the water storage container through a third water supply circulating pipeline; the water storage container is provided with a fourth water supply circulating pipeline; and the heat exchanger is connected between the second water supply circulating pipeline and the fourth water supply circulating pipeline. The invention further discloses a control method of the air conditioning system. The heat exchanger is provided for realizing total isolation of the air conditioner cold supply end from the water storage container to prevent water of the air conditioner cold supply end from leaking into the water storage container, so that the safe and stable operation of the air conditioning system is guaranteed, the refrigerating effect is fully exerted, the refrigerating effect is improved, the operation of the air conditioning system is optimized, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water cold storage air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] With the continuous development of urbanization, more and more large public buildings such as data centers, office buildings, shopping malls, government agencies, entertainment venues, hospitals, hotels, etc. Indispensable important equipment and facilities. The power load of the central air-conditioning system is "heavy during the day and light at night", and it competes with other loads on the power grid to make way for peaks and valleys, which is the main factor causing the peak-valley load difference of the power grid. In order to ensure the safe, reasonable and economical operation of the power grid, encourage users to transfer electricity loads, and realize "shifting peaks and filling valleys", the country implements peak-valley time-of-use electricity prices....

AI Technical Summary

Problems solved by technology

Conventional water storage air conditioning technology, when storing cold, adopts the method of closing the valve to isolate the water at the end of the air conditioner or the cooling end of the air conditioner from the water storage container. If the valve is not closed tightly, the water at the end of the air conditioner will leak into the water storage container , leaked through the water storage container, causing the air-conditioning system to fail to operate normally
