Modular air conditioning system

Abstract

The invention discloses a modular air conditioning system and an energy regulation control method thereof. The modular air conditioning system comprises one or more air cooling modules, one or more compressors, a water main and a host module, and further comprises a temperature detection unit, wherein each air cooling module is provided with one or more refrigerating systems; each refrigerating system is provided with the one or more compressors; the water main is connected with water pipes of the air cooling modules; the temperature detection unit is used for detecting the water temperature To of the water main; and the host module obtains the current energy demand ratio of the air conditioning system according to the water temperature To of the water main and a set target water temperature Ts, determines the quantity of the compressors needing to operate according to the current energy demand ratio, and performs compressor operating state control accordingly. According to the air conditioning system provided by the invention, energy output is determined according to the current energy demand ratio, results are more accurate, energy output is well matched with the demand, and energy wasting is avoided; and meanwhile, the stable operating condition can be better maintained, and air conditioner comfort degree declining caused by water temperature fluctuations is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a modular combined air conditioning system. Background technique [0002] In the field of central air conditioning, a modular air conditioning system is often used to adjust the air temperature, and the load demand of the air conditioning system is related to the adjustment area. The module combination can be either an air-cooled module combination or a water-cooled module combination. Among them, the air-cooled module uses a heat exchanger to exchange heat between water and refrigerant to produce cold (hot) water. The cold (hot) water is transported to the air-conditioned space through the water circulation system, and then exchanges heat with the air through the indoor heat exchanger. , to achieve room temperature regulation. Due to the limited cooling (heating) load of a single air-cooling module, in practical applications, multiple modules are usually used in combi...
