Air conditioning system

Abstract

The invention discloses an air conditioning system, which comprises a fresh air machine with a fresh air heat exchanger and a refrigerating main engine and further comprises a circulation machine witha circulating heat exchanger, wherein a refrigerant of the refrigerating main engine sequentially passes through the fresh air heat exchanger and the circulating heat exchanger through a pipeline forcirculation. In the invention, the refrigerating main engine, the fresh air heat exchanger and the circulating heat exchanger are sequentially and circularly communicated through a pipeline, low-temperature chilled water is cooled and dehumidified by the fresh air heat exchanger, and then the circulating return air is cooled through the circulating heat exchanger, so that fresh air pre-cooling capacity heat recovery and the maximum utilization rate of the capacity of a water chilling unit are achieved by sharing one refrigerating unit. Meanwhile, the models of a water pump and a water pipe can be reduced due to the large-temperature-difference small-flow design, the energy consumption of the air conditioning system is reduced, and the initial investment of equipment is reduced.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system. Background technique [0002] In the traditional air-conditioning system with independent temperature and humidity control, the chilled water used by the fresh air unit to treat the fresh air is low-temperature chilled water (water supply: 5-7°C, return water 10-12°C), while the chilled water used by the circulator to treat the return air is medium-temperature chilled water (Water supply: 10-16°C, return water 15-21°C), therefore, it is necessary to set up two working conditions of cold sources separately, so that it is necessary to use multiple refrigeration units to set the working conditions separately, resulting in a large installation space and low utilization efficiency . Contents of the invention [0003] The present invention proposes an air-conditioning system in order to solve the technical problem in the prior art that a plurality of refri...
