Double-cold-source air conditioning system

Abstract

The invention discloses a double-cold-source air conditioning system. The system comprises a water chilling unit and an ice storage unit, wherein the water chilling unit serves as a high-temperature heat source and is used for treating indoor sensible heat loads, and the ice storage unit serves as a low-temperature heat source and is used for treating indoor latent heat loads, and the two units are independently controlled. The ice storage unit comprises a main machine, an ice storage tank, a first heat exchanger and a second heat exchanger, wherein a first branch and a second branch are led out between an outlet of the main machine and an inlet of the ice storage tank in parallel, the other end of the first branch is connected with the first heat exchanger to form an ice storage and coldrelease loop, and the other end of the second branch is connected with the second heat exchanger to form a main machine cold supply loop; and an inlet of the main machine communicates with an outlet of the ice storage tank through a third branch to form an ice storage loop, and opening and closing of each loop are controlled through a control valve. The double-cold-source air conditioning system combines the advantages of high-temperature water and ice storage, and meanwhile the advantages of high energy efficiency and low cost are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system with independent temperature and humidity control using ice storage and high-temperature water as dual cooling sources. Background technique [0002] Conventional air-conditioning systems use a single low-temperature cold source to deal with indoor sensible heat and latent heat loads, resulting in excessive energy consumption, and it is difficult for conventional systems to achieve the dual-parameter control goals of indoor temperature and humidity, which in turn cannot meet the thermal and humid environment requirements of indoor personnel. . Although the conventional dual cold source temperature and humidity independent control system can solve the disadvantages of the conventional air conditioning system, but its own high operating costs exist; and the commonly used air conditioning system that can effectively solve the cost problem is the i...
