Multi-functional efficient air conditioning system

Abstract

The invention discloses a multi-functional efficient air conditioning system. A source-end refrigerant circulating system is simple, reliable and low in production cost. A middle buffer energy-storagesystem comprises a buffer energy storage-transduction tank, a high-temperature heat storage-exchange tank and counter-flow circulating reversing pump valves. By using a natural gravity circulation technology, complementation of high-temperature heat recycling and storage and efficient energy storage of an air conditioner is achieved without power, and the aims of multi-functional application of efficient hot water production while heating or defrosting, free hot water recycling while reliable heat supply or comfortable refrigeration, and total-power efficient hot water production in a transition season are achieved. The system has the advantages of having fewer pump valves and many functioning patterns, and being low in operation energy consumption and stable and easy to control.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a multifunctional high-efficiency air-conditioning system. Background technique [0002] In the existing technology of hot water, refrigeration, heating and triple air-conditioning system, because there is no scientifically designed intermediate energy storage subsystem or only a simple heat storage tank, in order to achieve efficient and stable operation, more and more complex methods are used to realize it. For example: add more four-way reversing valves, one-way valves, and stop valves to switch between hot water and air conditioning functions, add more and larger water-to-water heat exchangers to obtain full power for hot water production, and use Expensive intelligent control devices are used to obtain unsatisfactory defrosting and heating functions, and more complex production methods and control technologies are used to achieve fast, energy-s...
