Air conditioning system capable of partial heat recovering and total heat recovering

Abstract

An air conditioning system capable of partial heat recovering and total heat recovering includes a heat recovery heat exchanger, an air conditioning side heat exchanger, a ground source side heat exchanger, a four-way valve, a throttling device and a compressor, wherein the heat recovery heat exchanger is provided with a first water inlet pipe and a first water outlet pipe; the first water inlet pipe is communicated with a water inlet of the heat recovery heat exchanger, the first water outlet pipe is communicated with a water outlet of the heat recovery heat exchanger, and the first water outlet pipe is provided with a hot water pump; the air conditioning side heat exchanger is provided with a second water inlet pipe and a second water outlet pipe; the second water inlet pipe is communicated with a water inlet of the air conditioning side heat exchanger, the second water outlet pipe is communicated with a water outlet of the air conditioning side heat exchanger, and the second water inlet pipe is provided with an air conditioning water pump; the ground source side heat exchanger is provided with a third water inlet pipe and a third water outlet pipe; and the third water inlet pipe is communicated with a water inlet of the ground source side heat exchanger, the third water outlet pipe is communicated with a water outlet of the ground source, and the third water inlet pipe is provided with a ground source water pump. Compared with the prior art, the air conditioning system provided by the invention has the characteristics that fewer system components are used, the cost is low, and the system is simple to control and highly reliable.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system capable of partial heat recovery and full heat recovery. Background technique [0002] With the continuous increase of my country's economic level and the continuous improvement of living standards, people's demand for air conditioners is also constantly improving. Air conditioning has gradually become the basic facility of buildings and a necessity in people's life and work. [0003] The air-conditioning systems in the prior art include two types, the partial heat recovery type and the full heat recovery type. [0004] For example, the Chinese utility model patent with the authorized announcement number CN 201599983U disclosed "an air-cooled heat pump unit capable of full heat recovery" on October 6, 2010. Heater, first four-way valve, gas-liquid separator, throttling mechanism, heat recovery heat exchanger, liquid receiver, air-conditioning...

AI Technical Summary

Problems solved by technology

"The above-mentioned air-cooled chiller with partial heat recovery can ensure the effective recovery and reuse of heat, which not only improves the thermal efficiency, enhances the hot water supply capacity of the air conditioning system, but also protects the environment from heat pollution, environmental protection and energy saving, but It uses two four-way valves and several one-way valves to realize partial heat recovery, the structure is relatively complex, and the cost is also high, and it does not have the function of full heat recovery
