A combined cooling and heating system

Abstract

The invention relates to a refrigerating and heating combined system. A high temperature cooling water inlet pipe is arranged in the middle of a cold water and hot water diversion tank; the high temperature cooling water inlet pipe extends into a water tank axis; the outlet end of the high temperature cooling water inlet pipe is upward and is connected with a cold water and hot water separation device; a low temperature cooling water outlet pipe which is arranged on the lower portion of the cold water and hot water diversion tank extends into the water tank axis and the inlet end is downward; the middle periphery of the cold water and hot water diversion tank is connected with a high temperature cooling water outlet pipe; the lower portion periphery of the cold water and hot water diversion tank is connected with a low temperature cooling water inlet pipe; the top center of the cold water and hot water diversion tank is connected with a hot water output pipe which is connected with a water inlet pipe of a heating water tank; the high temperature cooling water inlet pipe and the low temperature cooling water outlet pipe are respectively connected with an air conditioning cooling water outlet pipe and an air conditioning cooling water inlet pipe; the high temperature cooling water outlet pipe and the low temperature cooling water inlet pipe are respectively connected with a cooling tower water inlet pipe and a cooling tower water outlet pipe. The refrigerating and heating combined system has the advantages of achieving waste heat utilization of an air conditioning unit, reducing energy consumption of a heating water supplying system and reducing cooling tower loads.

Description

technical field [0001] The invention relates to a water tank for an air-conditioning system, in particular to a cooling and heating combined supply system. Background technique [0002] Large hospitals, hotels, office buildings and other places are equipped with air conditioning systems, which need to be used for cooling in high temperature seasons. The air-conditioning unit is provided with a refrigerant water outlet pipe, a refrigerant water inlet pipe, an air-conditioning cooling water outlet pipe, and an air-conditioning cooling water inlet pipe. The cooling tower is provided with a cooling tower water inlet pipe and a cooling tower outlet pipe. The outlet pipe of the cooling tower is connected with the inlet pipe of the cooling water of the air conditioner. [0003] According to the second law of thermodynamics, heat cannot spontaneously transfer from low-temperature objects to high-temperature objects. To realize this process, the air-conditioning unit must consume a ...

AI Technical Summary

Problems solved by technology

[0004] The existing air-conditioning system and hot water supply system operate independently. On the one hand, the high-temperature cooling water of the air-conditioning system has a large amount of waste heat that needs to be dissipated through the cooling tower. On the other hand, the hot water supply facility needs to consume energy to produce hot water.
