Heat exchange system based on water source environment-friendly type ground source heat pump

Abstract

The invention discloses a heat exchange system based on a water source environment-friendly type ground source heat pump, and relates to the field of energy conservation and environmental protection.The heat exchange system comprises a terrestrial heat collecting subsystem, a terminal release subsystem, a ground source heat pump unit and a domestic hot water subsystem; the terrestrial heat collecting subsystem comprises a buried pipeline and a ground source side water pump, and the ground source side water pump is arranged on a connecting pipeline between the buried pipeline and the ground source heat pump unit; the terminal release subsystem comprises terminal heat release equipment, terminal refrigeration equipment and an indoor circulating water pump, and the indoor circulating water pump is arranged on a connecting pipeline between the terminal release subsystem and the ground source heat pump unit; and the domestic hot water subsystem comprises a circulating water treatment tank,a water injection pipe, a water utilization pipe and a condensation pipe. According to the heat exchange system, a purification device is installed inside a water storage tank, and the two kinds of terminals in the system are utilized to realize the effect of serving multiple purposes through one machine, so that direct switching between a heat pump heat source and an air conditioner cold sourceis achieved, the ground source heat pump has the advantages of being efficient, energy-saving and small in pollution, and maintenance difficulty and cost are reduced.

Description

Technical field [0001] The invention belongs to the field of energy saving and environmental protection, and particularly relates to a heat exchange system based on a water source environmentally friendly ground source heat pump. Background technique [0002] Environmental pollution and energy crisis have become two major problems in today's society. How to pay the least price while enjoying it has become a consensus of mankind. In this context, green buildings with environmental protection and health as the main characteristics have emerged. Consuming as little energy as possible to create a comfortable environment for buildings has become the development direction of air conditioning. The development and utilization of natural cold / heat energy can bring double benefits of energy saving and environmental protection to air conditioning, so people are paying more and more attention. The underground soil layer is a huge natural heat source with great thermal inertia and little temp...

Problems solved by technology

[0005] The purpose of the present invention is to provide a heat exchange system based on water source environment-friendly ground source heat pump. By installing a purification device inside the water storage tank, two terminals in the system are used to realize one machine with multiple functions, and realize the heat source of the heat pump and the cooling of the air conditioner. The source can be switched directly, which solves the problems of low conversion efficiency, heavy pollution and difficult maintenance of the existing ground source heat pump.
