Ground source heat pump type air conditioner group public water supply system

Abstract

The invention provides a ground source heat pump type air conditioner group public water supply system, wherein a large deep well or an underground water storage pool with a certain depth is used as a water source, and the public underground circulating water supply system is built so as to support heat exchange between a ground source heat pump type air conditioner group and the ground. According to the technical scheme, a central pump station is built and communicated with each ground source heat pump type air conditioner through double pipes which are a water supply pipe and a water return pipe, the system is totally closed relatively, the siphon principle is adopted once normal operation of water supply is conducted, and water supply can be conducted with low energy consumption. Multiple levels of water pumps are connected in series, and each level of water pumps is provided with a bypass provided with a one-way valve. After the system operates normally, only the water pumps with high flow and low lift need to work, and other water pumps are automatically switched off.

Description

technical field

[0001] The invention relates to the use of public water supply system, so many ground source heat pump air conditioners can effectively exchange heat with the ground in many cases. Background technique

[0002] Using the heat exchange with the earth, the energy efficiency ratio of the air conditioner can be doubled. By pumping and filling two small deep wells, the heat exchange between this type of air conditioner and the earth can be easily realized by using circulating groundwater. But in some so-called dry water areas, high-rise residential areas in many places today, this type of air conditioner is just useless. Contents of the invention

[0003] The present invention provides circulating groundwater for air conditioners in many single rooms by establishing public groundwater sources and a central pumping station, so that the air conditioners can exchange heat with the ground through the groundwater. The water supply system is relatively fully enclose...
