Air-conditioning system using earth as heat source

Abstract

The invention discloses an air-conditioning system using the earth as a heat source. According to the air-conditioning system, waste heat discharged by a central air conditioner is collected to be made into steam and to be stored in the earth efficiently, and the steam is taken out of the underground in a heating season. The system adds a waste heat collection system on the basis of a traditionalcentral air conditioner, and the waste heat collection system includes a hot-pressure steam boiler; a traditional cooling tower in a central air-conditioning cooling season is replaced, and cooling water is delivered into the hot-pressure steam boiler to reduce water temperature through evaporation and back to a cooling system. The evaporated water vapor is sent to a hot pressure chamber to be transformed into steam and transported to underground for storage. In winter, the underground hot water is sent back to the hot-pressure steam boiler through a ground source well and returns to the ground source well after being evaporated and cooled, the evaporated water vapor is heated again into high temperature water vapor, and the water in a user circuit is heated by an exchanger.

Description

technical field [0001] The invention relates to an air-conditioning and heating system, in particular to an air-conditioning system that stores waste heat in the air-conditioning cooling season into the ground and takes it out in the air-conditioning heating season. Background technique [0002] Ground source heat pump air conditioning system has been researched and applied in many countries such as Europe and America for decades. In recent years, it has also received extensive attention in China and has been practically applied. The ground source heat pump air conditioning system uses the earth as the cold source (or heat source), uses the intermediate medium (usually water or antifreeze) as the heat carrier, and makes the intermediate medium circulate through the earth in a closed loop (usually composed of plastic pipes) Flow, so as to achieve the purpose of heat exchange with the earth, [0003] Ground source heat pump air conditioning system mainly includes three loops...

Problems solved by technology

In this case, the heat absorption and heat release of the geothermal heat exchanger are unbalanced, and the excess heat (or cold) will accumulate underground, causing the annual average temperature of the underground to change, which in turn affects the output of the geothermal heat exchanger.
