Air circulation type ground-source air-conditioning system

Abstract

The invention provides an air circulation type ground-source air-conditioning system comprising an indoor air outlet, a ground air discharging pipeline, a circulating fan, a ground heat exchanger, a ground air intake pipeline, an indoor air inlet and an air supply fan. The indoor air outlet, the ground air discharging pipeline, the circulating fan, the ground heat exchanger, the ground air intake pipeline and the indoor air inlet are sequentially connected to form an air circulating loop, and the air supply fan is connected with the ground air intake pipeline. By utilizing the characteristic of constant temperature of a ground shallow surface, the air circulation type ground-source air-conditioning system disclosed by the invention can achieve the aims of refrigerating (supplying cold air) in summer and heating (supplying hot air) in winter, and is a novel highly-efficient, energy-saving and pollution-free air-conditioning system capable of supplying hot air and refrigerating (supplying cold air) by utilizing renewable energy resources. The air circulation type ground-source air-conditioning system saves 70-80% of energy compared with a common air-conditioning system and more than 40% of energy compared with a ground-source heat pump air-conditioning system, and has lower initial investment compared with the ground-source heat pump air-conditioning system. Therefore, the air circulation type ground-source air-conditioning system can be widely applied to buildings, such as commercial buildings, public buildings, houses, apartments, schools, hospitals and the like.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to an air circulation ground source air conditioning system. Background technique [0002] With the development of the economy and the improvement of people's living standards, the heating and cooling of public buildings and residential buildings has become a common demand. Traditional air-conditioning systems usually need to set cold sources (refrigerators) and heat sources (boilers) separately to meet the cooling and heating needs, which not only consumes a lot of energy, but also produces carbon dioxide or freon that pollutes the environment, causing harm to the living environment of human beings. destroy. [0003] Geothermal is a green renewable energy similar to solar energy. The temperature of the underground surface layer is maintained at around 20°C all year round. The existing ground source heat pump air conditioning system uses soil as the heat source, water as the heat excha...

AI Technical Summary

Problems solved by technology

This kind of ground source heat pump air conditioning system is energy-saving and environmentally friendly, and is being used more and more, but because it still uses water as the medium for indirect heat exchange, the heat exchange effect is limited

In addition, heat exchangers need to be installed indoors, which takes up space and requires a large investment.
