Ground source heat pump air conditioning plant used for supplying warm and cool based on radiation

Abstract

The invention relates to a ground source heat pump air conditioning plant used for supplying warm and cool based on radiation and can realize the refrigeration operation of a ground source heat pump in a high efficiency, ground source water is fully utilized to supply cool indoor at the same time, and meanwhile, the problems of dewing caused by cool supply through radiation, the slow start-up, long preheating time, the complicated control and the like of a floor / a top plate, can be solved. The air conditioning plant comprises a ground source water loop, heat pump sets and a cooling / warming loop; when the air conditioning plant produces chilled water on the heat pump sets and the cooling / warming loop, a small temperature difference heat exchanger (8), a second heat pump set (7) and a firstheat pump set (6) can realize series operation, and the temperature of the chilled water is reduced in a subsection manner; when the air conditioning plant produces heat supplying water, and series operation or parallel operation of the second heat pump set (7) and the first heat pump set (6) are realized.

Description

technical field [0001] The invention relates to a ground-source heat pump air-conditioning system based on a ground-source heat pump, which utilizes floor / roof radiation to supply cooling and heating indoors, and belongs to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] With the continuous acceleration of urbanization and the gradual improvement of people's living standards, building energy consumption has accounted for more than 30% of the total energy consumption of the whole society, and it is growing rapidly. In terms of building energy consumption, the energy consumption of the air conditioning system used to improve the indoor comfort of the building accounts for more than 50% of the total building energy consumption. Therefore, reducing the energy consumption of building air-conditioning systems is of great significance to alleviating energy shortage and realizing energy conservation and emiss...
