Geothermal heat pump air conditioning system for file storeroom based on radiating terminal

Abstract

The invention relates to a ground source heat pump air-conditioning system for a file room which is based on a radiation tail end; the ground source heat pump air-conditioning system comprises an underground heat exchanger system, a heat pump unit system, the radiation tail end and a fresh air handling unit system; wherein, the underground heat exchanger system is connected with the heat pump unit system, the heat pump unit system is connected with the radiation tail end and the fresh air handling unit system; an air-conditioning water collector and a water distributor of the heat pump unit are connected with the radiation tail end and the fresh air handling unit system, thereby providing cold water with higher temperature for the radiation tail end and the fresh air handling unit system; the cold water flows into a capillary coil of the radiation tail end for carrying out the indoor cooling, the cold water flows into a small refrigerating machine for carrying out further cooling and temperature decrease, the low temperature cold water after the temperature thereof is decreased flows into a cooling coil of the fresh air handing unit for carrying out the cooling and the dehumidification to fresh air, and the fresh air after cooled and dehumidified is sent to the indoor space for providing the fresh air for the indoor space via an air supply section. As the heat pump unit system only needs to produce the cold water with the higher temperature, the work burden of the heat pump unit is reduced, and the working efficiency of the heat pump unit is improved.

Description

technical field [0001] The invention relates to a heat pump air-conditioning system in the technical field of refrigeration, in particular to a ground-source heat pump air-conditioning system for archival warehouses based on radiation terminals. Background technique [0002] The energy issue is a major issue facing human development, and the coordinated development of energy and the environment has become a trend. Ground source heat pump is an effective form of energy utilization. It uses the soil as a heat and cold source. Through the heat exchange medium, it dissipates heat to the soil in summer, absorbs heat from the soil in winter, and then supplies cooling and heating to the building through the heat pump unit. The soil source belongs to renewable energy, and the use of renewable energy as a cold and heat source for building cooling and heating is energy-saving and environmentally friendly. At the same time, due to the particularity of the archives warehouse, the wareh...
