Abstract

The invention relates to a floor radiant heating and refrigerating system based on a ground source heat pump, and belongs to the field of heating, ventilation and air conditioning. The system comprises first to fourteenth flow regulating valves, an air volume regulating valve, a first heat exchanger, a second heat exchanger, a water mixing tank, a floor heating pipe, a first buried pipe group, a second buried pipe group and a ground source heat pump unit. The system has the advantages that the outlet water temperature of circulating water of the buried pipe group can be directly used for floor radiation refrigeration, the investment of a radiation refrigeration unit is reduced, only the energy consumption of a water pump is consumed, and the energy consumption of the system is greatly reduced; the heat exchanger is connected in series with the floor heating pipe to ensure that the water inlet temperature of the floor heating pipe is higher than the local dew-point temperature; refrigeration and dehumidification in winter utilize cold energy discharged into ground, so that the energy efficiency of the system is improved; and in the area with the heat load larger than the cold load, the building cold load can be increased by increasing the fresh air volume in summer, then heat stored / released to ground by the ground source heat pump system is balanced, the ground heat accumulation degree is relieved, the investment of auxiliary equipment is reduced, and the indoor air quality is improved.

Description

technical field [0001] The invention belongs to the field of heating, ventilating and air conditioning, and in particular relates to a floor radiation heating and cooling system based on a soil source heat pump. Background technique [0002] Floor radiant heating system has been favored since its inception and has been widely used in northern my country. The floor radiant heating and air-conditioning system uses low-temperature hot water as a medium to heat up the surface of one or more radiant panels in the enclosure structure, and then the radiant panel conducts uniform radiation exchange with other enclosure structures, furniture, heat sources and human bodies in the room. Heat, and finally make the room meet the thermal comfort requirements. Compared with the traditional radiator system, the radiant heating and air-conditioning system has many advantages such as uniform heat flow distribution, high thermal comfort, less building area, hygiene and safety, long service li...
