Central air conditioning system at terminal of geothermal heat pump radiation

Abstract

The central air conditioning system at terminal of geothermal heat pump radiation includes soil heat exchange liquid circulation system, refrigerant circulation system, primary and secondary air conditioning water circulation system, and fresh air and air exhausting system. In summer, the terminal obtains heat from the air conditioned area and the heat is transferred via the secondary and the primary air conditioning water system to the refrigerant circulation system and further dissipated to soil via the soil heat exchange liquid circulation system. In winter, heat is obtained from soil and transferred to the air conditioned area. In all seasons, the fresh air and air exhausting system improves the air quality in the air conditioned area. The present invention utilizes the geothermal energy and has high efficiency.

Description

Technical field: [0001] The invention relates to an air-conditioning system, in particular to a geothermal heat pump radiation end central air-conditioning system, which belongs to the technical field of refrigeration and air-conditioning. Background technique: [0002] With the improvement of people's living standards, air conditioners have become a must-have consumer product for comfortable buildings. There are three main configuration methods for air conditioners in existing comfortable buildings: one is to install split units and window units, using freon for direct evaporative refrigeration, the area of ​​the single unit air conditioner is small, the split unit has no fresh air, and the comfort and health of the air conditioning area are poor. The outdoor unit needs to be installed in an outdoor ventilated place, which is difficult to install and maintain, and affects the appearance of the building; the second is to install a household central air-conditioning system, t...

AI Technical Summary

Problems solved by technology

There are three main configuration methods for air conditioners in existing comfortable buildings: one is to install split units and window units, using Freon for direct evaporative refrigeration, the single unit air conditioner has a small area, the split unit has no fresh air, and the comfort and health of the air-conditioned area are poor. The outdoor unit needs to be installed in an outdoor ventilated place, which is difficult to install and maintain and affects the appearance of the building; the second is to install a household central air-conditioning system, that is, an air-cooled hot and cold water unit. The condenser of the main unit is air-cooled, which is bulky and affects the operating efficiency of the main unit. The temperature of the atmospheric environment has a great influence, which occupies valuable building area and consumes a lot of energy; third, the installation of a centralized air-conditioning system requires a centralized computer room, which requires a large one-time investment, high operating costs, waste of energy, and difficult property management

These existing air-conditioning systems generally have two main problems: one is that the air-conditioning system consumes more energy, and the condensation heat of the air-conditioning system is directly discharged into the atmosphere, which brings a series of energy problems and environmental problems, which is not conducive to social development. Sustainable development; Second, people who work and live in an air-conditioned environment for a long time will have adverse effects on their health due to the lack of fresh air and poor indoor air quality
