Fresh air supplying central air conditioning system utilizing terrestrial heat for radiating cool and heat supply

Abstract

The fresh air supplying central air conditioning system utilizing terrestrial heat for radiating cool and heat supply includes one soil heat exchanging liquid circulation system, two refrigerant circulating systems, one air conditioning water circulating system, one fresh air system and one air exhausting system. In summer, the evaporator and radiating air conditioner absorbs heat from fresh air and the air conditioned area, and the heat is transferred via refrigerant circulating system and dissipated to soil via the soil heat exchanging liquid circulation system. In water, heater is absorbedfrom soil by the soil heat exchanging liquid circulation system, transferred to fresh air and radiating air conditioner via refrigerant circulating system and air conditioning water circulating system.

Description

Technical field: [0001] The invention relates to an air-conditioning system, in particular to a fresh air central air-conditioning system for cooling and heating by geothermal radiation, 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...

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
