Aqueous-medium-energy-transmission-free refrigerating-heating air-conditioning system for super-high-rise building and conditioning method thereof

Abstract

The invention relates to an aqueous-medium-energy-transmission-free refrigerating-heating air-conditioning system for a super-high-rise building (such as dozens of floors or even hundreds of floors) and a conditioning method thereof. According to the aqueous-medium-energy-transmission-free refrigerating-heating air-conditioning system, a liquid refrigerant pressurized dispensing device and a class-D gas refrigerant pressurized dispensing device are additionally arranged in a building refrigerating-heating air-conditioning system, the liquid refrigerant pressurized dispensing device is started up when the refrigerating air-conditioning is required, and the class-D gas refrigerant pressurized dispensing device is started up when the heating air-conditioning is required, so that the energy conservation is favored, and the troubles that the scaling is easy and the scale is difficult to remove due to no water in the patent CN 100473912C are solved; and a liquid refrigerant or gas refrigerant in an evaporator or condenser in the system can directly carry out refrigerating / heating air-conditioning on air in rooms. The implementation cost of the two refrigerant pressurized dispensing devices is basically equivalent to the cost of facilities involved in omitted aqueous media; and meanwhile, a fully-sealed type structural design concept, i.e., a pump body is allowed to leak the refrigerants, however, the leaked refrigerants are not allowed to enter the airspace, is provided for key components involved in the two devices.

Description

technical field [0001] The invention relates to a heating and cooling air-conditioning system for super high-rise buildings (for example, dozens of floors or even hundreds of floors) without using water medium as an auxiliary transmission of cold or heat and a cooling and heating control operation method thereof. Background technique: [0002] In current high-rise building projects, especially in the design of heating and cooling air-conditioning systems in super high-rise building projects, it is a common technical means to use water as the cooling medium to transfer cold and heat to terminal equipment (such as: fan coil units and water-cooled heaters, etc.) . This is because: [0003] It is difficult to directly drive the rated flow of liquid refrigerant by relying only on the force of the high and low pressure difference caused by the compressor in the air conditioning system, and enter the super high-rise building tens of meters, or even hundreds of meters, for room air...

AI Technical Summary

Problems solved by technology

Its shortcoming is that it has high requirements on water quality, usually in order to slow down the scale formation (affecting heat conduction) in the pipe network that distributes cooling or heat, especially the terminal equipment, it is necessary to use chemicals every one or two years Unclog a huge heat exchange system made up of a network of water pipes

——If only relying on the above-mentioned condensing pressure to promote the gaseous refrigerant to meet the heating demand of not too high buildings, the problem is not very big. However, in super high-rise buildings, it is likely that the gaseous refrigerant directly implements heating and air conditioning to the air. Appears to be "overwhelmed"
