Waterless energy delivery ultra-high-rise building air-conditioning system

Abstract

The invention relates to a waterless heat delivery ultra-high-rise building (such as dozens of storeys and even hundreds of storeys) air-conditioning system and a regulation method thereof. A liquid refrigerant pressurizing delivering device and a C-type gaseous refrigerant pressurizing delivering device are arranged in the air-conditioning system of a building, the liquid refrigerant pressurizing delivering device is started when a refrigerating air conditioner is needed, and the C-type gaseous refrigerant pressurizing delivering device is started when a heating air conditioner is needed, so that the air conditioner in the CN 100473912C patent technology which is favorable for energy saving but has the problem that water scales are easy to form and difficult to clean due to the absence of water is perfected, and a liquid refrigerant or a gaseous refrigerant in an evaporator or a condenser in the system can directly refrigerate or heat air in a room. The implementation cost of the two refrigerant pressurizing delivering devices is basically equivalent to the cost of a facility related to a water medium; meanwhile, a fully sealed structural design concept is provided for key parts related to the two devices; and a pump body is allowed to leak the refrigerant, but the leaked refrigerant is not allowed to enter air space.

Description

technical field [0001] The invention relates to a heating and cooling air-conditioning system for super high-rise buildings (for example, tens of floors or even hundreds of floors) without using water medium as an auxiliary transmission of cold or heat. 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 conditioning through the winding pipeline. . Therefore, it...

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"
