Cooling and heating air-conditioning system for super high-rise buildings with energy transmission without water medium and its control method

Abstract

The invention provides a low-efficiency circulating energy transmission super high-rise building (for example, dozens of storeys and even hundreds of storeys) air conditioner system free of fluid molecule leakage and replacing a large-power water pump with a small-power refrigerating agent pump. By adding liquid state and gas state refrigerating agent pressurizing distribution devices in the air conditioner system of a building, when refrigerating of an air conditioner is needed, the liquid state refrigerating agent pressurizing distribution device is started; when heating of the air conditioner is needed, the gas state refrigerating agent pressurizing distribution device is started; the purpose is to make the CN 100473912C patent technology facilitating energy conservation and having the troublesome that limescale forming is easily caused by water and limescale is difficult to remove perfect, and refrigerating or heating of the air conditioner is implemented in the manner that a liquid state refrigerating agent or a gas state refrigerating agent in an evaporator or a condenser in a system can directly act on air in a room. The implementation cost of the above two refrigerating agent pressurizing distribution devices is basically equivalent to the cost of omitted facilities related to aqueous media; and meanwhile, the full-seal type structural design concept is put forward for parts related to the two devices, and that is to say, a pump body is allowed to leak a refrigerating agent, but the leaked refrigerating agent is definitely not allowed to enter the atmospheric 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. ——Obviously: the present invention has utilized the thermal engineering principle that " latent heat " exchange amount is far greater than " sensible heat " exchange amount. [0002] Background technique: [0003] 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: [0004] 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 th...

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"
