Radiation air conditioning system based on combination of evaporative cooling and mechanical refrigeration

Abstract

The invention discloses a radiation air conditioning system based on combination of evaporative cooling and mechanical refrigeration, comprising a cold / hot water unit A combining evaporative cooling and mechanical refrigeration, an evaporative cooling fresh air handling unit B, capillary terminals C arranged on the roof and walls inside the room at the radiation terminal and PERT cold / hot coils D laid on the floor inside the room at the radiation terminal, wherein a replacement ventilator is arranged at the air inlet inside the room at the radiation terminal; the above components are connected by pipelines to form a circuit; and the cold / hot water unit A comprises an evaporative cold water unit E and an air-cooled heat pump type cold / hot water unit F. The radiation air conditioning system combines evaporative cooling and mechanical refrigeration, expands the application range of the evaporative cooling technology and is not only suitable for the northwestern dry areas but also widely applied to the medium-humidity and high-humidity areas. In addition, the radiation air conditioning system can supply cold to the radiation terminal in summer and supply heat in winter, realize dual purposes and reduce initial investment.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an air-conditioning system integrated with a hot water unit based on evaporative cooling and mechanical refrigeration, an evaporative cooling fresh air unit, a radiation terminal and a displacement ventilator. Background technique [0002] In recent years, radiant air conditioners have become more and more popular due to their comfort. However, at present, radiant air-conditioning systems mostly use the method of mixing traditional mechanical refrigeration and cold water at room temperature to produce high-temperature cold water, which not only consumes a lot of energy and pollutes the environment, but also causes waste of energy due to the mixing of cold and hot water. [0003] Although evaporative cooling technology can be used to produce high-temperature cold water in dry areas, it is not suitable for medium-humidity areas and high-humidity areas...

Problems solved by technology

However, the current radiant air-conditioning system mostly adopts the method of mixing traditional mechanical refrigeration and cold water at room temperature to produce high-temperature cold water, which not only consumes a lot of energy and pollutes the environment, but also causes waste of energy due to the mixing of cold and hot water.

[0003] Although evaporative cooling technology can be used to produce high-temperature cold water in dry areas, it is not suitable for medium-humidity areas and high-humidity areas due to the limitation of meteorological conditions.
