Cold supply, dehumidification and temperature adjustment component of radiation heat exchanger

Abstract

The invention discloses a cold supply, dehumidification and temperature adjustment component of a radiation heat exchanger. The component comprises a cold source, a circulating pump, a fan pipe coil with function of removing condensed water, the radiation heat exchanger, a connecting pipeline and a working substance. The component is characterized in that the fan pipe coil with the function of removing the condensed water and the radiation heat exchanger are arranged in the same ventilated room. In cold supply, low-temperature fluid passes through the fan pipe coil with the function of removing the condensed water and carries out treatments of cooling, dehumidification and dew point depression on air circulating on the surface of an outer wing of the fan pipe coil. On the premise of ensuring no risk of condensed dew on the surface of the radiation heat exchanger, the component effectively reduces the temperature of the low-temperature fluid entering the radiation heat exchanger, increases the cold supply quantity of the radiation heat exchanger and improves the comfort of cold supply.

Description

technical field [0001] The invention belongs to the technical field of terminal heat exchangers for cooling and heating of buildings. In particular, it is an end heat exchanger component that uses heat radiation to provide cooling, dehumidification and temperature adjustment for buildings with high efficiency and low noise. Background technique [0002] At present, radiation heat exchangers have the advantages of no noise and no blowing sensation when cooling and heating buildings. The temperature of the input cold fluid can be higher, which improves the efficiency of cold source equipment. However, there are some problems in cooling: [0003] ① It can only remove the sensible heat in the air, which increases the relative humidity of the air and makes the comfort of the air conditioner worse. [0004] ②The temperature of the cold fluid entering the radiation heat exchanger should not be too low, otherwise it will cause condensation on the surface of the heat exchanger. To ...

AI Technical Summary

Problems solved by technology

[0003] ①It can only remove the sensible heat in the air, which increases the relative humidity of the air and makes the comfort of the air conditioner worse

To make the heat transfer per unit area too small, which affects the indoor cooling effect

[0005] ③The equipment for controlling condensation and adjusting the temperature of the fluid entering the radiation heat exchanger is complicated, has low reliability, and requires a large initial investment
