Embodiment Construction

[0018] figure 1 Among them, the low-temperature fluid of the cold source 1 is pressurized by the circulating pump 2, and then enters the fan coil unit 3 with the function of removing condensed water, absorbs the heat passing through the sensible heat of the surface air and the latent heat of water vapor condensation, and enters the radiation heat exchange after heating up The device 4 absorbs the heat radiated from the indoor air to its surface, and flows back to the inlet of the cold source 1 after heating up to complete a cycle. When the temperature entering the radiation heat exchanger is lower than the set value, the water mixing valve 5 is opened , so that the reflux heated fluid is mixed with the cold fluid from the cold source, which increases the temperature of the fluid entering the inlet of the radiation heat exchanger and avoids the problem of condensation on the surface of the radiation heat exchanger.

[0019] The indoor air on the surface of the fan coil unit is ...

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 ...
