Problems solved by technology

The defect of the traditional technology is: the indoor air has a certain humidity, the general humidity is about 75%, and the moisture in the air is easy to be liquefied when it contacts the surface of the lower temperature board, thus condensing to form water droplets
[0004] In this case, it seriously affects the comfort of indoor cooling
Even if the initial indoor temperature is high and needs to be cooled quickly, the cooling of the cold radiant ceiling still needs to wait for the regulation of the indoor air humidity, resulting in a lag in cooling
At the same time, in the process of waiting for the indoor air humidity to be adjusted, the cooling of the cold radiant ceiling cannot directly use the 7°C low-temperature cooling water prepared by the compressor. cooling loss

Embodiment 1

[0033] see Figure 1 to Figure 3 , the embodiment of the present invention provides an anti-condensation cold radiation system with a dehumidification system, including a dehumidification system, an air outlet 1 connected to the dehumidification system, and a cold radiation plate 2; wherein, the dehumidification system includes an air intake fan and a ventilation duct 3 1. Dehumidifier; a plurality of ventilation ducts 3 are arranged in parallel; the intake fan and the dehumidifier are respectively arranged at the intake end of the ventilation duct 3; a plurality of air outlets 1 are arranged on both sides along the direction in which the ventilation duct 3 extends; The cold radiant panel 2 is installed on the side of the ventilation duct 3, and its installation orientation is directly opposite to the air outlet 1, and the air outlet direction of the air outlet 1 is parallel to the surface of the cold radiant panel 2, so that the dry fresh air flows on the cold radiant panel 2....

Embodiment 2

[0043] The difference between this embodiment and the first embodiment lies in the arrangement of the air outlets 1, and according to the principle of fluid mechanics, the flow of dry air produces different effects.

[0044] see Figure 5 , specifically, the air outlets 1 on the opposite sides of the two adjacent air exchange ducts 3 are arranged in a staggered position. At this time, there is no other air outlet 1 opposite to each air outlet 1 , and the sprayed dry air will not be affected by the dry air coming in the opposite direction. Simply, the dry air ejected from each air outlet 1 will form an air duct, and the flow directions of adjacent air ducts are opposite. Then, at the adjacent boundary of adjacent air ducts, the dry air flowing in opposite directions will slow down the flow velocity and form swirling turbulent flow. The swirling turbulence will stay longer in the middle of the cold radiation plate 2 and become a part of the air curtain. Until the kinetic ener...

Embodiment 3

[0049] This embodiment provides an anti-condensation method for an anti-condensation cold radiation system with a dehumidification system, which is characterized in that dry air is prepared by the dehumidification system, and the dry air is blown out along the surface of the cold radiation plate 2 on the side of the cold radiation plate 2. Air, make the dry air form an air curtain on the surface of the cold radiant panel 2, and isolate the surface of the cold radiant panel 2 from the indoor air.

[0050] Due to the low relative humidity of the dry air, the local dew point temperature on the surface of the cold radiation plate 2 decreases accordingly, and it is not easy to condense and dew, so as to achieve the purpose of anti-condensation. Furthermore, the cold radiant panel 2 can provide cooling with high cooling power in a short time without waiting for the air humidity in the whole room to drop to the set value before gradually increasing the cooling power, and the initial r...

Abstract

The invention provides an anti-condensation cold radiation system with a dehumidification system. The system comprises the dehumidification system, air outlets connected with the dehumidification system and cold radiation plates, wherein the dehumidification system comprises an air inlet fan, ventilation pipelines and a dehumidifier, the plurality of ventilation pipelines extend horizontally and are arranged in parallel, the air inlet fan and the dehumidifier are arranged at the air inlet ends of the ventilation pipelines, the plurality of air outlets are arranged on the two sides of the ventilation pipelines in the extending direction of the ventilation pipelines, the cold radiation plates are installed on the two sides of the ventilation pipelines, the installation heights of the cold radiation plates are flush with the upper edges of the air outlets, and the air outlet directions of the air outlets are parallel to the boards of the cold radiation plates. According to the cold radiation system, air curtains are formed on the surfaces of the cold radiation plates through the dehumidification system, condensation is prevented, and the cooling efficiency is improved at an initial starting stage of the cold radiation system.

Description

technical field [0001] The invention relates to the technical field of building materials and indoor cooling, in particular to an anti-condensation cold radiation system with a dehumidification system and an anti-condensation method. Background technique [0002] The cold radiation technology was proposed by foreign countries and introduced into China many years ago, using the heat transfer method of infrared radiation to cool the room. The disadvantage of the traditional technology is that the indoor air has a certain humidity, the general humidity is about 75%, and the moisture in the air is easy to be liquefied when it contacts the surface of the lower temperature board, thereby condensing to form water droplets. The current method to overcome this technical defect is: through the control of the fresh air system, monitor and regulate the humidity of the indoor air, and at the same time control the temperature of the refrigeration, so that the temperature of the surface of...
