Problems solved by technology

In order to avoid condensation on the surface of the heat exchange plate in contact with the indoor air, it is necessary to maintain the surface temperature of the heat exchange plate (about 18-20°C) higher than the dew point temperature of the indoor air (generally 14-17°C), so the refrigerant in the heat exchange plate The temperature (generally 15 ~ 17 ℃) should be significantly higher than the traditional central air-conditioning refrigerant temperature (7 ℃), which leads to a small temperature difference between the heat exchange plate and the indoor air, so that the radiation cooling capacity of the heat exchange plate cannot meet Therefore, when the existing heat exchange plate is used in the air-conditioning and refrigeration system, it needs to be used with additional cooling equipment. However, the structure of the cooling system is complex and the cost is high, which makes the development and application of air-conditioning and refrigeration technology restricted. restricted

Abstract

The invention discloses an evaporator which comprises a heat exchange part and a heat-resistant transmitting plate; one side of the heat-resistant transmitting plate is attached to the surface of theheat exchange part; the heat-resistant transmitting plate is prepared from a material, the heat conductivity coefficient of which is in a range of 0.02-0.2W / mK and the transmittance of which on thermal radiation, the wavelengths of which are 9-11[mu]m is over 50%. The evaporator disclosed by the invention can avoid dew formation of the evaporator, so that the radiating heat exchange efficiency isincreased, and meanwhile, the invention also provides an air conditioning refrigerating system.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an evaporator and an air conditioning refrigeration system. Background technique [0002] In the air-conditioning refrigeration system, the radiative heat exchange plate and the indoor human body are mainly radiative heat exchange, so the thermal comfort is better, and it has gradually attracted attention in recent years. In order to avoid dew condensation on the surface of the heat exchange plate in contact with the indoor air, it is necessary to maintain the surface temperature of the heat exchange plate (about 18-20°C) higher than the dew point temperature of the indoor air (generally 14-17°C), so the refrigerant in the heat exchange plate The temperature (generally 15 ~ 17 ℃) should be significantly higher than the traditional central air-conditioning refrigerant temperature (7 ℃), which leads to a small temperature difference between the heat exchange plate and the indoor air...
