Abstract: A radiation heat exchanging air conditioning system and a radiation heat exchanging ceiling thereof are disclosed. The air conditioning system includes a heat pump system (7) and a water circulation system (8), and water circulation system (8) includes a heat exchanging device (11) for water, a pump (9), a heat exchanging device (10) for air, a radiation heat exchanging ceiling (20) and air outlets (15). The heat is exchanged between the heat exchanging device (11) for water and the heat pump system (7). The radiation heat exchanging ceiling (20) includes a metal ceiling panel (1) and a heat exchanging coil (2), said heat exchanging coil (2) is installed on the poor thermal-conductivity coil brackets (4) mounted on the upper surface of the metal ceiling panel (1), thus leading to the short distance and no direct contact between the heat exchanging coil (2) and the metal ceiling panel (1).

Abstract: An evaporator base pan assembly of an air-cooled display cabinet is provided. The evaporator base pan assembly includes an enclosure, an evaporator base pan, and a ventilation panel that are arranged sequentially from bottom to top, where an outer side of the evaporator base pan extends outward and bends downward to form a hook portion; the evaporator base pan is hooked to an upper end of the enclosure through the hook portion; a bottom portion of the ventilation panel abuts on an upper edge of the evaporator base pan; the bottom portion of the ventilation panel extends downward to form a limiting portion; and the limiting portion is located on an outer side of the hook portion.

Abstract: Disclosed area reinforcing thermal radiation coating and application and a radiant heat exchange apparatus using the same. The reinforcing thermal radiation coating comprises a reinforcing material component, a black material component and a binder. The reinforcing material component is silicon and/or boron. The coating can be applied to a surface of a metal material for use as a coating film. A radiant heat exchange apparatus comprises a first metal radiant plate and a heat exchange core plate formed by a second metal radiant plate and a heat transfer core plate. The coating can form a coating film on the surface of a metal material, which can greatly improve the absorptivity and emissivity of the surface of the metal material. The apparatus can be used for cooling and heating and can work for cooling in a hot and humid environment without dew condensation and also has a high cooling capacity.

Abstract: A radiation heat exchange device serving as a modular unit includes a first metal radiant plate, and a second metal radiant plate spaced apart from the first metal radiant plate to define a sub-near field gap between the first metal radiant plate and the second metal radiant. The first metal radiant plate is heat-exchanged with the second metal radiant plate through the gap to regulate a temperature of the first metal radiant plate for regulating a temperature of an environment to be temperature-regulated.

Abstract: The present invention provides a radiant air conditioning system for a heat-producing device (1), comprising a compressor (4), a condenser (5), an expansion valve (6), and at least one radiant panel evaporator (2) which are connected through a connecting pipe to form a recycling refrigerant loop, wherein each of the radiant panel evaporators comprises a refrigerant pipe (22) and a radiant panel (21) which exchanges heat with the refrigerant pipe (22). The radiant air conditioning system further comprises at least one heat transfer plate (3), configured to perform radiant heat transfer with the heat-producing device (1) and transmit an amount of absorbed heat to the radiant panel (21). The present invention improves heat transfer effect between the radiant panel (21) and the heat-producing device (1), and is particularly suitable for cooling a plurality of densely distributed heat-producing devices (1).
