Abstract

The invention discloses a heat exchange tube for a falling film type heat exchanger, the falling film type heat exchanger and an air conditioner heat pump unit, and belongs to the technical field of air conditioner. A coating is arranged on the outer surface of the heat exchange tube, and the coating adopts low temperature lyophilic and high temperature lyophobic materials; the falling film type heat exchanger comprises the heat exchange tube, the falling film type air-conditioner heat pump unit comprises the falling film type heat exchanger. According to the heat exchange tube for the fallingfilm type heat exchanger and the falling film type heat exchanger, the problem that the heat exchange performance of the falling film type heat exchanger as an evaporator or a condenser is low can besolved, and the dual high efficiency of refrigeration and heating of the air-conditioner heat pump unit can be achieved by changing lyophilic characteristics on the outer surface of the heat exchangetube.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchange tube for a falling film heat exchanger, a falling film heat exchanger, and an air conditioner heat pump unit. Background technique [0002] The existing falling-film heat exchangers are only used as falling-film evaporators in general commercial air-conditioning cold water (heat pump) units, and the heat exchange tubes arranged inside are evaporation tubes. When the falling film heat exchanger is used in an air-conditioning heat pump unit, the falling film heat exchanger is used as an evaporator when cooling and a condenser when heating, which requires that the heat exchange tube must have both an evaporation tube and a condensation tube The following characteristics: When the falling film heat exchanger is used as an evaporator, its heat exchange tubes are required to have the characteristics of evaporation tubes, that is, the outer surface of the heat e...
