Film evaporation type condenser

Abstract

The invention relates to the technical field of cooling, in particular to a film evaporation type condenser in order to solve the problem that the cooling effect of an existing evaporation type condenser is poor. In order to achieve the purpose, the film evaporation type condenser comprises a box body and an evaporative condensation unit arranged in the box body; the box body is provided with a refrigerating agent inlet and a refrigerating agent outlet; and the evaporative condensation unit comprises a heat exchanger and evaporation film groups, the heat exchanger communicates with the refrigerating agent inlet and the refrigerating agent outlet to form a refrigerating agent channel, a cooling liquid channel is formed through the evaporation film groups and the outer surface of the heat exchanger in an enclosing mode, cooling liquid is stored in the cooling liquid channel, and the evaporation film groups are arranged to selectively allow water molecules to penetrate. According to the film evaporation type condenser, the evaporative condensation unit is arranged in the box body of the film evaporation type condenser, the heat transfer efficiency is high, the condensation effect is good, and running noise and pollution are obviously reduced.

Description

Technical field [0001] The invention relates to the technical field of cooling, in particular to a film evaporative condenser. Background technique [0002] The cooling tower is a device for cooling the condenser coil of the central air conditioner. It cools the condenser coil by cooling the cooling water circulating between the condenser coil and the cooling tower box. Commonly used cooling towers are open cooling towers and closed cooling towers. The working principle of an open cooling tower is: by spraying cooling water onto the cooling tower filler, through the contact of water and air, heat exchange is achieved, and then the airflow in the tower is driven by the fan to circulate, and the After the heat exchange, the hot air flow is brought out, so as to achieve the purpose of cooling the cooling water. The working principle of the closed cooling tower is: the self-circulating water in the tower is in contact with the circulating cooling water coil, and the heat of the coo...

Problems solved by technology

[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem of poor cooling effect of the existing evaporative condenser, the present invention provides a film evaporative condenser, the film evaporative condenser includes a box body And the evaporating and condensing unit arranged in the box, the said box is provided with a refrigerant inlet and a refrigerant outlet, the evaporating and condensing unit includes a heat exchanger and an evaporating film group, and the heat exchanger is respectively connected to the The refrigerant inlet is communicated with the refrigerant outlet to form a refrigerant channel, and the evaporation film group is surrounded by the outer surface of the heat exchanger to form a cooling liquid channel, and the cooling liquid is stored in the cooling liquid channel. The evaporation membrane group is set to selectively allow water molecules to pass through, and when the high-temperature gaseous refrigerant enters the refrigerant passage through the refrigerant inlet, the refrigerant and the cooling liquid in the cooling liquid passage are heated Exchange and condense into liquid refrigerant and flow out from the refrigerant outlet, part of the water molecules in the cooling liquid evaporate into the air after passing through the cooling liquid channel
