1, heat exchanger classification
By structure:
◆ Finned tube type (refrigerant/air, refrigerant/air)
◆ Shell and tube type (refrigerant/refrigerant)
◆ Tube type (refrigerant/refrigerant)
◆ Plate (refrigerant/refrigerant)
◆ Cooling tower (water/air)
According to the form of heat transfer medium:
◆ Refrigerant/air - finned tube type
◆ Refrigerant/carrier refrigerant (shell and tube type/sleeve type/plate type)
◆ Water/air (Cooling tower)
By function:
◆ Evaporator
◆ Condenser
◆ End coil
◆ Cooling Tower
1. Air-cooled/air-cooled condenser
A cold condenser is a heat exchanger that uses air as a cooling medium and is mainly used to convert high-temperature gas or steam into a liquid. This kind of condenser usually consists of a long tube with a heat sink with excellent heat conduction performance attached to it to improve the heat dissipation efficiency. The purpose of the heat sink is to increase the heat dissipation area, and speed up the air convection through the fan to take away the heat.
2, horizontal shell and tube condenser
There is a partition in the end cover to separate the heat exchange tube into several processes, mostly using an even number of processes, so that the nozzle is on the same side, this article from the refrigeration encyclopedia public number hvacrbk. Refrigerant through the shell process, that is, R22 condenses outside the pipe, the upper part of the air, from the lower part of the discharge. Cooling water piping process; Down in, up out. Water flows against R22. High heat transfer coefficient (compared with air cooling), less cooling water consumption (compared with vertical), widely used.
