What is application of plate heat exchanger?
Plate heat exchanger is an efficient and compact heat exchange equipment, which is widely used in refrigeration system and is an indispensable equipment in refrigeration system. It can be used as condenser, evaporator, regenerator and intercooler etc. Thermal equipment, compared with the traditional shell and tube heat exchanger,
the volume is only shell type 1/3 to 1/6, the weight of only shell type 1/2 ~ 1/5, the required refrigerant charge It has the advantages of energy saving, economy, compact structure and convenient disassembly. It is widely used in the refrigeration industry. For example, the heat transfer efficiency is 2 to 5 times higher than that of the shell and tube heat exchanger. Chiller and air-cooled heat pump water chiller as evaporator, condenser, heat recovery heat exchanger (superheater), liquid subcooler, and screw compressor oil cooler and other heat transfer applications.
1, The basic requirements of plate heat exchangers for refrigeration equipment
(1) Plate heat exchangers for refrigeration equipment, due to high pressure on the refrigerant side (up to about 25bar), strong penetration, should be selected specifically for the refrigeration industry production of high pressure brazed plate heat exchangers.
(2) The heat transfer coefficient is an important index to measure the heat exchange efficiency of the heat exchanger. With the improvement of the energy requirement per unit volume of the refrigeration unit, the heat exchange area per unit volume of the plate heat exchanger for refrigeration equipment is also correspondingly increased.
The water-cooled and glycol-cooled units employ a compact stainless steel brazed plate heat exchanger in a university with a substantial increase in heat exchange efficiency over the shell and tube heat exchanger, with a structural ratio of only 1/10 of the shell and tube condenser.
2, As the evaporator plate heat exchanger In the air-cooled heat pump unit, the refrigeration cycle, the plate heat exchanger as an evaporator.
3, As a condenser plate heat exchanger Heat pump unit in the refrigeration cycle as a plate heat exchanger with evaporator in the heat pump cycle as a condenser.
4, Heat recovery unit with plate heat exchanger Heat recovery unit is the use of condensation heat will be tap water heating into domestic hot water that is the process of hot water, thus taking away the heat generated by the refrigeration system, which will directly meet the hot water tap water Into the heat recovery heat exchanger (also known as overheating cooler), the use of some of the compressor part of the exhaust heat of the latent heat of condensation to heat it, leaving the exhaust heat from the condenser into the atmosphere. A plate heat exchanger for heat recovery is installed between the condenser and the compressor.
