Wide range of applications
Plate heat exchanger is a kind of energy-saving, compact heat exchange equipment. It is a common equipment in refrigeration technology. It can be used as heat exchanger equipment such as condenser, evaporator, regenerator and intercooler. Compared with the traditional shell and tube heat exchanger, the volume is only 1 / 3-1 / 6 of the shell and tube type, the weight is only 1 / 2-1 / 5 of the shell and tube type, and the required refrigerant charge is only The shell and tube type 1/7, the heat transfer efficiency is 2-5 times higher than that of the shell and tube heat exchanger. It has the advantages of energy saving, economy, compact structure and easy disassembly, and is widely used in the refrigeration industry.
New cooling requirements
With the continuous development of refrigeration technology, new requirements have been put forward for the use of refrigerants, such as carbon dioxide, hydroxide and other refrigerant refrigeration systems. Ruineng Haoyu always pays attention to the development of industry technology and continuously improves its products to suit them.
When the refrigerant is evaporated in the refrigeration plate heat exchanger, it is easy to achieve evaporation to a liquid-free level. Therefore, in most cases, the refrigeration system does not need to be provided with a gas-liquid separator, and it is extremely easy to achieve unitization, simple and convenient installation, maintenance and transportation Both can save costs and reduce costs.
Basic requirements for the use of heat exchangers in refrigeration equipment
1. For plate heat exchangers used in refrigeration equipment, due to the high pressure on the refrigerant side (about 25 bar high) and strong penetration force, high pressure resistant brazed plate heat exchangers specially produced for the refrigeration industry should be selected.
2. The heat transfer coefficient is an important index to measure the heat transfer efficiency of the heat exchanger. With the increase of the heat demand per unit volume of the refrigeration unit, the heat exchange area per unit volume of the plate heat exchanger for the refrigeration equipment has also increased accordingly. Water-cooled and glycol-cooled units use energy-saving compact stainless steel brazed plate heat exchangers, which greatly improve heat exchange efficiency compared to shell and tube types, but the scale rate is only 1/10 of that of shell and tube condensers.
