Types of the heat pump heat exchanger
Plate heat exchanger
Plate heat exchangers have the advantage of small size and high heat transfer efficiency, and are often used in high-energy efficiency models. However, their internal flow channels are small, which can easily cause blockages when the water quality is poor. They are usually made of stainless steel material, and if water contains corrosive components such as acid or alkali, it can cause damage to the heat exchanger. Therefore, they are generally used for heat exchange in clean water quality.
High efficiency tube in shell heat exchanger
High efficiency tube in shell heat exchanger is heat exchanger in which ribbed cooper tubes wound around iron shell for heat exchange, its heat transfer efficiency is high, and because the diameter of the copper tube is much larger than that of the plate exchange channel, its flowability is better than that of the plate exchange channel, and there is basically no blockage in the channel. However, its material cannot be used for corrosive fluids, and due to its special structure, it is not suitable for refrigeration conditions. Therefore, it is usually used in heating based systems.
Tube in tube heat exchanger
Tube in tube heat exchanger adopts the form of large tube sleeve small tube, with refrigerant flowing through the small tube and water flowing through the large tube to complete heat exchange. Its pipe material can be made of stainless steel or copper, with a larger volume and lower heat transfer efficiency than plate heat exchanger and high-efficiency tank. It is generally used for models with large assembly space and low energy efficiency requirements.
Shell and tube heat exchanger
Shell and tube heat exchanger, also known as tube and tube heat exchanger. It is a partition type heat exchanger with the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; But with low heat transfer coefficient and large footprint. Generally used in large units.
Titanium heat exchanger
The titanium tube heat exchanger consists of titanium metal pipelines and a PVC shell. The refrigerant flows through the titanium tube, while water flows through the PVC shell. Due to the strong corrosion resistance of titanium and PVC, it can be used in water containing corrosive substances. At the same time, its water interface size is large, so it can pass through a large water flow rate. This characteristic makes it very suitable for heating in swimming pools or for special environments such as constant temperature in fish ponds.
