Main Components of Heater Chiller Temperature Controller
The internal work of the heater chiller temperature controller is mainly composed of three parts: the compressor, the expansion valve, and the heat exchanger. The expansion valve, also known as the throttle valve, is usually installed between the liquid storage tank and the evaporator. Next, let’s talk about the important components of the heater chiller temperature controller and understand their features and functions.
1. Heat exchanger: A heat exchanger refers to a heat exchange device between two fluids of different temperatures. Heat exchanger is an important equipment for heat exchange and transfer in chemical production. In the heat exchange process, there are often some highly corrosive and oxidizing materials, so the requirements for the corrosion resistance of the materials used in the heat exchanger are relatively high. Non-metallic materials such as graphite, ceramics and glass, and metal materials such as stainless steel, titanium, tantalum and zirconium can be used. However, materials such as graphite, ceramics, and glass have disadvantages such as fragility, bulkiness, and poor thermal conductivity. Heat exchangers made of rare metals such as titanium, tantalum, and zirconium are too expensive, and stainless steel is difficult to withstand various corrosive media, which will cause intergranular corrosion.
2. Condenser: The industrial steam is introduced into the condenser tube bundle by the demister. The refrigerant vapor condenses on the pipe, and the discharged heat flows through the pipe through the cooling water, condenses the refrigerant, and collects at the bottom of the condenser at a trough.
3. Evaporator: The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate, forming a certain temperature difference between the refrigerant and the water. The liquid refrigerant evaporates into a gas, which is absorbed and compressed by the compressor (increase in pressure and temperature). The air refrigerant absorbs heat through the condenser (air-cooled/water-cooled), condenses into a liquid, and becomes a low-temperature and low-pressure refrigerant after being throttled by a thermal expansion valve (or capillary) and enters the evaporator.
4. Compressor: After accumulatively running for 1000 hours, check the compressor. First of all, check whether the lubricating oil is normal, secondly, whether the current of the compressor is normal when it is running, and finally check whether there is any abnormal sound when the compressor is running.
