Power Options for Refrigeration Heating Circulators

Refrigeration heating circulator is a temperature control equipment widely used in scientific research, biology, physics, medicine, chemical industry and other fields. We have many product models, which can be selected according to different sizes, different functions, different environments, etc.

The refrigeration heating circulator is composed of compressors, condensers, expansion valves, heat exchangers, temperature controllers, circulating pumps, pre-cooling units, heating units, refrigeration units and other accessories. Each component has its own role and advantages.

For users who use refrigeration and heating circulators for the first time, they are often confused because of the type of wire they choose. If the wire is too large, it will cause economic waste, and if the wire is too small, there will be hidden dangers. Therefore, how to choose a suitable power cord is a problem for many users. issues of greater concern. Next, I will analyze the selection of the power cord of the refrigeration heating circulator with you.

1. The total power, that is, the sum of the heating power and the pumping power. Calculate the current required for actual operation through the heating power, and then convert it into the wire diameter (refer to the wire current carrying capacity comparison table). . Generally, the heating power and pump power of the equipment will be marked on the nameplate of each equipment, so users only need to refer to the nameplate.

2. The number of phases of the power line, that is, the cable of several lines is selected. This mainly depends on the control voltage inside the equipment. Most manufacturers use AC 220V or DC 24V as the control voltage, especially for the latter, a transformer will definitely be installed in the equipment. Therefore, choose a three-phase four-wire system (three live wires and one ground wire) when choosing a power cord. In addition, there are also control voltages that use AC 220V, but there is no transformer in the equipment. When choosing a power line, you need to choose a three-phase five-wire system (three live wires, one ground wire, and one neutral wire).

3. The impedance of the wire in the refrigeration and heating circulator is proportional to its length and inversely proportional to its wire diameter. Please pay special attention to the wire material and wire diameter of the input and output wires when using the power supply. In order to prevent the wire from overheating due to excessive current and cause accidents.
