The choice of refrigerant pump affects the following factors: the distance from the industrial chiller to the point of consumption, the diameter of the pipe, and the need to lift this very fluid at any height.
The system can also be a complete refrigeration unit, which will be in stock. If the production downtime cost and equipment costs are equivalent, it is recommended to do. In this case, the installer places the electronic control unit in an electronic control unit that automatically adjusts the operation of the refrigerator so that the time is the same.
Unacceptable matching industrial chiller with powerful electric drive capacity exceeds the required level. why? Because some customers are buying "future" cooling equipment, hopefully they will need large capacity after some time. For example, a refrigerator that purchases very high cooling capacity, hopefully in the future will be additional equipment that requires water cooling. It seems this calculation is correct. By purchasing a more powerful industrial refrigerator today, it is certain that tomorrow it has enough room for new equipment. However, there is a problem. Refrigerators often turn on / off if the thermal stresses on the refrigeration equipment are greater respectively. There are limits to the number of starts per hour for electrically powered powerful devices. What caused it? At the same time, whenever the equipment is operating in the most unfavorable state: the starting current is more than 10 times the rated value, and accordingly, the heating cable can be up to 100 times higher than when operating at nominal conditions. Increasing the current at start-up results in higher torque, resulting in a dynamic effect on the clutch, bearing and shaft for each shot. As a result, even the most reliable industrial cooling equipment can not serve you and its operating costs can grow several times.
The best level of industrial refrigeration is achieved when work is done throughout the entire shift. This requires selecting the refrigeration unit so that it barely covers the maximum heat flux. In addition to precisely selecting the productivity of the device, different ways to reduce the transmit frequency can also be considered. One way to do this is to increase the thermal inertia of the circulating water system by introducing a system capacity, which will act as a "cold battery" and will increase the time between starts.
When industrial refrigerators select heat from coolant, it is necessary to consume the heat somewhere, which is easier to say "throw." The amount of heat released can be very large depending on the capacity of the installation itself.
