Choosing industrial refrigeration equipment for enterprises, primarily necessary to define what tasks you are going to put in front of him and try to take into account all the factors that will continue to affect the performance of the system cooling. Such options may be few, but you need to choose the most optimal.
To correctly determine the choice of refrigeration equipment must always take into account the system parameters such as:
- extreme heat
- the amount of heat in a time interval,
- Hydraulic resistance, as well as pre-agree on the heat dissipation and duplication systems.
As practice shows, in most cases, for a rational use of the equipment necessary to install more than one cooling system, and more. This is because the performance of the equipment at different times can be different: for example, a higher weekdays and weekends – lower. In such cases it is sufficient to install a small, which will increase the wear resistance of the cooling system and save on operating costs.
When choosing a pump to circulate the fluid, you will need to take into account the following factors: the diameter of the pipes, liquid lifting height and its distance from the energy source.
If the result of calculating the cost of refrigeration equipment coincides with the cost of downtime of the equipment, then we can consider the option of picking system spare equipment. In this case the two systems communicate with each other by the control unit, which in the case of an emergency or an unexpected stop of the main equipment will automatically turn spare.
Chiller Purchasing equipment with a powerful electric drive, you should consider that it has a limited number of starts per hour and running at the same time in the most unfavorable mode. Starting currents in this case is increased tenfold, and increases heat power cable is hundreds of times.
In contrast to the rated speed, increasing the current strength affects the torque, which increases at the start of dynamic impact on the shaft, bearings and couplings. Now, having seen the consequences of such a choice, you can imagine how many are able to serve in a similar refrigeration equipment operating conditions.
