The Effect Of Oil Temperature, Pressure, Level On Refrigeration Unit

The lubricating oil system is an indispensable part of the normal operation of all refrigeration units. It provides lubrication and cooling conditions for the moving parts of the refrigeration unit. Screw chillers and some piston chillers also need to use lubricating oil to control the energy adjustment device or the air extraction recovery device.

The Reasons for The Poor Refrigeration Effect of Refrigerating Equipment

In industrial production, there are too many applications of refrigeration equipment, and some equipment is out of repair and maintained not enough, so the refrigeration effect is often poor. The following are several reasons for the poor refrigeration effect of refrigeration machine.

The Commonly Used Refrigerants On Refrigeration Systems

Refrigerant R134a is currently one of the main refrigerating fluids that is internationally recognized as an alternative to R12. It is commonly used in automotive air-conditioning, commercial and industrial refrigeration systems, and as a foaming agent in the production of hard plastic insulation materials. It can also be used to configure other mixtures. Refrigerants, such as R404A and R407C, etc.

The Solutions to the Low Suction Pressure of Refrigerating Unit

Many users in the process of using the refrigeration unit, often find that the freezing effect is suddenly not as good as before or not frozen, how is this? We suppose that the refrigeration unit refrigeration is not good, means that the refrigeration unit suction pressure is too low.

Method for Refrigeration Leak Detection

When an oil stain is found somewhere in the system, this may be the point of leakage. There are major defects, unless the system suddenly breaks a large leakage point, and the system leakage is liquid colored medium, otherwise the visual detection of leakage cannot be located, because the leakage is usually very small, and many parts of the refrigeration system can hardly be seen.

A knowledge of Brushless DC electric motor

A brushless DC electric motor (BLDC motor or BL motor), also known as electronically commutated motor (ECM or EC motor) and synchronous DC motors, are synchronous motors powered by direct current (DC) electricity via an inverter or switching power supply which produces electricity in the form of alternating current (AC) to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor. This control system replaces the commutator (brushes) used in many conventional electric motors.

Seven Common Problems For Chiller Operation

When chiller operation, we may encounter this situation: the chiller current inlet water temperature is 24℃, and the outlet water temperature is 23℃. The temperature difference is too small to meet user needs. The main reasons for the small temperature difference between the inlet and outlet water are as follows:
