What is the reason that the compressor of...
First, the compressor load is too large, overcurrent operation. Maybe the factors are: cooling water temperature is too high, refrigerant charging too much or refrigeration system air and other non-condensable gases, resulting in a large compressor load, manifested as overcurrent, accompanied by ...Read more -
Factors of slow or no drop in cold storag...
1, refrigeration evaporator surface frost is too thick or too much dust accumulation, heat transfer effect is reduced Layer is too thick or too much dust caused. As most of the surface temperature of the refrigeration cold storage evaporator is below 0 ℃, and the relative high humidity of the war...Read more -
How to improve the service life of cold s...
Cold storage sealing parts maintenance, due to the assembly of cold storage is made of a number of pieces of insulation board spliced together, so there is a certain gap between the board and the board, the construction of these gaps will be sealed with a sealant, to prevent the entry of ai...Read more -
Refrigeration repair in the eight misunde...
Myth 1: not after routine inspection, only by guessing to repair Many refrigeration repair masters, see the refrigerator leakage, not after the pressurized directly add condenser net, time is not long to leak again, only to find that it is actually the freezer evaporator leakage. In fact, the com...Read more -
What is the effect of high condenser wate...
Affecting the operating efficiency of the whole machine The lower the condenser outlet temperature (or saturation temperature), the higher the overall operating efficiency of the system, so if the outlet temperature is too high, it will affect the operating efficiency of the whole machine. Surge ...Read more -
Air source heat pump winter frost prevent...
1. Strengthen the pipeline insulation effect pipeline warming is very important, the exposed water pipes in the external environment will cool down when the temperature drops. 2. Do not disconnect the unit, water system air source heat pump heating, water as the intermediate medium for heat trans...Read more -

Compressor oil return in two ways
Compressor oil return there are two ways: one is the oil separator oil return, the other is the return pipe oil return. Oil separator installed in the compressor exhaust line, generally can be separated from 50-95% of the running oil, back to the oil effect is good, fast, greatly reducing the a...Read more -
Four types of safety protection measures ...
The motor for refrigeration compressor, as the most important part of the chiller, occupies an important position in the after-sales maintenance of the chiller. And, the maintenance cost of chiller compressor is relatively high. In order to reduce the chiller maintenance cost, the chiller compres...Read more -
What are the effects and hazards of uneve...
Dispensing head if the distribution is uneven, will make some subway refrigerant too much, so that the evaporator frost results in incomplete evaporation, affecting the system refrigeration capacity decline, but also may cause suction with liquid. 1, from the point of view of how much shunt flow....Read more -
How to correctly adjust the temperature o...
The principle of commercial freezers is the compressor through the compression of refrigerant and produce a series of physical changes to achieve the effect of refrigeration, but it is also very susceptible to the influence of the external environment, especially in seasons with large temp...Read more -

1, the location of the unit should be avoided as much as possible close to the fire source and flammable materials. If you have to set up with the boiler and other heat generators, we must fully consider the impact of heat radiation. 2, the refrigeration unit placed in the ambient temperature sho...Read more
