How should I protect my air conditioning unit from freezing in the winter?
Winter is not only our own need to prevent cold and warm, as refrigeration people, we also have to "care and maintenance" of our refrigeration equipment, especially in the cold north, pay attention to the central air conditioning also need to do a good job of cold measures, especially shopping malls, manufacturing enterprises, hotels and other large-scale field of commercial central air conditioning need to prevent freezing, then how to p
Refrigeration compressor equipment procurement "three taboos" and "four than"!
I. Three taboos 1, avoid the "figure cheap" Whether at home and abroad or large enterprises, small businesses, it is almost impossible to sell refrigeration compressors at a low price, if the lower the price pressure, then the enterprise in the refrigeration compressor equipment, accessories and parts of the choice will be the worse, because the en
Refrigeration compressor liquid strike, overheating cause analysis
Many low-temperature chiller units use original imported scroll compressors, so many customers also call them scroll chillers. Chillers in the operation process, often due to various problems resulting in compressor burnout, liquid strike and other phenomena. Low-temperature chiller compressor liquid strike situation can lead to scroll disk damage, liquid strike failure phenomenon is generally
Refrigeration equipment 7 kinds of throttle mechanism, you know which?
Throttling mechanism has the liquid refrigerant throttling pressure reduction, to ensure that the pressure difference between the condenser and evaporator, so that the evaporator is also too refrigerant in the requirements of the low pressure evaporation, to achieve the purpose of refrigeration; regulate the refrigerant flow rate supplied to the evaporator to adapt to the evaporator's heat load changes.

Cold storage equipment common 16 faults and treatment methods
1, refrigerant leakage Failure Analysis] Refrigerant leakage in the system, the cooling capacity is insufficient, suction and discharge pressure is low, the expansion valve can be heard than usual much larger than the intermittent "squeak" airflow sound. The evaporator does not hang frost or hang a small amount of floating frost, if you adjust the expansion valve hole, suction pressure is stil
How to accurately select power cords for refrigeration equipment?
The installation of refrigeration equipment is a very strict requirements of the work, the installation will affect the work of the machine to a large extent, therefore, in the installation of the time, the contractor needs to choose the right power cord. But the choice of the power cord is actually a study, choose a large will cause economic waste, choose a small and there will be security risks, how big to be both safe and economical? T
A must-know classic primer for refrigeration people!
First, the basic knowledge of the central air conditioning 1, what is the refrigerant, its working principle? In the cooled object and the environmental medium between the transfer of heat, and ultimately the heat from the cooled object to the environmental medium of the refrigeration machine in the refrigeration cycle of the working material. The
Refrigeration system in the event of blockage failure how to solve the problem
Refrigeration system if a blockage occurs in the fault how to solve, is a lot of users concerned about the problem, the refrigeration system blockage is mainly produced by the throttle valve oil blockage, ice blockage or dirty blockage, or filter drier dirty blockage. Today, we will introduce you to the reasons and solutions for the blockage of the system in detail. 1, the oil plug failure
Glycol chiller refrigeration principle
Glycol chiller, as the name suggests, is a chiller that uses glycol as the carrier refrigerant of the chiller. Sometimes the cold-carrying liquid needs to go below 0°C. If the cold-carrying liquid with water will freeze, adding some antifreeze liquid can avoid freezing, and ethylene glycol can be antifreeze. In the all-air system, when the outdoor
Refrigeration unit cooling tower two kinds of cleaning program reference
Cooling tower exposed for many years, the fan adsorption is very strong, so that a large number of sediment, dirt into the tower, a long time running will make the cooling tower slowly reduce the ability to dissipate heat, water distribution holes are easy to block, sediment and dirt is also very easy to enter the cooling water system to go, will directly affect the cooling water system of the normal refrigeration. In order to prevent the
How to choose an air conditioning unit? What are the common air conditioning units?
I. Water-cooled chiller Water-cooled chiller belongs to the central air-conditioning system in the refrigeration unit part of the refrigerant for the water, known as chiller, and the condenser cooling for the use of room temperature water heat transfer cooling to achieve. Therefore, it is called water-cooled units, and water-cooled units relative to the air-cooled units, air-cooled units of th
How to build a cold storage can be more energy efficient Cold storage to reduce energy consumption
As we all know, the electricity consumption of cold storage is very high, especially for large and medium-sized cold storage. Therefore, in the daily cold storage project, many enterprises will consider the energy-saving of cold storage, and hope that the energy efficiency ratio of cold storage can reach high utilization rate, so as to save electricity expenses. First, accurate and timely adjust
Do you know these common refrigeration and air conditioning terms?
1, work, energy, horsepower, cooling capacity 1 joule (j) = 1 watt (w) x 1 second (s) (1) Energy unit: National system: j, kj; English system: cal, kcal 1 j = 0.2388 cal (2) Power units:
Refrigeration repair commissioning , first understand these basic knowledge ....
Condensing Temperature The condensing temperature of the compressor system is the temperature at which the refrigerant condenses in the condenser, and the refrigerant vapor pressure corresponding to this temperature is the condensing pressure. Condensing temperature is one of the main operating parameters in the refrigeration cycle, for the actual
Analysis of common causes of chiller failure
Chiller is a kind of energy-saving machine that achieves refrigeration effect through vapor compression or absorption cycle. Chiller is fully known as cooling water circulator, also called chiller, etc. At present, the market is mainly air-cooled chiller, water-cooled chiller, screw chiller. First, the classification of water chillers
How to break through the development of screw units?
1.Intelligent unit: from doubt to popularization Many years ago, the intelligent unit was introduced, customers have doubts, with the increase in labor costs, as well as enter the enterprise more and more, product stability, price loosening, the intelligent unit began to "walk into the people's common home". At present, the production of intelligen
What are the effects of oil temperature, oil pressure, and oil level on a refrigeration unit?
The lubricating oil system is an indispensable part of the normal operation of all refrigeration units, which provides lubrication and cooling conditions for the moving parts of the refrigeration units. Screw chillers and some piston chillers also need to utilize lubricating oil to control energy regulation devices or pumping recovery devices. At present, piston chillers store the lubricating
Refrigeration system operation testing and common faults
I. Pre-operation check Refrigeration equipment before the start of the inspection is related to the normal operation of refrigeration equipment is a key link, so the operation and maintenance personnel should be particularly careful when checking: 1, whether the power supply in the range of 380V ± 5%.
