In the compressor, the refrigeration oil lubricates and cools the bearing and rotor via the differential pressure of the system and inner oil circuit. During exhaust of the compressor, refrigeration oil will be discharged out of the compressor together with gassy refrigerant. If the refrigeration oil can not return to the compressor, the compressor will …

Water-cooled chiller is a kind of vapor compression refrigerator. It works by energizing the refrigerant vapor via the compressor so that the pressure and temperature increase. Then it is turned to liquid refrigerant of low pressure and temperature by condensing and throttling. When the water chiller is evaporated in the evaporator, it obtains heat from …

A water chiller is a device used to lower the temperature of water. Most chillers use refrigerant in a closed loop system to facilitate heat exchange from water where the refrigerant is then pumped to a location where the waste heat is transferred to the atmosphere. However, there are other method in performing this action. …
One of the new developments in industrial chillers is the use of air cooling rather than cooling water. In this case, the condenser has no cooling with hot air refrigerant, but uses cooling towers made of cooling water. This development allows for more than 15% and allows for a reduction in energy demand in the …

Stabilizing Temperatures: Hydroponics requires a stable temperature. These plants need to be watered at an optional temperature. Under high or low temperature, plants may die or even reduce production. This is the function of hydroponic refrigerator. Designed to take away excess heat-hydroponic refrigerator can effectively stabilize your greenhouse temperature. This makes it easy to provide …
At present, the design of variable volume chilled water system generally adopts primary and secondary double loop. However, this double-loop configuration will produce: the use of two pumps to increase equipment investment; The mixing of chilled water supply and return water affects the efficiency of chiller under partial load. When the actual demand conditions of …
Scemiconductor refrigeration, also known as thermoelectric refrigeration, is based on the Peltier effect of semiconductor thermoelectric materials directly into the electric energy into a temperature gradient of solid state active environmental protection refrigeration technology. Although the direct conversion of potential differences into temperature gradients was discovered by scientists in 1843, semiconductor thermoelectric devices were not …
Influence of Heat Pipe Semiconductor on Water Chiller Read More »
Preferential loading is desirable for systems that use heat recovery or free cooling to allow the equipment used in these schemes to remain more fully loaded. In a heat recovery system, a more heavily loaded heat recovery chiller produces more heat that can be recovered for the desired process. Similarly, if the condenser free cooling …
When we use the water chiller, we will certainly do some troubleshooting first, and then use it. But in the process of use, there will be a variety of problems need to be solved. Next, let’s talk about the influence of low pressure on the chiller. Cooling system leak There are leaks in the connecting …
