Water Cooled Chiller Environmental Requirements
- Aug 16, 2017 -

The system consists of a compressor, a condenser, an expansion valve, Water Cooled Chiller and an evaporator, which are connected by piping into a sealed system. The refrigerant liquid in the low temperature and low pressure in the evaporator is in heat exchange with the object to be cooled to absorb the heat of the object to be cooled and vaporized, and the generated low pressure steam is sucked by the compressor and compressed to be discharged at a high pressure. Water Cooled Chiller The high-pressure gaseous refrigerant discharged from the compressor enters the condenser and is cooled by normal cooling water or air to condense into a high-pressure liquid. Water Cooled Chiller The high-pressure liquid flows through the expansion valve and becomes a low-pressure low-temperature gas and liquid two-phase mixture into the evaporator. The liquid refrigerant evaporates and evaporates in the evaporator, Water Cooled Chiller and the resulting low-pressure gas is sucked again by the compressor. So again and again, and constantly circulate.

Chillers: This system consists of outdoor host and indoor end devices, through the outdoor host to provide air conditioning cold / hot water, from the water pipe system to the indoor end of the device, Water Cooled Chiller water and air at the end of the indoor heat exchange to eliminate the room cold / heat load. Is a type of air conditioning system that collects cold / heat but concentrates the handling of the room loads.

The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. The liquid refrigerant is completely evaporated into a gaseous state and is sucked and compressed by the compressor. The gaseous refrigerant absorbs heat through the condenser, condenses into a liquid, Water Cooled Chiller passes through a thermal expansion valve Or capillary) after the throttle into low-temperature low-pressure refrigerant into the evaporator to complete the refrigerant cycle process.

Chiller selection should take full account of the local energy conditions, equipment prices, Water Cooled Chiller unit energy consumption, operation and management, unit life, but also take into account environmental requirements. In all places, the energy conditions of each project are not the same, Water Cooled Chiller and even vary widely, including the energy policy around, energy prices, energy supply reliability. In determining the air conditioning chillers, the technical and economic comparisons must be made on the basis of the specific energy background. Select air conditioning chillers, it is necessary to consider the equipment performance, but also consider the price of equipment. Water Cooled Chiller Chiller water consumption is to determine the air conditioning program to consider an important factor, in addition to air conditioning chillers also require easy operation and management, Water Cooled Chiller failure rate is small, long service life.

Chillers of the energy regulation performance than its full load under the COP value of more practical significance, most of the buildings only a few hours a year air conditioning full load, 70% of the time in the 5% to 60% of the load range, So we really care about the chillers in the vast majority of the actual load conditions under the performance factor, so the chiller performance adjustment is the engineering design needs to focus on the aspects.

In the operation of the chiller, the evaporation pressure, the evaporation temperature and the coolant water into the evaporator heat and close relationship. When the heat load is large, the evaporator's water return temperature rises, causing the evaporation temperature to rise and the corresponding evaporation pressure is also increased. On the contrary, when the heat load is reduced, Water Cooled Chiller the cooling water return temperature of the refrigerant is lowered, Water Cooled Chiller and the evaporation temperature and the evaporation pressure are reduced. The actual heat load in the operation of the chiller is constantly changing with the load of the workshop. Water Cooled Chiller In order to adapt the working performance of the unit to this change, Water Cooled Chiller the automatic control is used to adjust the energy of the unit to maintain the relative stability of the evaporation pressure and temperature.
