However, other important parameters to consider must be taken into account. When the environment has lower humidity and a sufficient amount of water, then a water-cooled chiller can offer considerable savings in electrical energy. Refrigerants used in chillers RefrigerantĬhiller with water-cooled condenser compared to air-cooled.ĭepending on the environmental conditions and the resources that exist, the most suitable chiller can be selected and the efficiency of an installation can be increased.įor example, in places with high humidity, the efficiency of an air-cooled condenser chiller approaches that of a water-cooled condenser chiller because the relative humidity is higher. The water returns from the application at a higher temperature and re-enters the chiller to cool down again.The water leaves the exchanger at a lower temperature, and is brought to the application by a hydraulic system always in a liquid state.The refrigerant must now pass through the expansion valve, to return to low pressure and temperature, and thus the cycle repeats.Due to the heat exchange with the environment, at the condenser outlet the refrigerant becomes liquid again but still at high pressure.The refrigerant leaves the evaporator to the compressor to raise the pressure and facilitate condensation.The water being in a single state decreases its temperature (loss of heat).This process occurs in the coolant at almost constant temperature, plus a small increase in temperature (overheating).The heat coming out of the water causes the refrigerant to change its state of saturated mixture (Saturated liquid plus saturated steam) to the state of Superheated Steam.This is due to the low temperature of the coolant at this point. The heat from the water is received in the evaporator of the chiller.Since the objective is to cool a flow of water, a hydraulic circuit is needed.The chiller has a mostly compression refrigeration cycle that allows it to cool water flows continuously to the required values ![]() Our online chiller training classes have simulators that allow studying the behavior of the chilled water plant, according to the thermal requirements of the application. Know the water treatment required by the facility. According to the local hydraulic resources, economic resources and space, the chiller condenser is selected.With the distribution, a balance of supply and return flows is made, to know the true capacity of the chiller that is needed, so as not to oversize the equipment.Value of each water flow and its respective temperature value, to project the distribution and the piping system.With the minimum required temperature value, the type of chiller that is needed must be classified.Value of the minimum required temperature.Table of models of the most recognized chiller manufacturers.įirst steps to select the chiller you need. Some of the main manufacturers of chillers, we can see them in the following table, Chiller Manufacturer Chiller with Coaxial Tube condenser in tube. Chiller with at least one inverter compressor.ġ. Chiller with constant compressor speed, 2. Chiller Ultra-low temperature industrial refrigeration: For ranges between -60 ° F and -112 ° F.Ĭhiller Classification Summary: Chiller ClassificationĪccording to the outlet temperature of the chiller water.ġ.Low Temperature Industrial Chiller: Generally between + 20 ° F and -59 ° F.Medium and low industrial chiller for values between +20 ° F and + 35 ° F.Conventional Chiller: For temperatures greater than 35 ° F generally for air conditioning and machine cooling applications.Chiller can be classified according to the temperature value that the water reaches. The chiller can be used to generate temperatures in the water, from 7 ° C to temperatures below 0 ° C, where the use of glycol is necessary, to avoid freezing. Generally the difference between the water temperature, between the outlet and inlet is 5 ° C 10 ° F. Ice water can be used to generate air conditioning, or to cool machines. The chiller is a machine that, through a refrigeration cycle, is used to constantly cool a flow of water.
