Chiller: What is it? How Does It Work? Types & Uses

Chiller: What is it? How Does It Work? Types & Uses

A chiller unit is a cooling mechanism designed to produce fluids that can lower temperatures by removing heat from the fluid. The type and use of a chiller depends on the required temperature and kind of refrigerant, which can be a liquid or a gas.

A relatively new type of heat pump for residential systems is the absorption heat pump (AHP), also called a gas-fired heat pump. Absorption heat pumps use heat or thermal energy as their energy source, and can be driven with a wide variety of heat sources such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water, and therefore are …

As the chilled water load decreases, the chiller and cooling tower work will reduce but the condenser pump work will remain the same. At some part load operating point, the savings from the smaller condenser pump will offset the chiller penalty and for all operating points below this, the increased condenser range will save energy.

Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor temperatures, this system utilizes the cool outdoor air …

It has 2 working modes: 1. “Dry” Mode. During most of the year, the unit works as a conventional dry-cooler, with no water consumption and the heat transported by the water is dissipated in the ambient air by convection of the air forced by the fans. 2. “Adiabatic” Mode. During high ambient temperature periods and only when the dry mode is not sufficient to maintain the outlet water ...

Jul 11, 2019 The rate of cooling of a chiller is dependent on the amount of refrigerant circulating through its compressor. Valve stems sometimes vibrate loose and will result in refrigerant leaks. Refrigerant leaks from the compressor or the introduction of moisture into the system can also impact the cooling capacity of the chiller.

The cooling tower is widely used in power generation plants. Especially, the steam power plants use the cooling tower even more. In steam power plants when the heat is converted to mechanical energy, all of the heat can’t be converted to mechanical work and here the cooling tower is used. Heating, ventilation and air conditioning

This reduces the efficiency of the chiller, wastes energy, and increases cost. The chiller will consume 2.5–3.5% more energy for each degree increase in the condenser temperature. For example, if a chiller uses $20,000 of electricity each year, it will cost an additional $500–700 per year for every degree increase in condenser temperature.
