Various residential, commercial, and industrial facilities utilize HVAC chiller units to meet temperature requirements for several processes and applications. These units come in a variety of specifications to meet customer requirements. This article overviews HVAC chiller units in contrast with industrial chillers.
Chiller systems for the HVAC industry leverage the conventional refrigeration cycle to provide cooling for residential, commercial, and industrial applications. These chillers commonly utilize water, oils, and other industry-certified fluids as refrigerants. Comprising a compressor, condenser, thermal expansion valve (TXV), evaporator, stabilization assembly, and reservoir, an HVAC chiller begins the cooling process with high-pressure compression of the refrigerant to a superheated gas. The system then ensures the gas transfer to the condenser, cooling it to a warm liquid for transmission to the evaporator via the TXV. Finally, the evaporator converts the liquid to a cool, dry gas for industrial, commercial, and residential cooling.
While HVAC and industrial chillers are primarily ideal for cooling purposes, these systems differ in several ways. Customers primarily utilize HVAC chiller units for air conditioning and comfort cooling. However, these units can offer some advanced features key to industrial chillers at additional costs. These two chiller systems are different in the following aspects:
While HVAC chiller suppliers do not provide components such as reservoirs, pumping systems, and controls, industrial chiller units come with these components, significantly minimizing installation costs. Similarly, unlike industrial chillers, which come from the factory pre-piped with water-regulating valves, HVAC chiller manufacturers include these valves in the unit packaging with the option of pre-piping them at extra costs. While industrial chiller manufacturers conventionally offer a labor warranty, HVAC chiller manufacturers do not.
In light of water and refrigeration circuits, these systems offer dependent and independent water circuits and refrigeration circuits, respectively, making them susceptible to total shutdowns. On the other hand, industrial chiller units come with independent evaporators, making them operational at 50% capacity in the event of system failures.
HVAC chiller systems come in several condenser cooling methods, including air-cooled, water-cooled, and remote air or split systems. Moreover, they come in several specifications, offer several features, and are ideal for several applications.
Cooling capacity, fluid discharge temperature, and compressor motor horsepower are some top specifications for HVAC chillers. Cooling capacity includes the overall capacity of the chiller to eliminate heat from the process fluid, commonly measured in kilowatts or tons of refrigeration. While the fluid discharge temperature is the temperature requirement of fluid discharge, the compressor motor horsepower represents a nominal value for approximately specifying chillers.
HVAC chiller manufacturers incorporate several features into the design of their units to meet several application requirements. Some of these features include the microprocessor controls for precise programming of chiller performance, emergency alarms to indicate emergency events, such as low coolant levels and overtemperature, and integral pumps for pumping capacity. Moreover, outdoor chillers, typically rooftop-mounted, offer advanced cooling capabilities, and modular systems are ideal for several applications due to their capabilities for several building parts.
