These energy-efficient HVAC solutions are designed to enhance the versatility and flexibility of climate control within large industrial spaces, providing cost-effective and efficient cooling and heating solutions for businesses.

VRF/VRV Systems

VRF/VRV systems are highly efficient HVAC systems used in industrial settings for heating, ventilation, and air conditioning. These systems can be either heat pump or heat recovery systems, providing simultaneous high-efficiency heating and cooling.

VRF systems have the capacity for more than a single evaporator and do not require ducts for air distribution, distinguishing them from other HVAC systems. This makes them energy-efficient and cost-effective choices for commercial property managers seeking sustainable and effective industrial air conditioning solutions.

Rooftop and Split Units

Rooftop and split units are common types of industrial HVAC systems used in commercial buildings. Split systems are typically more cost-effective than rooftop units, making them a popular choice.

Moreover, split systems offer energy-efficient air conditioning options, which can contribute to significant cost savings for commercial property managers. These systems consist of an outdoor unit with a compressor and condenser coil, as well as an indoor unit containing the evaporator coil and air handler.

They provide efficient heating and cooling solutions for large spaces while being relatively easy to maintain.

Direct Expansion

Direct Expansion, also known as DX, utilizes the compressor, evaporator coil, metering device, and condenser coil to expand the HVAC system. The DX system market is growing due to the rising demand for energy-efficient and environmentally friendly HVAC systems.

Engineers are exploring the selection of Direct Expansion (DX) refrigerant-to-air evaporator coils for industrial HVAC systems when applied with condensing units.
