Unit Ventilators

Heat Pumps

Daikin's unit ventilators can be configured to operate with various heat pump technologies, perfectly aligning with electrification initiatives. These options include:

• Self-Contained Air Source Heat Pump (ASHP): ASHP units extract heat from outdoor air, even in cool temperatures, and transfer it indoors to warm the space.
• Water Source Heat Pump (WSHP): WSHP systems extract heat from a nearby water source and transfer it indoors for heating. They can also reverse the process to remove heat from the building for cooling.
• Ground Source Heat Pump (GSHP): GSHP systems utilize the earth's natural temperature as a heat source or heat sink.

Electric Heat

Daikin’s unit ventilators allow for electric heat configuration for buildings without an existing hydronic heating infrastructure or transitioning from traditional boiler systems. With a simple design and lack of complex plumbing requirements for hot water loops, these units provide an ideal solution for renovation and retrofit applications.

Steam Heating Systems

For older buildings with existing steam heating systems, Daikin offers unit ventilators configurable with steam coils. This allows for precise temperature control in individual spaces. To ensure optimal performance, steam coils are:

• Double tube, steam distributing freeze-resistant type
• Include a factory-installed pressure equalizing device (vacuum breaker) to prevent condensate retention

Direct Expansion (DX) Heat

Unit ventilators can be equipped with direct expansion (DX) cooling coils and thermal expansion valves for buildings with existing steam heating systems or those lacking a dedicated hot water loop.

DX heating systems offer faster response times than hot water systems due to the direct transfer of heat from the refrigerant.
