ASHPs are considered the most advanced technology available for heating, AC, and hot water. ASHPs are electrically driven systems that use the refrigeration cycle to transfer heat from one place to another. Below are examples of how ASHP systems provide heating, air conditioning, and domestic hot water solutions.
Air Source Heat Pump (ASHP)
VRF Heat Pump Technology
Variable Refrigerant Flow (VRF) is the most widely used HVAC technology globally. VRF heat pumps are a single system that provides high efficiency heating, air conditioning, dehumidification and air filtration. Heat pumps are electrically driven and are the least expensive way to deliver heating and cooling.
Heating and Air Conditioning
VRF Heat Pump HVAC systems consist of many small zones with dedicated air handlers called an inside units, typically one for each room, and are connected to the outside units (condensers) via small diameter refrigeration piping. If required a “heat recovery” VRF heat pump systems can operate in heating and AC mode simultaneously

Micro zoning for individual control and comfort
Low maintenance, no tune ups
System modulates to meet actual demand at all times
No mechanical room
Carbon free on-site, eliminate CMA penalties
Whisper quiet operation
Improved occupant comfort
Superior controls, no BMS required
VRF Heat Pump Advantages
Air to Water VRF (DVM Chiller)
The DVM Chiller provides a hydronic solution for replacement and new design solutions. Like VRF outdoor units, the DVM Chiller can modulate its capacity depending on the requirements of the various zones, which saves energy and improves occupant comfort.
Great for retrofit projects, the DVM Chiller can replace cooling towers, chillers, and boiler plants to provide hydronic capacity to any type of indoor air handling equipment.
Combines VRF and Chiller Techologies
Commonly found in hotel rooms and apartments a conventional PTAC is similar to a through-wall AC unit, but has a heating component as well. A HP-PTAC uses cold climate heat pump technology in a similar through wall floor mounted console to provide high efficiency heating and AC. This technology is ideal for upgrading existing equipment to dramatically lower operating costs and provide a quiet and comfortable space. Ideal for phased retrofit projects.

Energy Recovery Ventilation (ERV)
Proper ventilation is critical in maintaining indoor air quality and achieving effective pathogen mitigation. Energy recovery ventilation is the energy recovery process in HVAC systems that exchanges the energy contained in exhausted air of a building and using it to treat (precondition) the incoming outdoor ventilation air.
How does a ERV work? ERVs are equipped with two fans, one that draws fresh air into the building one that blows stale air out. When these two airstreams pass through the ERV, a heat exchanger within the system transfers heat and moisture from one airstream to the other.
Domestic Hot Water (DHW)
Air source heat pumps offer commercial and industrial users an energy efficient means of heating domestic water to temperatures as high as 160°F. Designed to meet decarbonization requirements, air source heat pumps efficiently transfer atmospheric heat via a refrigeration cycle for domestic hot water use.
Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters. To move the heat, heat pumps work like a refrigerator in reverse.
