Heating and Cooling
All condo units in the Marquess of Lorne development will be equipped with a Mitsubishi heat pump, a Renewaire Indoor Energy Recovery Ventilator (ERV) and electric baseboard heaters for those days when it is too cold to use the heat pump. In addition, all two bedroom units will have a fireplace. Hot water for the building will be provided by two high efficiency natural gas hot water heaters located in the parkade mechanical room.
Heat pumps can be thought of as refrigerators that can work in reverse. While air conditioners and freezers are familiar examples of heat pumps, the term "heat pump" is more general and applies to many heating, ventilating, and air conditioning (HVAC) devices used for space heating or space cooling. When a heat pump is used for heating, it employs the same basic refrigeration-type cycle used by an air conditioner or a refrigerator, but in the opposite direction – releasing heat into the conditioned space rather than the surrounding environment. In this use, heat pumps generally draw heat from the cooler external air or from the ground. In heating mode, heat pumps are three to four times more effective at heating than simple electrical resistance heaters using the same amount of electricity.
Energy recovery ventilation (ERV) is the energy recovery process of exchanging the energy contained in normally exhausted building or space air and using it to treat (precondition) the incoming outdoor ventilation air in residential and commercial HVAC systems. During the warmer seasons, the system pre-cools and dehumidifies while humidifying and pre-heating in the cooler seasons.
