Water Cooled Heat Pump Operation

Water source heat pump unit operation a water source heat pump is a mechanical reverse cycle device that is used to transfer heat from one medium to another.

Water cooled heat pump operation.

The water supply may be a. I recently ran an analysis of two heat pumps. The chiller condenser water heat is recovered instead of being rejected to the outside and used as a heat source for a water source heat pump system serving the perimeter spaces. High efficiency self contained units are available in a variety of sizes and configurations and can be placed in virtually any location within a building.

Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days. Definition of a heat pump ashrae handbook 2008. We cover air to air h. How heat pumps work in this video we ll be discussing how heat pumps work starting from the basics to help you learn hvac engineering.

The unit s compact footprint allows for easy installation where space is a concern. A geothermal heat pump with an assumed seasonal average cop of 4 0 and a cold climate air to water heat pump with a seasonal average cop of 2 5. Evaporatively cooled chillers offer higher efficiencies than air cooled chillers but lower than water cooled chillers. Water cooled chillers are typically intended for indoor installation and operation and are cooled by a separate condenser water loop and connected to outdoor cooling towers to expel heat to the atmosphere.

A heat pump extracts heat from a source and transfers it to a sink at a higher temperature in engineering the term heat pump is generally reserved for equipment that heats for beneficial purposes rather than that which removes heat for cooling only 3 capacity is determined. A water source heat pump extracts heat from the water when in the heating mode and rejects heat to the water when in the cooling mode. The closed water loop provides condenser water to the interior zone cooling units picking up the heat normally rejected to a cooling tower and transferring it as.
