The water-to-water heat pump is an Axiom™ 5, 10 and 20 ton system. Similar to a small reverse cycle chiller, a water-to-water heat pump contains a source-side water-to-refrigerant heat exchanger, and a load-side water-to-refrigerant heat source for the water-to-water heat pump is typically connected.
Water Source Heat Pumps. A Trane Axiom™ water-source heat pump (WSHP) delivers high-performance heating and cooling with exceptional efficiency: up to 40 EER on select systems. Advanced technology makes a Trane Axiom water-source heat pump easy to operate and maintain, resulting in optimal comfort and long-lasting durability.

Given the constant rise in energy prices and the negative consequences the large scale exploitation of traditional energy sources (fossil fuels, coal) inflicts on the environment, the ‘business as usual’ approach we adopted as to the way we power our homes for the past years, has to be reconsidered.
A water-source heat pump rejects or extracts heat to and from a water loop instead of from ambient air. A unitary air conditioner or heat pump with more than one factory-made assembly (e.g., indoor and outdoor units) is commonly called a split system.
General Design Considerations Types of Unitary Equipment Equipment and System Standards. In addition to year-round temperature control, unitary heat pumps add the energy-saving advantage of individual room or zone control. Factory-packaged and refrigerant based, these units are available in a number of application categories which include.
Not only do Daikin heat pumps offer economical heating of residential and commercial settings, they can also provide a total solution for domestic heating and hot water supply.
Connecting solar collectors to the heat pump system further increases efficiency and savings. Unique designs, including inverter-driven compressors and natural.
A unitary lineup is offered in the North American residential market. Unitary products provide high performance and energy efficiency at an affordable price. Advanced design including the condenser fan system provides quiet operation to both interior and exterior environments.
Both cooling only and heat pump type heating/cooling units are. In support of the High Efficiency Commercial Air Conditioning and Heat Pump Initiative, CEE publishes the CEE Commercial Unitary AC and HP Specification, which provides high efficiency performance specifications for the following types of equipment.
air- water, and evaporatively-cooled unitary air conditioners; air- and water-source unitary heat pumps. Download York Heat Pump PDF manuals. User manuals, York Heat pump Operating guides and Service manuals. There are two classes of water-source Heat Pumps.
Water-to-air heat pumps provide space conditioning primarily by the use of an indoor air heat exchange coil. Water-to-air models may also provide domestic water heating and hydronic space heating by using desuperheater and/or demand water heating functions.
The system also rejects heat to a second water loop that is serviced by a cooling tower or a geothermal ground source or pond. This product line can be configured as a chiller, a heating unit or as a heat pump that can provide cold water in the summer and heated water in the winter.

YORK ® heat pumps are designed, engineered and assembled in the United States and come standard with industry-leading warranties, so you can be confident a YORK ® system will provide your family with comfort, energy savings and lasting performance for years to come.
Contact your local YORK dealer. Contact your local YORK dealer. The air is pulled through the heat exchanger by a fan whenever the heat pump is on. The air to water heat pump heat exchanger has a refrigerant running through it which is able to absorb heat at a low temperature.
Air to water heat pumps can heat your house or building even when it is as low as degrees outside.

A Heat Pump Using Carbon Dioxide as the Refrigerant. 7 Tips to Get More from Mini-Split Heat Pumps in Colder Climates. A heat pump “pumps” heat from a low to a higher temperature level. The heat raised is transferred to the water distribution system (under floor heating, low temperature radiators and/or fan coil units for low temperature heating systems and high temperature radiators for high temperature heating systems) in the home via a heat exchanger.

Heat Pump Pros. There are a lot of benefits to using a heat pump vs air conditioners. • Because heat pumps remove heat from a cool area and transfer it to a warm area, they can be used to both heat and cool and so can be useful all year long.
• In the summer, heat pumps will move the warm air outside, leaving your house cool. In the winter. An air source heat pump (ASHP) is a system that transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another.
They can be used as a space heater or cooler, and are sometimes called "reverse. Basic Heat Pump Maintenance - A good heat pump maintenance plan will include a thorough check of the refrigeration system, the electrical system, the heat pump controls, and the air filter system of the heat pump maintenance is as important as maintenance on your vehicle.
If we fail to take good care of our vehicle then it is more prone to breakdowns whereas. These other types include (by ascending efficiency) air-to-air air conditioners and heat pumps, water-to-air heat pumps, and chillers.
The unitary HVAC load shapes developed in this project further support program administrator calculations of savings in the forward capacity markets. Nordic ® R Series Commercial Water to Air Heat Pump.
The R Series Commercial water to air heat pump is designed for use in apartment or condo buildings, where each unit has their own heat pump to centrally heat and cool their space.

The higher the COP of a heat pump, the greater the percentage of "free" heat in its total output. Water-to-water heat pumps connected to geothermal sources and low temperature (95¯¯F) loads typically have COPs in the range of to Technology improvements continue to produce incremental gains in COP.
HSPF is specifically used to measure the efficiency of air source heat pumps. The efficiency of air conditioners is often rated by the HSPF as defined by the Air Conditioning, Heating, and Refrigeration Institute in its standard / Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.Lennox XP17 Heat Pump.

The CHW/HW for the radiant panels is provided by a water-to-water heat pump. The DOAS has a water-to-air heat pump (with a HW reheat coil tied to the radiant HW loop).
Both heat pumps are tied to a condenser loop that rejects/extracts heats from a nearby river via a heat.
