Air Source Heat Pump Desuperheater

Geothermal systems make hot water in both heating mode and air conditioning mode.

Air source heat pump desuperheater.

In this study an extensive analysis of a desuperheater des applied in a combined solar and air source heat pump ashp system for a residential low heating energy building 45 kw h m 2 a is carried out using the climatic conditions of graz. The system consists of a standard single speed air source heat pump sized to the heating load rather than the usual smaller summer cooling load. The desuperheater is part of the geothermal heat pump s domestic hot water generating system hwg. By using a separate heat exchanger to utilize the high temperature of the discharge gas it is possible to heat water to a higher temperature than would be possible in a condenser see figure 10 6.

Desuperheating is the process of preheating your domestic hot water using discharge gas while in heating mode. It is merely a pump and a heat exchanger that is plumbed in such a way so as to carry the waste heat away from the refrigeration cycle and into your water heater. The heat pump system uses r410a as refrigerant and has a heating capacity of 4 9 kw a 12w35. The heat pump is connected to a large heavily insulated tank of water that the heat pump heats or cools depending on the season of the year.

This unit has no output while in cooling mode. Ac series desuperheater heat recovery unit for domestic hot water from air conditioning and refrigeration systems up to 200 tons ac series mechanically cleanable commercial desuperheaters recycle rejected heat from your air conditioning or refrigeration system and use it to heat water or other fluids. In this study an extensive analysis of a desuperheater des applied in a combined solar and air source heat pump ashp system for a residential low heating energy building 45 kwh m a is carried out using the climatic conditions of graz. Desuperheater units are located between the compressor and condenser to utilize the high temperature energy of the superheated refrigerant gas.

The hot water generating component of a geothermal system is called a desuperheater. Heat pumps reduce hot water costs through a component called a desuperheater. A desuperheater is a secondary heat exchanger that is part of your geothermal heat pump system and only operates when your system is running.
