Abstract:
Provided is a hot water supply device associated with a heat pump. The hot water supply device uses a cascade heat pump including a two-stage cycle to perform a hot water supply operation. Refrigerants flowing through a heat side heat exchanger and a usage side heat exchanger are heat-exchanged with water. Thus, the hot water supply operation is continuously performed without a defrosting operation, and a hot water supply performance and a heating performance can be improved.

Abstract:
An energy efficient heat pump system capable of operating in extreme low and high temperature environments. The heat pump system includes an evaporator, a heater operatively associated with the evaporator, compressor and condenser. In an exemplary embodiment, the heat pump system may further include a plasma pulse-spark system to facilitate removal of scale deposits. The heater heats an environmental medium prior to the environmental medium exchanging energy with a refrigerant located in an evaporator coil of the evaporator in order to maintain a predetermined minimum temperature differential between the environmental medium when it contacts the evaporator coil and the refrigerant when located in the evaporator coil. The system allows efficient operation at low temperatures.
Abstract:
The invention relates to a heat pump system for heating or cooling a building and/or for supplying hot or cold water. The heat pump system consists of a closed frame which is provided on the underside with a heat exchanger anchored in the ground or in surface water in a position of use. The frame is provided with a recess in which a heat pump can be placed. Halves of rapid-action couplings are received in the recess, and the heat pump is likewise provided with halves of rapid-action couplings so that the heat pump can be easily slid into the recess.
