Benefits of technology

[0008]An advantage of the invention is that it enables a heat pump to heat a building adequately at low outside temperatures.
[0009]Another advantage is that the invention may use the free heat provided by solar panels to increase the efficiency of a heat pump.

Problems solved by technology

In an air-to-air heat pump system, when the ambient temperature is low, the system does not extract or produce the amount of heat that the system is capable of.

Embodiment Construction

[0018]Referring to FIG. 1, there is shown one embodiment of the air-to-air heat pump system 10 of the present invention. System 10 includes an indoor coil 12 and an outdoor coil 14. Refrigerant circulates, as indicated by arrows 16 in a closed circuit including coils 12, 14 and conduits 18, 20. System 10 also includes a thermal expansion valve 22 for heating with internal bypass, and a thermal expansion valve 24 for cooling with internal bypass.

[0019]A reversing valve 25 reverses the flow of refrigerant through the circuit depending on whether system 10 is operating in a heating mode or a cooling mode. With a counterclockwise circulation, as indicated by arrows 16, system 10 operates in a heating mode (i.e., heats the indoor side of the circuit). Conversely, with a clockwise circulation, system 10 operates in a cooling mode. System 10 further includes a filter drier 26 and an accumulator 28.

[0020]According to the invention, a solar heat exchanger 30 is in contact with, and may encir...

Abstract

A circuit board controller enables a solar hot water system to be used in conjunction with, and assist, a conventional heating system such as a furnace. If some heat is available from solar heating, then the solar heat is used for pre-heating so the conventional heating system does not have to perform as much work. If there is enough heat available from solar heating to provide all of the heat that is needed, then operation of the conventional heating system is locked out.

Description

RELATED APPLICATION[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 12 / 545,801, entitled “Solar Heat Exchanger”, and filed Aug. 21, 2009, which is hereby incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates generally to systems for the collection, storage and transfer of heat energy and, more particularly, to heat pump systems.SUMMARY OF THE INVENTION[0003]The present invention is directed to a solar heat exchanger for assisting an air-to-air heat pump system. An air-to-air heat pump loses its ability to produce heat when the ambient temperature is low. The solar heat exchanger of the invention enables warm solar solution to be introduced into thermal contact with the saturated vapor. This may allow the refrigerant to extract more heat at low ambient temperatures, so an air-to-air heat pump will be able to produce its designed heating ability at lower temperatures. Th...
