A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.

There is provided a hybrid type heating system capable of heating air and water together. As an embodiment, the present invention provides a technology of carrying out heating not using a battery in an electric vehicle, a technology of heating a battery so that performance of the battery does not decrease under a low outdoor temperature condition, and a technology of carrying out heating with not decreasing driving distance of the electric vehicle or increasing the driving distance of the electric vehicle.

The present invention relates to the field of refrigeration and heating technologies, and in particular to a mobile type cold and hot integrated apparatus realized by a compressor, a thick film heater and a water circulation way in a single sealed space without heat exchange of an outdoor machine. The apparatus comprises a shell body, as well as a water circulation cooling compressor refrigeration system and a water circulation thick film heating pipe heating system which are provided in the shell body; wherein the water circulation cooling compressor refrigeration system comprises a refrigeration heat-dissipation module, a water pump A, a water tank, a compressor and a heat-dissipation water tank, the water circulation thick film heating pipe heating system comprises a thick film heating pipe, as well as the water tank and the refrigeration heat-dissipation module which are shared with the water circulation cooling compressor refrigeration system.
