Abstract: A generator-heat pump composite device comprises an internal combustion engine, a transmission device, clutches, a heat pump and a generator, wherein the internal combustion engine is connected to the heat pump and the generator via the transmission device and the clutches, respectively. The fuel for the internal combustion engine may be natural gas or biogas, and the heat pump may be a mechanical vapor compression heat pump. When the internal combustion engine is in operation, the heat pump and/or the generator can be selectively driven by engagement or disengagement of the clutches, for selectively generating electricity and/or cold and heat.

Abstract: An energy regeneration system comprises a heat pump, a bioreactor, a combustor, and a temperature difference electricity generation device. The heat pump is provided for thermally regulating the bioreactor and can be used for air-condition, dehumidification, refrigeration, chilling, heating and/or supplying hot water for bath. The bioreactor accommodates an organic material. The organic material is converted into a biomass fuel and other materials by microbial action. The chemical energy of the biomass fuel is converted into a heat energy by the combustor for actuating the temperature difference electricity generation device, thereby generating electrical energy.

Abstract: A heating and cooling system includes a compressor for pumping a heat medium through a tubing device, a heat exchanger coupled to the compressor for receiving compressed heat medium from the compressor, a flowing control device coupled to the heat exchanger, another heat exchanger coupled to the flowing control device and arranged to have the flowing control device coupled between the heat exchangers, and an air conditioner coupled to the flowing control device. The flowing control device may selectively couple the heat exchangers to the air conditioner and to the compressor, or selectively couple the heat exchangers together and to selectively couple the air conditioner to the compressor.

Abstract: A heating and cooling system includes a compressor for pumping a heat medium through a tubing device, a primary heat exchanger coupled to the compressor, a control device coupled to the primary heat exchanger and coupled to a intermediate heat exchanger to control the intermediate heat exchanger either to dissipate heat or to absorb heat. Another control device is coupled to the intermediate heat exchanger and coupled to the compressor and a secondary heat exchanger, to control the heat medium from the intermediate heat exchanger either to flow through the secondary heat exchanger or to directly flow into the compressor without flowing through the secondary heat exchanger.

Abstract: The present invention relates to a dual phase condenser system, including an air-cooled portion, a water-air-cooled portion and a fan. The air-cooled portion can be further divided into two sectors, wherein the external air, drawn by the fan, passing through the second sector of the air-cooled portion first then to the water-air-cooled portion. The ability of air absorbing water vapor can be increased significantly in the water-air-cooled portion due to the increase of vapor pressure deficit (VPD) of the air passing through the air-cooled portion of the condenser. The dual phase condenser system of this invention is a 3-stage air-cooled condenser when shortage of water occurred. By separating gaseous and liquid refrigerants, the ability of removing thermal energy of the refrigerants can be increased. This invention required no extra fans, thus the EER can be increased when compared with the traditional one stage or patented two-stage air-cooled condenser.

Abstract: A pressure accumulator device for vapor compressed air conditioning or refrigeration equipment, comprises: an accumulator with its one end connected to refrigerant pipe at high pressure side as compressor, and with the other end connected to an inlet pipe of a condenser; a flow-rate control unit provided at the outlet of said accumulator, or in the condenser tube of said condenser characterized in that high pressure is maintained for refrigerant at high pressure side.

Abstract: A vapor compressed air conditioning or refrigeration equipment includes an accumulator connected between the high pressure side of the compressor and, the inlet of the condenser; a flow-rate control unit is provided at the outlet of the accumulator. Also provided is a dipped type heat exchanger device disposed at the high pressure side of the compressor and connected between the compressor and the condenser via refrigerant pipes and a submersible heat dissipated tube. The dipped type heat exchanger includes a container for storing a heat transfer medium for heat exchange with a waste heat recycled tube combined with the container in heat transfer relationship. The tube is disposed between the low-pressure side of the air conditioning equipment and the compressor, for the purpose of reducing the temperature of the heat transfer medium and thus reducing the temperature of the high temperature superheated refrigerant vapor within the submersible heat dissipated tube.
