Description

[Detailed description of the invention] The present invention enables a compressor driven by a motor in a heat pump air conditioner to be driven by a gas engine that uses power gas, and the power gas heats a heat medium by utilizing solar heat. This enables the supply of high-temperature gas as a high-temperature gas, making it possible to perform solar heat shielding cycles, heat pump refrigeration cycles, and power gas generation power cycles using a single heat medium that circulates in a series of sealed pipes. In addition, the circulation drive means is simplified and the power source is saved.As shown in the illustrated embodiment, the motor 1
A compressor 5 is provided which is driven by one of the and gas engine 2 via changeover switches 3 and 4, respectively, and the discharge pipe 6 of the compressor 5 is connected to a heat collecting device A mainly consisting of a solar heat collector 7. A heat pump type air conditioner B consisting of a cooler 8, an expansion valve 9, and a heat exchanger 10 is connected to a branch introduction pipe 6, respectively.
a, 6b, and the lead-out pipe 1 from the heat collecting device A.
1 is connected to the gas inlet pipe 13 of the gas engine 2 through the power unit C, which has a heat storage device 12 as its main body, and the outlet pipe 14 from the air conditioner B is connected to the suction side of the compressor winding. It is characterized in that the pipe 15 is also connected to the suction side of the compressor 5.

In the figure, 16 indicates a blower for indoor air supply, and each device A, B
, C are provided with control valves to open and close the channels or adjust the flow rate according to the purpose of use.

Furthermore, the illustrated embodiment utilizes the power plant C and is equipped with hot water supply equipment, where 17 is a hot water tank, 18 is a wood pipe with a float valve, 19 is a known gas water heater, and 20 is a temperature control valve. show.

As mentioned above, this device is used by sealing Freon gas as a heat medium in a continuous sealed pipe.In the initial startup, the compressor 5 is driven by the motor 1, and the Freon gas is sent to the branch introduction pipes 6a and 6b. By sending the heat to the heat collector A and the air conditioner B, the air conditioner B performs cooling or heating. During this time, the Freon gas is heated by solar heat by the heat collector A, and the heat storage chamber 12 of the power plant C is filled with gas. After the temperature rises to the level required to drive the engine 2, the clutch 3 is disengaged and the drive of the compressor 5 by the motor 1 is switched to the drive by the gas engine 2 to continue the cooling and heating cycle, making use of solar heat. On unavoidable cloudy days, at sunset, and at night, the heat collector A is stopped and the compressor 5 is driven either by the motor 1 or by the gas engine 2 that utilizes the heat storage of the power unit C to achieve the desired air conditioning cycle. The control valves of each piping route are opened and closed to provide heating and cooling.

The hot water supply equipment uses solar heat to constantly provide hot water regardless of cooling or heating, and if solar heat cannot be used, a gas water heater 19 is used.

In this way, this device operates the gas engine 2 using the power gas obtained in the power unit C through heat storage by the heat collecting device A using solar heat, and uses this as the driving force to drive the compressor 5 in the air conditioner B from the drive by the motor 1. Since switching operation is possible, it is not only economical to save the power source, but also because the heat collector A, the air conditioner B, and the power unit C are connected through a series of sealed pipes, it is possible to use one for circulating the heat medium. Since the base compressor 5 is used, each cycle of heat collection, refrigeration, and power can be carried out separately, and by using Freon gas as a heat medium, it can be used in a well-known refrigeration cycle as well as a gas engine driven by heating using solar heat. This has the effect of providing an extremely economical device that can obtain high-temperature gas.
