摘要： A closed loop system utilizing a solar refrigerant turbocharger and pump in conjunction with a solar collector to operate a heating and cooling system for a building by utilization of a renewable energy source. The liquid pump within the solar turbocharger is used to boost the refrigerant pressures into the solar collector, the refrigerant absorbs heat inside the solar collector and changes phase from a liquid to a vapor. The vapor is expanded across the turbine causing the turbine to spin. The ability of the refrigerant to change phase or flash from a liquid to a vapor is due to the solar energy that is transferred from evacuated tubes into the solar collector manifold and into the refrigerant. The gas is routed to the solar turbo pump turbine to drive the compressor and liquid pump. The resulting fluid gas leaving the turbine is routed to the condenser for normal operation.

摘要： Transforming any heat sources to electric power, comprising a closed-cycle charged refrigerant loop. Low-pressure refrigerant fluid is pumped at 10 to 15 degrees F. higher of the ambient temperature through a heat exchanger heated by the heat of the gas outlet from the expander then to the boiler (heat exchanger) to boil the refrigerant liquid into a high-pressure and high temperature superheated by a few deg. F. gas (depending on the kind of refrigerant). Heated/pressurized refrigerant gas is inlet into an expander to power an output shaft during the expansion of the pressurized to a cooled gas. Cooled gaseous refrigerant with still high temperature is inlet to small heat exchanger to heat up the pumped liquid refrigerant before inlet to the boiler. The lowered temperature gas is condensed in condenser to liquid at low pressure and 10 to 15 degrees F. higher of ambient temperature media, and recycled by a pump to the heat exchangers. The refrigerant gas mass flow pressure drop spins the expander shaft for direct mechanical power take-off, or coupling to a synchronous or inductive generator to produce electricity. The electricity can be used locally, stored or fed to the grid.

摘要： An evaporator which heats working fluid with high-temperature fluid to evaporate the working fluid includes: a working fluid channel which is arranged in a flow direction of the high temperature fluid and through which the working fluid flows; and a temperature sensor which is provided for the working fluid channel. A part of the working fluid channel is exposed to outside of a housing of the evaporator, and the temperature sensor is provided in the part of the working fluid channel exposed to the outside of the housing of the evaporator in a region other than an inlet of the working fluid channel into which the working fluid flows from the outside of the evaporator and other than an outlet of the working fluid channel through which the working fluid flows out of the evaporator. The output value of the temperature sensor is used to adjust the temperature of the working fluid in the evaporator.
