摘要:
A thermal energy storage system (TESS) that enables the discharge of refrigerated air for cooling cargo or passengers in large compartments, such as the trailer of a semi-truck, for a period of time well in excess of several hours. The TES system is able to provide refrigeration without operating a conventional VCC unit, the truck engine, or the TRU diesel APU engine during all or a significant portion of the period of the typical range of time that a 53 foot refrigerated the truck is traveling over the road. The TES system includes a phase change material (PCM) reservoir, a cooling system-to-WF heat exchanger in fluid communication with the PCM reservoir, and a PCM-to-target heat exchanger in fluid communication with the PCM reservoir. The PCM reservoir contains a phase change material, a working fluid (WF) and a working fluid-to-PCM heat exchanger.

An air-conditioning apparatus once transfers energy to a heat medium other than a refrigerant and introduces the heat medium to another refrigeration cycle to achieve safety improvement and high efficiency. An air-conditioning apparatus allows first heat exchangers related to heat medium to exchange heat between a first refrigerant (heat source side refrigerant) and a first heat medium and allows a second heat exchanger related to heat medium to exchange heat between the first heat medium and a second refrigerant (hot water supply side refrigerant), such that the first refrigerant and the second refrigerant are prevented from mixing with each other.

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.

A solar powered compressor and pump is disclosed having a trough-shaped parabolic reflector for heating a conduit of refrigerant as it passes through the system. The compressor/pump combination includes a lens that covers the reflector and insulates and protects the reflector from the elements while increasing the intensity of the sun's energy entering the reflector. The reflector converts the sun's energy into heat that superheats the refrigerant as it passes through the reflector, reducing or eliminating the amount of mechanical work that the system has to do to achieve the needed superheating stage.
