A natural air conditioning system for a car is characterized in a heat energy accumulator, a car battery, a cooler, and a solar collector panel connected to compressor, fan and condenser assembly, expansion valve, and fan and evaporator assembly that are included in a typical car air conditioning system. When the car air conditioning system is in operation, a part of cold energy produced in the system is stored in the heat energy accumulator and the cooler. And, when the car air conditioning system is in an off state, power provided by the solar collector panel or the car battery drives the fan associated with the evaporator and cold energy previously stored in the heat storage accumulator is released to keep an indoor space of the car at a comfortable temperature. Cold energy stored in the cooler also enables the cooler to serve as a spare car refrigerator.

1. A natural air conditioning system for a car comprising a heat energy accumulator, a cooler, and a solar collector panel and/or a car battery connected to a compressor, a first fan associated with a condenser, an expansion valve, and a second fan associated with an evaporator that are included in a general car air conditioning system; a refrigerant provided in said natural air conditioning system being compressed by said compressor and then flowing through said condenser and said expansion valve with a part of said refrigerant flowing through said heat energy accumulator or said cooler, so that surplus cold energy is stored in said heat energy accumulator or said cooler before said a part of refrigerant flows back to said compressor to complete one cycle of flow in said natural air conditioning system, wherein said heat energy accumulator includes an energy storage chamber and a loop-type heat pipe associated with said energy storage chamber;said energy storage chamber being filed with a phase change medium that stores and releases cold energy through freezing into and melting from a solid phase, and being externally coated with an insulation material to prevent heat loss; and said energy storage chamber being provided at a top with an upper lid for replenishing said energy storage chamber with said phase change medium via said upper lid, and at a bottom with a drain hold for draining said phase change medium; and said loop-type heat pipe being divided into three main parts, namely, first, second and third parts; said first part being a set of paralleled pipes vertically disposed inside said energy storage chamber and having a plurality of densely distributed short fins provided on an outer surface thereof to extend in a direction perpendicularly to said paralleled pipes; said second part including a vertical low-temperature heat pipe and a vertical high-temperature heat pipe located outside said energy storage chamber for conducting heat exchange with low-temperature and high-temperature driving fluids, respectively; both said low-temperature and said high-temperature heat pipes being provided on inner and outer surfaces with a plurality of fins or helically grooved tubes; and said third part including an upper horizontal pipe and a lower horizontal pipe for connecting said vertical paralleled pipes inside said energy storage chamber to said vertical low-temperature and said high-temperature heat pipes outside said energy storage chamber so as to form said loop-type heat pipe; said loop-type heat pipe being filled with an adequate amount of appropriate working fluid, and having a pressure-limiting safety compartment located outside said energy storage chamber to communicate with said vertical low-temperature heat pipe; and said vertical low-temperature heat pipe and said vertical high-temperature heat pipe of said loop-type heat pipe being provided around an outer surface with flowing passages, that is, a low-temperature heat exchanger and a high-temperature heat exchanger, respectively, through which driving fluids of low-temperature and of high-temperature flowing to conduct heat exchange with said vertical low-temperature and said vertical high-temperature heat pipes, respectively; and said low-temperature and said high-temperature heat exchangers being externally coated with an insulation material.
