Abstract: A supersonic cooling system operates by pumping liquid. Because supersonic cooling system pumps liquid, the compression system does not require the use a condenser. Compression system utilizes a compression wave. The evaporator of compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

Abstract: This temperature regulation apparatus comprises a heat pump (12) comprising a main compression circuit (14) for a refrigerant fluid taking heat from a cold source (16) and transferring it to a hot source (18). The cold source (16) comprises a first heat exchanger (24) for exchanging heat between the refrigerant fluid and a liquid coolant thermally coupling the main refrigerant circuit (14) to a first secondary coolant circuit (26). The first secondary circuit (26) has selective connection means (40, 52, 54) for selectively connecting it to the upstream and downstream ends (48A, 48B) of a “heater” branch (48) of a cooling liquid circuit (46) of an exothermal part of the vehicle. The exothermal part is preferably a heat engine of the vehicle. The invention is applicable to air conditioning a motor vehicle cabin.

Abstract: The device includes a heat pump integrating a refrigerant circuit taking calories from a cold source to transfer them towards a warm source. The device also includes a heat-conducting fluid/air thermal exchanger called external exchanger (30), located in the vehicle engine compartment (34), the heat-conducting fluid being either the refrigerant or a heat-conducting fluid in thermal exchange with the cold source refrigerant. The device also includes means of formation of an air flow, preferably a fan (40), circulating through the external exchanger (30) and called outlet air flow, directed from inside the engine compartment (34) to outside the vehicle. Preferably, the fan (40) shall be able to rotate in a first direction to form an air flow directed from outside the vehicle to inside the engine compartment (34) and called inlet air flow, and in a reverse direction to form the outlet air flow.

Abstract: A refrigeration and air-cycle air conditioning system is provided for a body defining interior space, preferably a stand alone refrigeration cabinet. The air conditioning system includes a unique combination of a compressor, intercooler, expander, motor and plenum to increase the performance of the system making it practical for use in commercial refrigeration.

Abstract: The apparatus comprises a heat pump (12) having a main refrigerant circuit (14) taking heat from a cold source (16) and transferring it to a hot source (18), and a cooling circuit (48) for cooling an exothermal part, such as an engine, the cooling circuit being connected to a cooling heat exchanger (50). The cold source (16) has a first refrigerant/coolant heat exchanger (24) thermally coupling the main circuit to a first secondary coolant circuit (26) capable of being selectively connected to an “outside” heat exchanger (30), to a “cold” heat exchanger (32), and to the cooling heat exchanger (50). The hot source (18) has a second refrigerant/coolant heat exchanger (34) thermally coupling the main circuit (14) to a second secondary coolant circuit (36) capable of being selectively connected to the outside heat exchanger (30), to a “hot” heat exchanger (39), and to the cooling heat exchanger (50). The invention is applicable to air conditioning a vehicle cabin.
