摘要:
The refrigeration system of the invention comprises a vapour generator member (3) connected to a condenser (4) which is itself connected, by way of a pressure reduction valve (6), to an evaporator (5) connected to an absorber (2) which receives the liquid present in the lower zone of the generator (3) and from which liquid is fed to the upper zone of the generator (3), there being provided in the generator (3) a heat exchanger through which the engine cooling liquid flows, the generator member (3) and absorber member (2) containing a refrigerant fluid and an absorbent fluid, the absorbent fluid being able to absorb or dissolve the refrigerant fluid, which can itself be distilled or separated from the absorbent fluid by the addition of heat which is supplied to the generator (3) by the heat exchanger present in it, and be condensed and vaporised under the temperature and pressure conditions prevailing in the condenser (4) and evaporator (5) respectively.
摘要:
A system (10) for controlling refrigerant flow in an air conditioning system employing an electrically operated valve (24) for controlling flow of refrigerant from the condenser (18) to the evaporator (30). Separate thermistors (42, 54) sense the temperature of the refrigerant entering and discharging from the evaporator. A comparison of the sensed temperatures is used to modify the control signal to the valve for maintaining proper refrigerant flow to the evaporator.
摘要:
A refrigeration apparatus for a transport container has a partition (7) to divide the interior of a box (1), which is mounted on the front wall of a container, into two compartments (150, 19). In one (150) of the compartments is disposed a refrigeration assembly (200) including an evaporator (25), an evaporator fan (24), a condenser (27), a condenser fan (28) and a refrigerant compressor (29), in the other compartment (19) a common mount (30) is disposed on which a generator assembly (201) including an engine (35), an engine radiator (31), a radiator fan (32) and a generator (33) in in-line relation is mounted in such a manner that the generator assembly (20) may be installed into or removed from the box (1) as one unit. The refrigeration assembly (200) and the generator assembly (201) are thermally isolated from each other by the partition (7), so that exhausted warm air from one assembly does not heat the other assembly.

@ An orifice tube for use as an expansion va!ve in an automotive air conditioning system includes a cylindrical annular mass of porous material (32) having a cavity (31) extending coaxially through it. The orifice tube provides a variable volume of refrigerant to the refrigeration circuit, controlled according to the load on the air conditioning system.
摘要:
A control system (11) for a continuously driven variable, displacement compressor (12) particularly useful in an automotive environment is shown. The control circuit con- trols fluid flow through a cooling or heating circuit (10) to prevent evaporator (26) freeze-up at low ambient temperatures, and does not require a clutch to control the compressor (12). Instead a valve (12) is used to regulate fluid flow and prevent freeze-up.
