An air conditioning module having all the necessary components for conditioning air, is so sized and arranged that, when placed in an internal compartment of a bus, has its respective openings register with an existing return air duct and a supply air duct on the bus. The compartments and modules are so arranged that they can be paired in back-to-back relationship, with one on each said of a longitudinal center line of the bus. Each of the modules has an intermediate partition dividing the module into an upper evaporator section and a lower condensing section. A mixer flap is placed in an intermediate position with respect to the partition such that its position may be selectively adjusted to thereby vary the amount of fresh air and return air that is passed through the condenser coil and evaporator coil, respectively.

An evaporator unit for use in the air conditioning system of a mass transit vehicle that includes a housing mounted inside the air conditioned section of the vehicle having a return air inlet connected to a supply air outlet by a flow passage. The evaporator coil of the air conditioner is mounted in the flow passage to cool the air moving through the passage. A heater coil is mounted behind the evaporator coil to selectively heat the air moving through the passage. A dehumidifying coil is mounted in front of the evaporator coil that utilizes ambient air to dehumidify the indoor air when the ambient air temperature is at a temperature below that at which the air conditioner cannot reliably operate.

A cooling system for a heat source includes a heat source loop, a refrigerant loop, and a controller. The heat source loop provides a closed fluid path for a process fluid and fluidly connects a valve, a bypass leg and/or a heat exchange leg having a heat exchanger, and a pump. The process fluid is disposed within a portion of the loop and is subject to heat transfer from the heat source. The valve is disposed downstream of the heat source portion of the loop, wherein the valve is selectively operable to direct process fluid to the bypass leg and/or the heat exchanger leg. The refrigerant loop provides a closed fluid path for a fluid refrigerant and fluidly connects the heat exchanger, a refrigerant compressor, a refrigerant condenser, and a refrigerant regulator. The controller is in communication with the valve and is adapted to control the valve to regulate an amount of process fluid entering the bypass leg and the heat exchanger leg.

A refrigerant flow metering device which varies the expansion area of the device in response to the differential pressure between refrigerant in the high and low pressure sides of a refrigerant system. The expansion device includes a housing with a flow passage extending therethrough which is divided into a high pressure portion and low pressure portion by a partition. The partition has a flow metering port which extends therethrough and interconnects the high and low pressure portions. An elongated member extends through the flow metering port and cooperates with the flow metering port to define a refrigerant flow metering passageway therebetween. The elongated member is configured to vary the cross-sectional area of the flow metering passage in relation to the position of the elongated member to the flow metering port. Means are provided for supporting the elongated member within the flow passage and for controlling the axial position of the elongated member within the passage in response to the differential pressure between refrigerant in the high pressure portion and the low pressure portion.

A refrigeration expansion valve meters the flow of refrigerant therethrough through a flexible orifice that varies in cross sectional area as a function of the pressure differential across the valve. The flexible orifice is provided in a tubular elastomeric element that is supported at opposite ends by rigid support means. A rigid spacer means is provided for engaging the support means to prevent the pressure differential of the refrigeration system from exerting an axial force on the flexible flow metering element.

A refrigerant expansion device for use in a refrigeration system includes a body having a flow passage extending therethrough. A piston having a flow metering port therethrough is moveably mounted within the flow passage. A flow metering rod is supported within the housing and extends through the flow metering port. The flow metering rod and the flow metering port cooperate to define a flow metering passage between them. The flow metering rod is configured so that the cross sectional area of the metering passage varies relative to the axial position of the piston with respect to the rod. The piston is spring biased and the piston moves relative to the rod as a function of the pressure differential across the piston. The cross sectional area of the flow metering rod is configured to define a defrost metering zone which cooperates with the metering port to provide a defrost flow metering passage, at pressure differentials lower than the normal pressure differential for cooling operation of a system in which the device is to be installed. The defrost metering passage is substantially larger than the flow metering passage required for normal cooling operation of the refrigeration system.

A heat exchanger of the plate fin and tube type which comprises two longitudinally extending sections. The two sections each have a planar cross section and form a continuous length. The sections are bent relative to one another with the planar cross sections of the two sections forming an angular relationship therebetween in two different planes. In a preferred embodiment, a further bend is made thereby forming a third longitudinally extending section.
