A method of defrosting a transcritical vapor compression system having a compressor for compressing a refrigerant, a first heat exchanger for cooling the refrigerant during a cooling mode, an expansion valve for decreasing the pressure of the refrigerant, and a second heat exchanger for cooling a space during the cooling mode. The method includes attaining a superheated refrigerant condition in a defrost mode of the transcritical vapor compression system and defrosting the second heat exchanger in the defrost mode by directing the superheated refrigerant to the second heat exchanger without bypassing the first heat exchanger.

Defrost for transcritical vapor compression system

A mass transit vehicle includes a frame and a cabin mounted to the frame. The cabin includes a roof and a passenger zone defining a passenger zone length. An air cleaning unit includes an air cleaner housing mounted to the roof. The air cleaning unit is operable to draw in air through an inlet, through an air cleaning device, and discharge a flow of cleaned air out of an outlet. An air conditioning unit includes an air conditioner housing separate from the air cleaner housing. The air conditioning unit is operable to draw in air through an inlet, through an air conditioning device, and discharge a flow of conditioned air out of an outlet. The outlet of the air conditioning device is in communication with a duct system to direct the flow of conditioned air to the cabin substantially evenly along the passenger zone length.

A display for supporting produce generating ethylene gas as the produce ripens includes a surface for supporting the produce, a blower positioned in communication with the produce to move a gas containing at least a portion of the ethylene gas from the produce and an ethylene scrubber positioned in communication with the produce and in a flow path of the gas. The ethylene scrubber removes the at least a portion of the ethylene from the gas. The display does not include a refrigeration system such that a life of the produce is lengthened without use of refrigeration.

Table with ethylene scrubber

A display table for supporting produce includes an enclosure, a table top defining an upper surface of the enclosure, a blower, an ethylene scrubber and an outlet. The table top is open to the atmosphere and configured to support the produce, and includes perforations. The blower is positioned in communication with the enclosure to create an underpressure that draws a gas into the enclosure through the perforations. The ethylene scrubber is positioned in communication with the enclosure and in a flow path of the gas, the ethylene scrubber being configured to remove at least a portion of ethylene from at least a portion of the gas. The outlet is located downstream of the ethylene scrubber for returning the gas from the enclosure to the atmosphere.

The method includes operating an HVAC unit for a test period in an automatic temperature control mode and measuring power consumed at one or more testing heat loads at one or more rotational speeds. The method further includes determining an association between the measured power consumed at the one or more testing heat loads and one or more tested bus engine speeds and calculating power consumed at the one or more testing heat loads at a plurality of profiled bus engine speeds based on the association, wherein the plurality of profiled bus engine speeds is derived from a bus road profile of known bus engine speeds at known time durations, with the known time durations summing to a time period. The method also includes calculating energy consumed at the one or more testing heat loads over the time period.

Fuel consumption measurement of bus HVAC units

A mass transit vehicle including a cabin mounted to a frame and including a roof and a passenger zone defining a passenger zone length, an air cleaning unit including an air cleaner housing mounted to the roof, an air cleaning device disposed within the housing, an inlet upstream of the air cleaning device, and an outlet downstream of the air cleaning device, and a duct system disposed within the cabin and extending substantially along the passenger zone length. The air cleaning unit is operable to draw in air through the inlet, through the air cleaning device, and discharge a flow of cleaned air out of the outlet, and the duct system is in fluid communication with the outlet and operable to receive the flow of cleaned air from the outlet and direct the flow of cleaned air to the cabin substantially evenly along the passenger zone length.

A tractor and trailer combination including a tractor having a tractor frame, a supply unit, a trailer coupling, a skid plate, and a first connector coupled to the tractor frame and coupled to the supply unit to receive at least one of high voltage electrical power and coolant from the supply unit. The combination also includes a trailer having a trailer frame, a tractor coupling rotatably connecting the trailer to the tractor, and a second connector coupled to the trailer and configured to provide the at least one of high voltage electrical power and coolant to the trailer. The combination further includes a conduit having a first end coupled to the first connector, a second end coupled to the second connector. The conduit flexes and is supported between the first and second ends by the skid plate throughout rotation of the trailer relative to the tractor.
