There is disclosed an environmental control system for thermally conditioning air within an enclosed space, the system comprising: a refrigerant circuit having a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger. The system comprises an exhaust flowpath having a first inlet for receiving an exhaust flow of thermally conditioned air from the enclosed space and an outlet for discharging the exhaust flow to an external environment. A heat transfer section of the outdoor heat exchanger is located in the exhaust flowpath, wherein the exhaust flowpath is for directing the exhaust flow of thermally conditioned air through the heat transfer section of the outdoor heat exchanger.

There is disclosed an environmental control system for thermally conditioning air within an enclosed space comprising: a refrigerant circuit having a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger. The system further comprises an intake flowpath for directing an intake flow of fresh air to the enclosed space, wherein a heat-transfer section of the indoor heat exchanger is located within the intake flowpath to thermally condition the intake flow of fresh air before entering the enclosed space. The system further comprises an exhaust flowpath for directing an exhaust flow of thermally conditioned air to an external environment. A recovery heat exchanger is provided to transfer thermal energy between the exhaust flow and the intake flow at a location within the intake flowpath that is upstream of the heat-transfer section of the indoor heat exchanger.

A bus heating system and a method of controlling the same, is configured for controlling a water-heating-type main heater unit and a heat-pump-type auxiliary heater unit in conjunction with each other for heating an interior of a bus, improving the efficiency of operation of the main heater unit while reducing the number of switch operations. The bus heating system includes a water-heating-type main heater unit configured to heat an internal bottom area of the bus, a heat-pump-type auxiliary heater unit configured to heat an internal roof area of the bus, and a controller configured to control operations of the main heater unit and the auxiliary heater unit in conjunction with each other based on a set target internal temperature (T.sub.target), a measured outside air temperature (T.sub.outside), a measured internal temperature (T.sub.room), and a main-heater-unit refrigerant temperature (T.sub.refrigerants).

A roof structure for an agricultural vehicle includes an upper roof assembly and a lower roof assembly connectable to the upper roof assembly. The lower roof assembly or the upper roof assembly includes a ventilation opening for guiding air-conditioned air and a circulation opening for supplying recirculated air. An air-guiding element is arranged between the lower and upper roof assembly. The air-guiding element is further disposed at the circulation opening and the ventilation opening such that a region sealed in relation to an external environment is formed.

A roof module for a motor vehicle, in particular for a passenger car, the roof module comprising a roof skin disposed on a roof substructure and a sensor system comprising at least one sensor module having at least one environment sensor for detecting the vehicle environment. The roof skin covers an air-conditioning mechanism having a thermal channel arrangement via which a cooling and/or heating fluid flows to the sensor module and/or an electrical feature of the roof module.

A vehicle roof assembly includes a roof that defines an aperture. A heating, ventilation, and air conditioning assembly is selectively disposed within the aperture. The heating, ventilation, and air conditioning assembly includes a housing defining an interior. The housing defines an intake and a vent opening. The intake is defined on a first side of the housing. A fan is disposed within the interior on a second side of the housing. The second side opposes the first side. A duct is disposed within the interior. The duct extends between the first side and the second side of the housing. The duct fluidly couples the intake with the vent opening.

A vehicle air conditioning system includes: air conditioners provided to respectively correspond to air conditioning zones; and a cooler that cools a target equipment mounted on a vehicle. The cooler includes a cooling circuit through which a heat medium for exchanging heat with the target equipment flows. Of the plurality of air conditioners, the air conditioner that air-conditions a door side zone is a door side air conditioner and the air conditioner that air-conditions a panel side zone is a panel side air conditioner. An amount of heat absorbed from the heat medium during an equipment temperature control, in which cooling of the interior and temperature control of the target equipment are respectively performed by the air conditioners, is smaller in the door side air conditioner than in the panel side air conditioner.

A recreational vehicle air conditioner (RVAC) includes a ceiling-mount indoor panel positioned over an opening in the ceiling of a recreational vehicle and a control box assembly including a first box portion and a second box portion. The first box portion is positioned above the ceiling-mount indoor panel and the second box portion is pivotally connected to the first box portion with a hinge, such that it is pivotable between a closed configuration and an open configuration. The ceiling-mount indoor panel defines a control box recess that at least partially receives the second box portion when in the open configuration and a blank plate covers the control box recess when the second box portion is in the closed configuration.

The present invention relates to a device for fixing a pipe and an electric wire that fastenedly blocks a fastening hole formed on a vehicle roof by means of a first connection member adapted to pass the pipe therethrough and a second connection member adapted to pass the electric wire therethrough, thus reducing the number of fastening holes formed on the vehicle roof and achieving easy assembling. According to the present invention, the device includes: a first connection member having a first through hole adapted to pass the pipe therethrough and a hollow portion formed on a given region thereof; and a second connection member having a second through hole adapted to pass the electric wire therethrough, wherein the second connection member has the corresponding shape to the hollow portion in such a manner as to be integrally formed with the first connection member, so that the first connection member and the second connection member block a fastening hole formed on a given region of a vehicle.
