The present invention provides a construction machine, which includes a cabin in which a driver is seated, the construction machine including a ventilated seat having fans, an air conditioning device configured to adjust an internal temperature of the cabin, and ducts extending from the air conditioning device and configured to guide an air flow, in which the ducts branches to include a first duct extending toward an upper side of the cabin, and a second duct extending toward a rear side of the ventilated seat. Therefore, it is possible to improve a cooling effect that the driver actually feels.

Disclosed is a rear air conditioner for a vehicle, which can improve the comfort of a rear seat in a vehicle by improving the temperature difference between a console vent and a B-pillar side while minimizing the increase in the temperature at the console vent side. The rear air conditioner for the vehicle is connected to a front air conditioner and supplies air conditioning airflow toward the rear seat of the vehicle, and comprises: a case of which one side is connected to the front air conditioner and the other side has a plurality of discharge ports for discharging the air into the interior of the vehicle; and an electric heater which is provided in the case and heats the air passing therethrough, wherein the electric heater is provided with a plurality of operating regions, of which at least one operates in linkage with an air conditioning mode.

A climate control system that includes a sensor configured to collect sensor signals from an interior of an enclosure and a climate control module configured to determine, based on the sensor signals, whether an air quality parameter is above or below an air quality threshold. When the air quality parameter is below the air quality threshold, the climate control system is configured to draw air from an exterior of the enclosure through a first filter and into the interior of the enclosure and draw the air from the interior of the enclosure through a second filter and return the air to the interior of the enclosure.

A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

An air conditioner for a vehicle has a housing. The housing defines an air passage therein, includes a suction port, and houses a blower fan. The blower fan draws an air from the suction port and discharges the air into the air passage. The housing includes a facing portion that faces an inlet defining member including an air inlet. The facing portion includes the suction port. The facing portion has a rib that protrudes from the facing portion toward the inlet defining member. The facing portion and the rib define at least a part of an air guiding passage that guides the air from the air inlet to the suction port.

A utility vehicle comprises a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame includes a front frame portion, a mid-frame portion, and a rear frame portion. The utility vehicle further comprises an attachment supported at the front frame portion. Additionally, the utility vehicle includes an operator area supported by the frame and including an operator seat and an adjacent passenger seat spaced apart from the operator seat. The operator seat and the passenger seat are in a side-by-side arrangement. The utility vehicle also comprises an auxiliary power assembly having an attachment shaft configured to be operably coupled to the attachment. The attachment shaft extends in a generally longitudinal direction of the utility vehicle and projects outwardly from the front frame portion.

A vehicle includes a vehicle body and an HVAC unit. The vehicle body has a first structure and a second structure that define a gap. The HVAC unit is fixed to the vehicle body and includes a motor and a case housing the motor. The case is disposed in the gap, abuts the first structure and the second structure, and reinforces the vehicle body between the first structure and the second structure.

A refrigeration system includes a primary evaporator that cooperates with a compressor, which compresses first refrigerant containing lubricant oil, to form a refrigeration cycle that circulates the first refrigerant. At the primary evaporator, the first refrigerant absorbs heat from second refrigerant and is thereby evaporated. The refrigeration system further includes a condenser, at which the second refrigerant releases heat to the first refrigerant and is thereby condensed. The refrigeration system also includes a secondary evaporator that cooperates with the condenser to form a refrigerant circulation circuit, in which the second refrigerant is circulated. At the secondary evaporator, the secondary evaporator absorbs heat from a primary cooling subject and is thereby evaporated. A refrigerant flow passage of the primary evaporator and a refrigerant flow passage of the condenser are independently formed, so that the refrigeration cycle and the refrigerant circulation circuit are independently formed.

A rear seat air regulating device includes a housing that has an air inlet formed at one side thereof, a front seat air passage, and a front seat air outlet formed at an upper portion thereof. The housing also has a rear seat air passage and a rear seat air outlet formed at a lower portion thereof. An evaporator and a heater are inside of the housing. A rear seat temperature door is mounted at the inlet of the heater in a manner of being rotated angularly to block or allow the air flowing to the heater. A rear seat mixing door is mounted where an outlet of the heater joins the rear seat air passage in a manner of being rotated angularly so that the mixing door performs opening and closing of the outlet of the heater and opening and closing of the rear seat air passage simultaneously.

A plurality of seating surface blowing ports is open at a seating surface of a seat. A first rear seat blowing port is provided on a rear side of the seat and opens toward a rear seat on the rear side of the seat. A single first duct is provided between the plurality of seating surface blowing ports, the first rear seat blowing port and the interior air conditioning unit, and guides the air conditioning wind from the interior air conditioning unit to the plurality of seating surface blowing ports and the first rear seat blowing port. The air conditioning wind that flows from the interior air conditioning unit through the first duct is blown out into a vehicle interior from the plurality of seating surface blowing ports and the first rear seat blowing port.
