Abstract
Expandable shelters having a heating, ventilation, and air conditioning (HVAC) system arranged to receive outside air away from a mechanical compartment are disclosed. The expandable shelters may comprise an air inlet vent disposed in a front of the expandable shelter interconnected to an in-floor air duct arranged to draw outside air below an interior floor and exchange heat with the coolest area of the expandable shelter. By virtue of having an air inlet vent receive outside air from a location substantially away from the mechanical compartment and exchange heat with the coolest area of the expandable shelter, an environmental control unit (ECU), housed in the mechanical compartment, receives relatively cool outside air, keeping air temperatures inside the mechanical compartment below the upper operating limit of the ECU.
Claims18
A heating, ventilation, and air conditioning (HVAC) system, the HVAC system arranged in an enclosure, the HVAC system comprising:
- a mechanical compartment arranged in a back of the enclosure and housing an environmental control unit (ECU) of the heating, ventilation, and air conditioning (HVAC) system;
- an air inlet vent of the HVAC system disposed proximate to the bottom of the enclosure and in an exterior of a front of the enclosure to receive outside air;
- an in-floor air duct of the HVAC system interconnected to the air inlet and arranged to draw the received outside air from the front to the back and along the bottom of the enclosure, and to exchange heat with an interior of the enclosure;
- and
- wherein the enclosure includes at least one displaceable side arranged between the ECU and the air inlet vent, the at least one displaceable side being displaceable in order to expand the enclosure from a shipping position to a use position.
A heating, ventilation, and air conditioning (HVAC) system, the HVAC system comprising:
- in a shelter comprising an enclosure defining an interior and including a top, bottom, front, back, and two sides;
- a mechanical compartment arranged in the back of the enclosure and housing an environmental control unit (ECU) of a heating, ventilation, and air conditioning (HVAC) system;
- an air inlet vent of the HVAC system disposed proximate to the bottom of the enclosure and in an exterior of the front of the shelter to receive outside air;
- and
- an in-floor air duct of the HVAC system interconnected to the air inlet and arranged to draw the received outside air from the front to the back and along the bottom of the enclosure, and to exchange heat with the interior of the enclosure;
- wherein at least one of the sides being displaceable in order to expand the shelter from a shipping position to a use position;
- when the at least one displaceable side is in the shipping position, the at least one displaceable side is arranged in the interior of the enclosure above the in-floor air duct, and
- when the at least one displaceable side is in the use position, the at least one displaceable side is arranged out of the interior of the enclosure and away from the in-floor air duct.
A heating, ventilation, and air conditioning (HVAC) system for use in a shelter, comprising:
- an environmental control unit (ECU) housed in a mechanical compartment arranged in a back of the shelter opposite to a front of the shelter;
- and
- a duct system for supplying air to the ECU, the duct system comprising:
- an air inlet vent disposed in an exterior of the front of the shelter to receive outside air from a location substantially away from the mechanical compartment in the back of the shelter;
- an in-floor air duct arranged below a floor of an interior of the shelter, wherein the in-floor air duct is interconnected to the air inlet and arranged to draw the received outside air below the floor and to exchange heat with the interior of the shelter through the floor;
- the shelter further comprising a displaceable side displaceable to expand the shelter from a shipping position to a use position;
- wherein when the displaceable side is in the shipping position, the displaceable side is arranged in the interior of the shelter above the in-floor air duct arranged below the floor, and
- when the displaceable side is in the use position, the at least one displaceable side is arranged out of the interior of the shelter and away from the in-floor air duct arranged below the floor, and provides another interior in addition to the interior of the shelter.
