摘要:
A Mechanical Ventilation Heat Recovery (MVHR) system for a building having a roof with at least two pitched slopes facing in different directions, the MVHR system comprising a Heat Recovery Unit (HRU) for receiving and exchanging heat between a flow of ambient air from outside the building and a flow of building air from within the building, the HRU being connected by fluid flow conduits to first and second ports located on different pitched slopes, in which a flow diverter is provided in the conduits between the HRU and the ports, the flow diverter being switchable between a first state in which ambient air flows from the first port to the HRU and into the building and building air flows from the HRU to the second port to be exhausted from the building, and a second state in which ambient air flows from the second port to the HRU and into the building and building air flows from the HRU to the first port to be exhausted from the building. The system can be combined with photovoltaic solar cells and/or an air source heat pump and/or a ground source heat pump system.

An air handler building structure is disclosed, which includes a floor, a plurality of lateral walls, a roof and one or more openings located either on the roof or on at least one of the lateral walls. The lateral walls include a lower and an upper lateral walls opposing to each other having different respective heights determined in accordance with a ratio. The roof has a pitch consistent with die ratio associated with the lower and upper lateral walls. The shape of the building structure allows air within the building structure to rise via natural convection. In addition, a first dimension along a first direction defined between the lower and upper lateral walls relative to a second dimension along a second direction perpendicular to the first direction is such that the building structure provides access to outside natural air via one or more openings on the lower lateral wall.

Systems and methods for controlling conditions in an enclosed space, such as a data center, or for providing cooling to a device, can include using a Liquid-to-Air Membrane Energy Exchanger (LAMEE) as an evaporative cooler. The LAMEE or exchanger can cool water to the outdoor air wet bulb temperature in a cooling system disposed outside of the enclosed space or device. The reduced-temperature water can be delivered to the enclosed space or device or can cool a coolant that is delivered to the enclosed space or device. The air in the enclosed space, or one or more components in the enclosed space, can be cooled by delivering the reduced- temperature water or coolant to the enclosed space, rather than moving the supply air from the enclosed space to the cooling system. In an example, the cooling system can include one or more cooling coils, upstream or downstream of the LAMEE.

The instruction device according to the present invention is used in an air conditioning system. In a case where evaluation information concerning comfort of an air environment of an indoor space for person(s) in the indoor space corresponds to discomfort and a difference between first data on the air environment of the indoor space and second data on an air environment of an outdoor space is not less than a prescribed value, the instruction device creates setting information to use only a first air conditioning device for causing movement of air between the indoor and outdoor spaces when determining that the comfort can be improved by the first air conditioning device, and creates setting information to use a second air conditioning device for controlling the air environment of the indoor space by consuming energy resource when determining that the comfort cannot be improved by the first air conditioning device.
