The invention relates to a heating and/or cooling device comprising a filmable to scatter infrared light in order to diffuse heat. The film comprises a planar heating element comprising a connector that is electrically connected to conductive tracks placed on said film and connectable to a thermostat, The film receives a conductive ink that is deposited on the film in particular by screen-printing or inkjet printing, the film being able to scatter infrared light in order to diffuse heat or cold over bodies or objects placed in proximity thereto without diffusing heat or cold into the space. The film is arranged to receive sensors and/or RFID means.

In a first aspect, a system for heating, cooling, or both heating and cooling a room is disclosed. The system includes a panel with a first, second, and third wall. The second wall is disposed between the first and third walls and separated by a plurality of partitions. The partitions create a first and second row of elongated channels. Each channel in the first row is bounded on two sides by two partitions and on two other sides by the first and second walls. Each channel in the second row is bounded on two sides by two partitions and on two other sides by the second and third walls. The first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through. The fluid layer is in thermal communication with the room. The second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.

Purified air is provided, having a TVOC content of from less than 5 ppb to about 500 ppb, a Biologicals content of from less than 1 CFU/M.sup.3 to 150 CFU/M.sup.3 and a Particulate content of from about 1,000 0.3 μm particles per ft.sup.3 to about 50,000 0.3 μm particles per ft.sup.3, or from about 600 0.5 μm particles per ft.sup.3 to about 500,000 0.5 μm particles per ft.sup.3.

A radiant air conditioning system for controlling comfortable and healthy indoor environment based on infrared sensing technology is disclosed, which comprises air source heat pump outdoor unit, plate evaporator, circulating water pump, etc. Accurate control of air humidity by installing an indoor dehumidification terminal can reduce the surface temperature of radiant cooling terminal and increase the installed area, which will significantly improve the radiant heat exchange between the terminal surface and the human body surface. Infrared sensor technology, which is adopted to obtain the number of indoor occupants and the required outdoor air flow rate, is integrated with a decoupling control of the indoor humidity and air freshness for the accurate control of outdoor air flow rate, and then the supply outdoor air temperature and humidity are regulated for the accurate control of indoor health level.

Air conditioning systems for cooling multiple-zone spaces, each zone having a thermostat, where each of multiple pump modules delivers chilled water to chilled beams in a plurality of zones and a chilled-water distribution system circulates chilled water through a chilled-water distribution loop to the multiple pump modules. Current dew points are determined in zones that call for cooling, and temperature of chilled water delivered to the chilled beams is maintained for each pump module at least a predetermined temperature differential above the highest dew point within the zones served by that pump module. Each zone has a zone control valve to shut off flow to that zone. Serving a plurality of zones from each pump module reduces how many pump modules are required. Zones served by one pump module may be selected to have similar thermal loads. Pump modules may supply hot water when heat is needed instead of cooling.

The invention is an apparatus for heating or cooling a room of a building. The apparatus includes a radiant panel supported on a wall, which radiates energy to or from a room. The radiant panel has a conduit for passage of a fluid. The invention also includes a heat exchange device which heats or cools the fluid, which is installed inside the wall between two studs. A first line and second line connect the inlet and outlet to the heat exchange device. A pump that pumps the fluid that is heated or cooled by the heat exchange, whereby the room is heated or cooled depending on whether the fluid is heated or cooled by the heat exchange device.

A cooling system includes one or more cooling panels for affecting a cooling load in an environment. The cooling system also includes a heat exchanger coupled to the one or more cooling panels. Each cooling panel includes a film, a panel body, an inlet port, an outlet port, and a fluid path. The film's radiative properties allow it to achieve a temperature less than an environment temperature. The heat exchanger includes ports that are coupled to the fluid paths of the one or more cooling panels. A control system is used to control flow rates, flow paths, fluid temperatures, component temperatures, cooling rates, component operation, or other aspects of a cooling system. For example, the control system controls or monitors pumps, compressors, fans, valves, sensors, actuators, or a combination thereof.
