Abstract: A dynamic air supply system for controlling ventilation in a clean room, wherein the clean room comprises a clean area subject to contamination, comprising a radiant panel arranged within a ceiling above the clean area, a first air supply diffuser and a second air supply diffuser arranged within the ceiling, a controller coupled with the air supply diffusers for controlling the air supply. The first air supply diffuser and the second air supply diffuser are arranged on opposite sides of the radiant panel. The first air supply diffuser and the second air supply diffuser are arranged to diffuse air flows along the radiant panel and towards clean area. The controller is configured to change the air supply diffusers between nursing mode and normal mode, wherein the supply air volume in normal mode is 10%-65% of the supply air volume in nursing mode.

Abstract: An air terminal device with integral light fixture for a clean room, comprising a housing having a cover panel comprising at least one opening, a light fixture for providing light outside of the air terminal device, an air chamber configured to receive air and to discharge air out of the air chamber, wherein the air is configured to be transferred through the at least one opening in the cover panel, wherein the light fixture is arranged inside the air chamber, and the cover panel comprises at least one light fixture opening, in which the light fixture is integrated.

Abstract: An apparatus for conditioning a space includes a frame; an internal space within the frame, into which internal space a supply air flow is conducted; a cover panel into which a perforated area is arranged, the perforated area including perforations, each perforation having a diameter; and a heat exchanger arranged within the frame and including at least one heat exchanger coil, lamellas, and openings arranged between each adjacent lamella, each opening having a length.

Abstract: A controlled dilution fluid flow pattern is described. In an embodiment, a fluid supply device is configured for controlling a pattern of a flow of a fluid within a critical room. The critical room comprises a critical area subject to contamination. A first fluid supply nozzle is configured to provide a first fluid supply jet to provide a first flow of the fluid towards a substantial center of the critical area. A second fluid nozzle is configured to provide a second fluid supply jet to provide a second flow of the fluid towards a perimeter of the room. A momentum of the first fluid supply jet and a momentum of the second fluid supply jet are adjusted so that the substantial center of the critical area is flushed by the first flow and penetration of the second flow into the substantial center of the critical area is generally prevented. In other embodiments, a HVAC system and method are discussed along with the features of the device.

Abstract: According to examples a system, a method and a computer program for controlling at least one indoor environmental condition of a room, comprising: At least one processor, and at least one memory storing program instructions that, when executed by the at least one processor, cause the apparatus to: Receive data of a number of persons within the room. Receive second data of a clothing of the persons. Based on the first and the second data, send a signal to at least one hvac de-vice of the room configured to control a level of a cleanness of the indoor environmental condition.

Abstract: An intelligent electrical power network control and/or protection device comprises at least one power supply connection for connecting the device to a main power source and an auxiliary power source and at least one unit configured to monitor main power, the unit being configured to activate a signal indicating lack of main power in response to lack of main power. The device further comprises at least one unit configured to provide a state control operation for changing an operating state of at least one unit of the device or an operating state of at least one unit to be connected to the device from an operative mode t a power saving mode in response to the activated signal indicating the detected lack of main power.

Abstract: The present invention provides a measured containment control system fitted to a laboratory containment device 1. These devices can have a variety of coherent enclosure configurations in terms of size and geometry. User access to these devices can be by means of either an opening or the use of gloves with, in this latter case, typically filtration of the intake and exhaust ventilation. The system comprises further at least one sensor 6, an exhaust duct 5 or exhaust outlet connected to the laboratory containment device 1 for ventilation, an air flow control means 2 for controlling the exhaust air volume in the exhaust duct 5 and a control unit 13 connected to at least one sensor 6 and to the air flow control means 2. The control unit 13 is arranged to receive signals from at least one sensor 6 constantly and adjusting, based on these signals, the air flow control means 2 to change the exhaust air volume from the laboratory containment device 1.
