摘要:
An air purification device with ozone and fine dust cleaning, and optionally with a heating function, cooling function and dehumidifying function, is configured for installation in a space in a building. The air purification device comprises a first air duct (6) for feeding in fresh air, and a second air duct (7) for carrying away extracted air. The two air ducts (6, 7) lead through a heat exchanger (12). The air purification device also comprises a third air duct (8) which opens into the first air duct (6) downstream of the heat exchanger (12). An electric filter/ozone generator (9, 10) is arranged downstream of the inlet (1) in the first air duct (6) and downstream of the inlet (3) in the third air duct (8). An activated carbon filter (11) is arranged upstream of the output of the first air duct (6). In the first air duct (6), a first blower (13) is arranged downstream of the electric filter/ozone generator (9) and a second blower (14) is arranged upstream of the activated carbon filter (11). A control unit (17) is programmed to operate the second blower (14) with a larger suction power than the first blower (13) in at least a first operating mode.

A room air conditioner with a liquid-to-air heat exchanging device for the exchange of heat between a liquid and air has a first flow channel (2; 2A) for the air and a second flow channel (5) for the liquid, and at least one Peltier element (14). The heat exchanging device (1) is subdivided into a first stage (17) in which a heat exchange occurs in a passive manner between the liquid and air, and a subsequent second stage (18) in which heat is pumped from the liquid to the air or from the air to the liquid by supplying an electrical current to the at least one Peltier element (14).

A device for drying an air stream comprises at least one first module (7) comprising at least one Peltier element (13) and at least one second module (8) comprising at least one Peltier element (13). The entirety of the first module (7) forms a first zone (4) for cooling the air stream. The entirety of the second module (8) forms a second zone (5) for drying the air stream. The entirety of the first and the second modules (7, 8) forms an air channel for the air stream. A water discharge channel (9) is disposed below the entirety of the second module (8) and receives water incident during the drying of the air stream in the second zone (5). At least one sensor (30) for measuring a temperature and/or a moisture of the air stream provides at least one output signal. A control unit comprising at least one controller controls the Peltier element (13) based on the at least one output signal of the at least one sensor (30).
摘要:
The invention relates to a method for operating a liquid-to-air heat exchanging device, in which heat is exchanged between the liquid and the air at least in a first passive heat exchanging stage (2), comprising the following steps: determining the dew point temperature of the ambient air, determining if the dew point temperature of the ambient air is higher than the temperature of the liquid, and if this is the case, operating the heat exchanging device in an operating mode described as pulse operation according to the following steps: allowing the liquid to flow through the first heat exchanging stage (2) during a predetermined time period, preventing the liquid from flowing through the first stage, and measuring and monitoring the temperature of the air after the air has exited the first heat exchanging stage (2), wherein the temperature of the air measured after the air has exited the first heat exchanging stage (2) indicates a first temperature rise, then remains at an approximately constant level for a certain time, and then indicates a second temperature rise, detecting the second temperature rise, and ending the prevention of the liquid from flowing through the first heat exchanging stage (2) after the second temperature rise has been detected, and repeating said steps until the dew point temperature of the air is higher than the temperature of the liquid.

The invention relates to an arrangement for air conditioning rooms. The arrangement comprises a central heating device (1), to which several lines (2a, 2b, 3a, 3b, 4a, 4b) containing a heat-transferring fluid are connected. The arrangement further comprises a plurality of decentralized, electrically operated heat pump units (5, 6, 7, 8), which are connected to the central heating device (1) by means of said lines (2a, 2b, 3a, 3b, 4a, 4b) so as to enable energy transfer. The particular heat pump unit (5) comprises a plurality of heat pump modules, which absorb thermal energy from the fluid in order to heat and which deliver thermal energy to the fluid in order to cool and/or dehumidify. Said heat pump modules preferably comprise Peltier elements acting as heat pump elements.

The invention relates to a plate heat exchanger for exchanging heat between a first air stream (11, 12) and a second air stream (13, 14) comprising a plurality of plates (1) limiting exchange chambers which are serially arranged in a transversal direction with respect to said plates (1). The first air stream passes through one part of the exchange chambers (11, 12), the second air stream passes through the other exchange chambers (13, 14), preferably in an opposite direction. The second air stream consists of the air (13) removed from ventilated premises. A water distribution system (20, 21) is used for supplying water to the exchange chambers of the second air stream (13, 14) in such a way that the removed air is cooled by contact and evaporation, thereby lowering the external air temperature.

The air to be supplied to a room is brought to a desired temperature and a desired humidity through the following processing steps: - flowing outside air as a first air stream through a first line (20) and flowing a first portion of exhaust air coming from the room as a second air stream through a second line (21), wherein moisture is exchanged between the first air stream and the second air stream by way of a device for exchanging moisture, condensing, by way of a drying and cooling device (19), moisture in the form of water from the first air stream and/or from the second air stream and/or within the device for exchanging moisture, and flowing a second portion of the exhaust air as a third air stream through another line (32) comprising another drying and cooling device (33) and returning said second portion back to the room, wherein moisture is condensed from the third air stream in the form of water in the other drying and cooling device (33).
