Disclosed is a building envelope, in particular a building wall, floor, or roof, comprising at least two spaced-apart shells that enclose an intermediate space therebetween, said intermediate space being essentially empty except for weight-bearing and/or construction engineering elements or being filled in at least some sections with porous, open-cell material and being sealed from the exterior and interior of the building. Controllable sealing means are provided for sealing the intermediate space against the exterior and interior and sealing optionally separated building envelope sections against each other.

In an air-conditioning hot-water supply combined system 100, in a state where at least one of one or more indoor units 130 and at least one of one or more hot-water supply units 140 are running, when at least another one of the indoor units 130 and the hot-water supply units 140 submits an operation permission request and it is determined that, if the at least another one of the indoor units 130 and the hot-water supply units 140 having submitted the operation permission request additionally runs, the capacity of a heat source unit 110 is exceeded, suspension of the at least one running indoor unit 130 fulfilling a predetermined condition is performed repeatedly until the allowable operation capacity of the heat source unit 110 becomes satisfied, and the performance of the heat source unit is allocated to the hot-water supply unit 140 having submitted the request.
摘要:
The present invention relates to a modular panel for thermal energy transfer particularly configured for being used in ceilings and walls, comprising a heat-insulating layer (2) forming a supporting structure demarcated by a lower face (2A), an upper face (2B), two side faces (2C, 2D) and two end faces (2E, 2F). Said panel (1) comprises at least one conducting plate (3) attached to the lower face (2A). Said conducting plate (3) is formed by a groove (31) embedded in the heat-insulating layer (2), defining a longitudinal cavity (32) which is configured to house a hydraulic pipe (6), and defining a longitudinal opening (34) which allows inserting the hydraulic pipe (6); a transfer plate (35) extending on the lower face (2A) and closure means (4) configured to seal the longitudinal opening (34) and press the hydraulic pipe (6) against the groove (31).

摘要:
A heat pump system, including a main heat pump system and a directly expanded strong cool-heat radiation plate provided on the building surface and serving as the terminal of the main heat pump system. The directly expanded strong cool-heat radiation plate enables refrigerant in the main heat pump system to circulate therein. Since the heat pump system of the present application adopts the directly expanded strong cool-heat radiation plate as the terminal of the main heat pump system, refrigerant in the main heat pump system may exchange heat with air by means of the directly expanded strong cool-heat radiation plate directly, instead of secondary heat exchange of the refrigerant loop and the water circulation loop, thereby reducing loss in intermediate heat exchange, improving the heat exchange efficiency and heat utilization, and omitting the circulating pump for water circulation. An air-conditioner with the heat pump system is further disclosed.
摘要:
This air conditioner appropriately controls the temperature of a radiant panel (radiant heat exchanger). The air conditioner has a compressor (60), an outdoor motor-operated valve (64), an outdoor heat exchanger (62), an indoor heat exchanger (20), and a radiant panel (30), and is provided with a refrigerant circuit (10) that is configured in a manner so that high-temperature refrigerant flows to the radiant panel (30) during a radiant heating operation. During the radiant heating operation, a panel incoming temperature sensor (25) is provided to the conduit upstream from the radiant conduit of the radiant panel (30), and a panel outgoing temperature sensor (26) is provided to the conduit downstream from the radiant conduit of the radiant panel (30). An indoor motor-operated valve control unit controls an indoor motor-operated valve (23) provided upstream from the radiant conduit of the radiant panel (30) on the basis of the temperatures detected by the panel incoming temperature sensor (25) and the panel outgoing temperature sensor (26).
摘要:
A precast monolithic concrete prefabricated, composite building construction module formed of a substantially planar rear wall. The rear wall has embedded therewithin a radiator pipe for circulating a fluid at a temperature that is different from an ambient temperature of the modular component within the rear wall. The module may comprise at least one side wall integral with the rear wall that terminates at one end at a corresponding end of the rear wall. The rear wall has a length and each of the at least one side walls has a length and extending in a first direction substantially normally away from the rear wall sufficient to substantially enclose and define walls of a standard facility, the at least one side wall supporting the rear wall to cause the module to be free-standing while devoid of lateral support. The radiator pipes are interconnected through inlet/outlet junctions by tubing with other inlet/outlet junctions to permit a single circulating fluid source to circulate fluid through the radiator pipes of a plurality of the modules making up a building structure.
摘要:
In order for a temperature-control system for buildings, comprising a circuit for a liquid heat-transfer medium, in which at least one internally interactive heat-exchanger unit and one externally interactive heat-exchanger unit are provided, to be improved such that it can be used for the temperature control of a building, as far as possible, even in hot weather, it is proposed that the temperature-control system can be operated in a cooling-operation mode, in which it dissipates heat to the outside, and that the externally interactive heat-exchanger unit has a radiating surface which can dissipate heat by heat radiation in the cooling-operation mode.
