Description
Technical field
The present invention relates to energy-conserving construction wall field, be specifically related to a kind of body of wall based on heat pipe and heating system.
Background technology
Low-energy building will become the development trend of building from now on, and China's building energy consumption accounts for about three one-tenth of total energy consumption, and wherein more than 1/3rd for the heating of building and refrigeration.Low-energy building refers to or need not use primary energy as far as possible less, and uses regenerative resource to carry out heating and refrigeration to building.
Intelligence body of wall, namely by the construction wall that exterior temperature change regulates interior temperature, is the basis of low-energy building.Application number is that 201110381071.7 (publication number is CN102493574A) disclose a kind of solar energy warm wall construction, main wall external body is fixed with heat sink from the inside to the outside successively, outer surface has heat-sink shell warming plate, plane skylight.Being the heating of whole body of wall by solar energy, simultaneously at outer setting venetian blind type sunbreaker, can sunlight being stoped when not needing to inject on plane skylight.But total is without high-efficiency heat conduction layer, solar heat is made to be difficult to be transmitted to indoor fast.
Authorization Notice No. is that the Chinese utility model patent of CN203008146U discloses a kind of external wall pre-buried type hot tube energy saving device, comprising: contacting successively according to the cycle fluid flow direction arranges and form the heat exchange unit of closed circuit, the power unit driving cycle fluid to flow and the underground pipe arranging underground; Working medium compensating unit and voltage regulation unit is also provided with in described closed circuit; Described heat exchange unit is embedded in external wall, and comprise the summer fever pipe heat exchanger that is arranged in parallel and winter heat-pipe heat exchanger and selective open summer fever pipe heat exchanger and winter one of heat-pipe heat exchanger control unit.This device can reduce temperature between external wall rendering layer and masonry basic unit summer, reduces exterior wall external surface and conducts to the heat of exterior wall inner surface, reduce Summer Indoor refrigeration duty; Winter can improve temperature between external wall rendering layer and masonry basic unit, effectively reduces exterior wall inner surface and conducts to the heat of exterior wall external surface, reduce indoor heat load in winter, reduce indoor heating energy consumption.This device needs to bury underground pipeline underground, and utilize underground heat to change body of wall problem, underground pipe easily corrodes, and cost is also relatively high.
Authorization Notice No. is the complete sets of equipment that the Chinese utility model patent of CN203099983U discloses a kind of solar source wall and heat pump and combines, comprise thermal source wall and heat pump, wherein thermal source wall is spliced by polylith solar absorber plate, this thermal source wall also comprises the heat exchanger tube being with heat pipe import and heat pipe to export, absorber plate inside is provided with the square opening or circular port that pass for heat exchanger tube, and absorber plate outer wall is provided with solar energy absorbing coating; Heat pipe outlet is connected with the inlet of heat pump and liquid in heat exchanger tube and heat pump are connected into heat pipe import from the liquid outlet of heat pump after carrying out interchange of heat again.This device can utilize thermal source wall absorption sunshine and convert heat energy to, then is people's heating and manufacture hot water by heat pump.
