In order to solve the cooling in summer problem, the cooling of employing top board mode is arranged, promptly indoor ceiling material changes metallic plate into, feed refrigerant in the pipe laying of face contact type on the metallic plate, pipeline, the metallic plate temperature is reduced, to indoor formation cold emission, thereby reach the purpose of cooling.But adopt this kind method, top board is dewfall very easily, must control the dew-point temperature that the interior refrigerant temperature of pipeline is higher than room air all the time.And the dew-point temperature of room air is relevant with indoor temperature and relative humidity, and with outside air temperature, solar irradiance, the variation of indoor hot humidity load etc. and changing, therefore, refrigerant temperature in the requirement cooling top board must adapt to the variation of room air dew-point temperature at any time, and in the central air conditioner system, the temperature of refrigerant is relatively-stationary, and must satisfy the needs of new blower fan group and other air processor, generally requiring refrigerant temperature is about 7 ℃, and the refrigerant temperature in the cooling top board must be greater than 15-20 ℃, otherwise will condensation, and two kinds of refrigerant temperatures can not be compatible, therefore, in the same central air-conditioning refrigerant engineering, must be provided with two and overlap independently refrigerant system, cause system complex, investment is high, and the machine room floor space is big.
In above-mentioned two kinds of schemes, the former only is used for winter heating, and the latter only is used for cooling in summer, can not summer in winter dual-purpose.
It is shared that the purpose of this utility model provides a kind of summer in winter, low noise or muting conditioner.
To achieve these goals, the technical solution of the utility model is the cold and hot radiation appliance in a kind of floor, it by air conditioner cold and hot water unit, cold and hot matchmaker's circulating pump, new blower fan group, cold heat medium pipe, comb form, output at the air conditioner cold and hot water unit is in series with new blower fan group, cold and hot matchmaker enters the ground comb again by new blower fan group earlier, and then gets back to the air conditioner cold and hot water unit.The ground comb is imbedded in the ground panel construction structure layer, and the surface is provided with safeguard structure, and the outer surface of ground comb also is provided with the expansion heat-transfer surface, and new blower fan group provides new wind by fresh wind tube and electronic volume damper to the space at comb place, ground.
Because earlier through after the new blower fan group, temperature is higher for refrigerant, simultaneously,, surface temperature is risen to more than the dew-point temperature, so this device is when cooling in summer because the safeguard structure layer above the ground comb possesses certain thermal resistance, no condensation phenomenon has been protected building structure.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is conventional central air conditioning plant schematic diagram.
Fig. 2 is the cold and hot radiation appliance schematic diagram in floor.
As shown in Figure 2, the cold and hot radiation appliance in floor by air conditioner cold-heat unit 1, cold and hot matchmaker's circulating pump 2, new blower fan group 4, cold heat medium pipe 5, comb 7 form, output at air conditioner cold and hot water unit 1 is in series with new blower fan group 4, cold and hot matchmaker enters ground comb 7 again after the new blower fan group 4 of cold and hot matchmaker's circulating pump 2 inputs, and then gets back to air conditioner cold and hot water unit 1.Ground comb 7 is imbedded in the ground panel construction structure of air-conditioned room 8, and its surface is provided with certain thickness concrete cover, and the outer surface of ground comb 7 also is provided with the expansion heat-transfer surface, is used for improving the heat exchange effect.New blower fan group 4 provides new wind by fresh wind tube 3 and electronic volume damper 6 to air-conditioned room 8.
In summer, the refrigerant that the air-conditioning unit provides is delivered to new blower fan group through circulating pump, and behind new air heat-exchange, air themperature reduces, and refrigerant temperature raises, and the refrigerant after the intensification is sent into the ground comb again, by after floor and the room air heat exchange, is back to the air-conditioning unit in the ground comb.
In winter, the heating agent that the air-conditioning unit provides is delivered to new blower fan group through circulating pump, through with new air heat-exchange after, air themperature raises, heat medium temperature reduces, the heating agent after the heat exchange is sent into the ground comb again, by after floor and the air heat exchange, is back to the air-conditioning unit in the ground comb.
In order to make ground comb and floor panel structure carry out the heat transmission better, ground comb arranged outside has the expansion heat-transfer surface.In tier building,, make indoor ground and end face all can carry out cold (heat) radiation, thereby form indoor than the even temperature field because each layer is equipped with the ground comb.
The expansion heat-transfer surface of ground comb can be independently to add annex, can be one with the pipeline mother metal also.The ground comb can be a metal tube, also can be nonmetal or metal and nonmetallic multiple tube.
Characteristics of the present invention:
1, in the cover system, can be used for simultaneously winter heating and summer cooling, overcome in the conventional system, The ground comb can only heating, the Bilateral investment that the cooling top board can only cooling, the disadvantage of unidirectional use.
2, summer, because the air conditioner coolant employing is series system, namely refrigerant changes by new blower fan group earlier After heat heats up, enter again ground comb circulation, make the refrigerant temperature that enters the ground comb higher, simultaneously, Certain thickness concrete cover above the ground comb, comparatively favourable to even diffusion and the temperature damping of heat, The more important thing is, in the structure of ground comb, underground pipe is provided with expansion heat-transfer surface structure, more have Be beneficial to the even diffusion of heat. After adopting this programme, import the temperature of floor surface into greater than indoor Dew-point temperature, overcome the easy condensation of conventional underground pipe and the cooling top board must be stricter control cold The disadvantage of matchmaker's temperature makes central air conditioner system needn't arrange two and overlaps or overlap more coolant system.
