Had the advantages that using capillary network or radiant panel it is very much, such as:
High degree of comfort.Through practice have shown that, radiation is the highest heat transfer type of comfort.And capillary network or radiant panel air-conditioning The cooling capacity and heat of end system 60% are carried out by way of radiation, thus comfortable compared with the Terminal device of other forms It spends relatively high.
Since radiant panel or capillary network are using parallelpiped or the serial pipe composition of spacing very little, it is uniformly distributed, heat Radiation exchange area is especially big, so room temperature is highly uniform.Hot/cold radiating surface is substantially without temperature difference.And people The heat exchange in body and space is mainly that the form radiated carries out, this static state refrigeration and naturally warm environment make one body-sensing to non- Chang Shushi, the temperature that body is felt are 2~3 DEG C higher than room temperature.This point can additionally achieve the purpose for saving the energy.Each room Between use alone cycle structure, therefore the climator by being mounted on room can be controlled separately each room temperature.
Terminal device the most quiet.(there are the indoor fortune such as motor, blower for fan coil compared with traditional fan coil Therefore dynamic component can generate the noise of 35~45dB or so), indoor radiation tail end 14 does not have indoor sport component, will not generate Any room noise is air-conditioning system the most quiet.
Interior is without condensing water pond, bacteria breed source being not present.Indoor radiation tail end 14 be embedded in furred ceiling or within the walls or It is hung directly from ceiling, it is indoor compared with fan coil not condense mainly by radiant heat transfer to building cooling supply or heat supply Water system will not occur impeded drainage, cause phenomena such as dripping.Also thin there is no being bred in traditional fan coil drain pan Bacterium, the phenomenon that influencing indoor sanitation condition.
Energy-saving effect is significant.The summer supply water temperature of usually interior radiation tail end 14 is 7-20 degree, the supply water temperature in winter For 25-40 degree, there are higher summer supply water temperature and relatively low winter supply water temperature relative to traditional air conditioner, can save a large amount of The energy.
Stronger cold-storage/heat storage capacity.Temperature will not all rise within the long period under the states such as system closing or power failure High (summer) or reduce (winter).
Stronger self-adjusting balance ability.Summer increases with the raising of room temperature and the radiating surface temperature difference, improves spoke Penetrate cooling capacity.Winter increases with the reduction of room temperature and the radiating surface temperature difference, improves radiations heat energy.
The indoor occupancy of radiation tail end 14 building headroom is small, saves space.Capillary network tail-end is such as used, in air-conditioned room It is interior it is levelling after furred ceiling under or metope on be first laid with capillary network, then spread the plaster of 5-10mm thickness, forming radiating surface is It can.If using radiant panel, it is only necessary to hang on ceiling radiant panel as ceiling board, be quickly and expediently installed, beautiful outline form It sees generous.It is particularly suitable for being used cooperatively with heat pump class Cooling and Heat Source, achievees the effect that more energy efficient.
From the above, it is seen that include multiple outdoor machine parts, multiple indoor unit parts, multiple indoor radiation tail ends 14 and Whole control system.Wherein each outdoor machine part include compressor 12, oil return apparatus, high-voltage switch gear 13, low tension switch 11, 7, four four-way reversing valve 6, third ratio triple valve electric two-way valves, third surface air cooler 4, electric expansion valve, thirds are dried Filter 8, axial flow blower 5;Each indoor unit include fluorine water- to-water heat exchanger 18, the second device for drying and filtering 19, the first electric expansion valve 29, First ratio triple valve 32, centrifugal blower 34, surface air cooler, the second electric expansion valve 20, the second ratio triple valve 22, power cycle Water pump 17 etc., indoor radiation tail end 14 include the various radiant type ends such as capillary network, metal radiant panel, gypsum radiant panel, cold beam End and its pipe-line system.Control system includes central control board 1, outdoor unit control panel 3, indoor unit control panel, temperature sensor 30, water temperature sensor 15, data line 2 etc..
When cooling in summer removes wet cooling condition, as shown in Fig. 2, the gaseous freon of low-temp low-pressure passes through the compression of compressor 12 Afterwards, the gaseous state for becoming high temperature and pressure divides by third ratio triple valve 7 for two-way, all the way by the first electric two-way valve 26 into In the part for entering each indoor unit processing air, then by the first ratio triple valve 32 progress assignment of traffic, according to each indoor unit Actual demand distribution inputs the flow of each indoor unit air treatment section.The gaseous state freon of high temperature and pressure enters the first table therewith Cooler 31 carries out heat temperature raising to by the air after cooling of the second surface air cooler 33, and high temperature and pressure freon becomes medium temperature and medium pressure Liquid, then become the gas-liquid mixed state of low-temp low-pressure after the throttling of the first electric expansion valve 29, it is cold to subsequently enter the second table The freon of device 33, low-temp low-pressure absorbs heat in the second surface air cooler 33, becomes the gaseous state of low-temp low-pressure, after by third electronic two Port valve 24 is compressed into compressor 12, reciprocation cycle.
Divide the another way freon for two-way by third ratio triple valve 7, it is cold to enter third table by four-way reversing valve 6 Device 4, in third surface air cooler 4, axial flow blower 5 is operated, and accelerates the heat exchange of outdoor air and third surface air cooler 4, and third table is cold The freon of high temperature and pressure in device 4 becomes the liquid freon of medium temperature and medium pressure, and then the liquid freon of medium temperature and medium pressure passes through After third device for drying and filtering 8, third electric expansion valve 9, third device for drying and filtering 8, become the gas-liquid mixed state of low-temp low-pressure, with Freon passes through ratio triple valve afterwards, distributes to the second electric expansion valve 20 in each indoor unit circulating part point, by throttling It exchanges heat afterwards into fluorine water- to-water heat exchanger 18 in each indoor unit circulating part point.Subsequently become the gaseous state freon of low-temp low-pressure Afterwards, it is compressed by four-way reversing valve 6 into 12 suction end of compressor, reciprocation cycle.
The effect that so circulation is formed is: by the circulation of freon, so that being made in each indoor unit circulating part point The high temperature cold water that summer cold emission needs, while being made in each indoor unit air treatment section by circulation, enter room to from outdoor Interior air forms the dehumidifying of first depth, then etc. wet heating process, not only humidity was handled well, but to dehumidifying after Cold air heated up, make be sent into drying-air temperature be suitable for.In the radiation tail end of connection, by fluorine water- to-water heat exchanger 18, By the circulation inflow temperature control in radiation tail end in 16-18 degrees centigrade, recirculated water enters by power cycle water pump 17 Circulation is formed in radiation tail end, to indoor radiation cooling.Return water is adjusted by the second ratio triple valve 22, passes through water temperature sensor The leaving water temperature situation of 15 perception, so that the ratio of unlatching is adjusted, control and the quantity of circulating water in water inlet connection branch, Jin Erjin One step accurately control system leaving water temperature.
Circulation when winter heating is as shown in figure 3, just the opposite with circulation when cooling in summer.
The circulatory system principle of system is as shown in Figure 3.By the circulation of freon, the effect that can achieve are as follows: indoor unit Air treatment section carries out depth dehumidifying to the air that outdoor enters the room, while carrying out reheating, makes after being sent into indoor dehumidifying Air themperature be suitable for that indoor unit circulating part point produces indoor radiation tail end 14 by freon and radiates required low temperature Hot water, low-temperature water heating pass through efficient indoor radiation tail end 14 to indoor radiating again, form heating effect.So on circulate, By same set of system, efficiently solving yellow plum season needs also to have refrigerated dehumidification while heating the application of demand to ask Topic.Simultaneously because system can introduce fresh air, additionally it is possible to guarantee the freshness of indoor air.
