Description
Technical field
The present invention relates to a kind of heat-exchange apparatus for heating ventilation air-conditioning system, in particular for the adjusting device of the radiator of water circulation heat exchange.
Background technology
The heating ventilation air-conditioning system of existing employing radiator, mostly is water circulation heating system, also can be used for water circulation refrigeration system.The kind of radiator is a lot, generally can be divided into by material and manufacture craft: cast-iron radiator, steel radiator, composite copper aluminium radiator, die casting aluminium composite heating radiator, steel combined with aluminum radiator etc.
Radiator, as the end-equipment of heating ventilation air-conditioning system, has great impact to the operational efficiency of whole system.Because radiator itself has intrinsic performance curve, in relatively-stationary environment, heat transfer coefficient is basicly stable.
For heating system, from the angle of " behavior energy saving ", when indoor, while having heating demand, the heat transfer coefficient of radiator is high, heat dissipation capacity greatly more can meet application demand; But while not having heating demand, radiator to maintain antifreeze function, the heat transfer coefficient of radiator is low, heat dissipation capacity is little more energy-conservation when indoor.There is obvious contradiction in both of these case, and this contradiction is difficult to solve in existing system.
For central heating system, the relatively good control of supply water temperature, but the more difficult control of the return water temperature of each end.If can effectively control return water temperature well, the operational efficiency of system and stability all can strengthen.
Summary of the invention
The object of the invention is the heat dissipating housing 2 by increase force air circulation regulatory function on radiator 1, thereby strengthen the controllability of radiator 1 self, make the means of overall system regulation and control more flexible.
Object of the present invention realizes by following measures: wrap radiator 1 with heat dissipating housing 2, heat dissipating housing 2 is provided with air inlet 4 and air outlet 5, one or more blower fans 3 for realizing force air circulation are installed between heat dissipating housing 2 and radiator 1, wherein comprise control circuit 6 and power supply, control circuit 6 can be controlled the operation of blower fan 3, air inlet 4 and air outlet 5; In the time that blower fan 3 is worked, air enters behind radiator 1 surface and is sent by air outlet 5 from air inlet 4, circulated and promoted exchange heat by force air, control circuit 6 can pass through to change the rotational speed regulation amount of air circulation of blower fan 3, thereby changes the heat transfer coefficient of radiator.
Beneficial effect of the present invention is:
1,, after installing heat dissipating housing 2 additional on radiator 1, when system is during in Heating State, heat dissipating housing 2 surface temperatures are lower than radiator 1, so not only can scald preventing, and lay the first stone for the supply water temperature of further raising system;
The heat-exchange capacity upper limit of the radiator 12, making by forced circulation improves, and can support the larger backwater temperature difference, more energy-conservation that enters; The highest supply water temperature that this radiator is suitable for can be more than or equal to 90 DEG C, and minimum return water temperature can be less than or equal to 40 DEG C, can realize T >=50K into backwater temperature difference △;
3, by regulating the power of forced circulation, can change easily the inherent characteristic of radiator, thereby promote the performance-adjustable of whole system;
4,, after installing heat dissipating housing 2 additional on radiator 1, it is ornamental better; Not only can play occlusion effect, more can keep unified by the design style and the interior decoration style that change heat dissipating housing 2.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
Embodiment 1:
Concrete structure of the present invention is as shown in accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, and direction, the position of air inlet 4 and air outlet 5 can be adjusted.Carry out force air circulation time, wind direction, wind speed can regulate by control circuit 6.Air inlet 4 and air outlet 5 places can arrange removable filter net 8, for filtering dust, foreign matter.The structure of air inlet 4 and air outlet 5 and control method can be with reference to the structure of domestic air conditioning and control methods.
Air outlet 5 can be arranged at the lower end of heat dissipating housing 2, the position of ground proximity, preferentially promotes the temperature of room lower layer space, to reach more comfortable effect.
When hour (as being highly less than 1000 millimeters) of size of radiator 1, heat dissipating housing 2 can wrap radiator 1 completely; In the time that the size of radiator 1 is larger (as being highly greater than 1500 millimeters), now the mode of parcel is just more difficult completely, and heat dissipating housing 2 can take part to wrap the form of radiator 1.
When indoor nobody time, radiator takes low demand to maintain operating mode, prevents that pipeline from freezing is main, now control circuit 6 can stop the running of blower fan 3, and close air inlet 4 and air outlet 5, radiator is closed, the heat exchange amount of radiator is dropped to minimum, be more conducive to insulation.
Embodiment 2:
Now, the most frequently used system regulating measure is to change the flow of radiator to regulate heat exchange amount, often causes return water temperature also to change but change when flow, and this just causes the decline of system control accuracy.
For addressing this problem, can be provided with the temperature sensor 7 of measuring water temperature at the water inlet of radiator and water return outlet place, temperature sensor 7 is connected with control circuit 6, and control circuit 6 can regulate in real time according to the real time data of temperature sensor 7, change targetedly the power of force air circulation and then maintain the stable of return water temperature.Concrete grammar is as follows:
1, first, established standards return water temperature, radiator are started working;
2, control circuit 6 is by temperature sensor 7 Real-Time Monitoring return water temperatures;
3,, for heating system, when return water temperature is during higher than standard value, control circuit 6 heightens the rotating speed of blower fan 3 gradually until return water temperature is up to standard; For refrigeration system, when return water temperature is during lower than standard value, control circuit 6 heightens the rotating speed of blower fan 3 gradually until return water temperature is up to standard; When air quantity is brought up to maximum and return water temperature is still not up to standard, system alarm;
4,, for heating system, when return water temperature is during lower than standard value, control circuit 6 turns down the rotating speed of blower fan 3 gradually until return water temperature is up to standard; For refrigeration system, when return water temperature is during higher than standard value, control circuit 6 turns down the rotating speed of blower fan 3 gradually until return water temperature is up to standard; When air quantity is reduced to minimum and return water temperature is still not up to standard, system alarm.
When actual temperature of return water and standard return water temperature difference be less than ± 1 degree Celsius time, can think that normal phenomenon, system can not regulate.
By above apparatus and method, can in wider range of flow, maintain the stable of return water temperature, in the time that carrying out Flow-rate adjustment, system just there will not be like this situation of return water temperature fluctuation, and make the accuracy of Flow-rate adjustment higher.
Above embodiment is not to concrete restriction of the present invention, in the scope that does not depart from claims restriction of the present invention, can make all concrete amendments to this device.
