Abstract
The utility model relates to an end device for a variable air volume air-conditioning system, which belongs to a device which regulates air flow volume of a room to maintain room temperature in order to compensate indoor load variation in the variable air volume air-conditioning system. The utility model is characterized in that a variable frequency blower is used for taking the place of an air volume measuring device and an electric air valve which are in an original throttle-type end device, and the air flow volume of the room is controlled by regulating the rotation speed of the blower. As the utility model adopts the variable frequency blower, the throttle energy loss caused by the air valve is eliminated, and the air volume measuring device is also omitted, and accordingly, the cost can be reduced to a great extent; on the other hand, each end user can start and shut down an end blower at any time according to needs; the use is convenient and flexible, and the system stability can be effectively improved.
Description
The utility model relates to the end-equipment that uses in a kind of air conditioning system with variable.
End-equipment is for the change of compensated chamber's internal loading, regulates the room air output to keep the equipment of room temperature, also is the key equipment in the variable air volume system.At present, what generally adopt in the prior art is a kind of throttle-type terminal device, and it is to regulate the air output in room to reach the purpose of keeping room temperature by the resistance that changes throttling arrangement.This throttle-type terminal device is mainly by casing, volume adjusting apparatus, and control appliance three parts are formed, and its volume adjusting apparatus comprises surveys air quantity device and Electric air valve, referring to " air conditioning design manual ".Its shortcoming of this kind end-equipment have following some: the one, the minimizing of air quantity is to realize that by the throttling energy loss that increases throttling arrangement therefore, air quantity is more little, energy loss is big more.The 2nd, a device of surveying air quantity is all arranged on each end-equipment, according to the size of survey air quantity, by regulating Electric air valve to reach needed air quantity, this makes structure become complicated undoubtedly, thereby has improved construction costs.The 3rd, when certain room air quantity changes, bigger to the stabilizing influence of adjacent rooms air quantity.
At the deficiency and the defective of above-mentioned existence, the purpose of this utility model provides a kind of end equipment of new air conditioning system with variable, and this device not only can reduce the energy consumption of system, reduces cost; Can improve simultaneously the stability of system effectively.
The utility model is achieved through the following technical solutions, and it is mainly by the casing that is connected with main air duct, control appliance, and volume adjusting apparatus three parts that are contained in the casing form, and it is characterized in that volume adjusting apparatus adopts frequency conversion fan.
In order to prevent that after turning off the blower fan in certain room, the air in this room can not blow back into main air duct, a check-valves is housed in the blower fan back.
The drawing explanation:
Accompanying drawing 1 is the structure diagram of the throttle-type end-equipment that uses in the prior art.
Accompanying drawing 2 is a structural representation of the present utility model.
Below in conjunction with description of drawings concrete structure of the present utility model and embodiment:
The throttle-type end-equipment of Fig. 1 for using in the prior art, the 1st, main air duct, the 2nd, the casing of end equipment, 3 and 4 are respectively apparatus for measuring air quantity and Electric air valve, and the 5th, be contained in the blinds valve air port in exit.Fig. 2 is a structural representation of the present utility model, and frequency conversion fan 6 is housed in casing, to replace original apparatus for measuring air quantity 3 and Electric air valve 4.Between blower fan and blinds valve air port, check-valves 7 is housed also, its objective is after blower fan is turned off, prevent that air from being blowed back in the main air duct by the room.The size of each room air output can realize that the rotating speed of blower fan then is to be determined by control appliance by the factor that PID adds the running status of considering other blower fan by room temperature by adjusting rotation speed of fan.
The utility model compared with prior art has the following advantages and beneficial effect.
Owing to adopted frequency conversion fan to replace original apparatus for measuring air quantity and Electric air valve, both eliminated The throttling energy loss that air-valve causes has been saved again apparatus for measuring air quantity, but thereby the decrease engineering make Valency. On the other hand, each terminal temperature difference can be at any time opening and closing tail-end blower fan separately as required, not only Easy to use, flexible, and littler to the impact of the load in other room, thus system effectively improved Stability.
Claims (2)
1, a kind of end equipment of air conditioning system with variable, mainly by the casing [2] that links to each other with main air duct [1], the volume adjusting apparatus and the control appliance that are contained in the casing are formed, and it is characterized in that above-mentioned volume adjusting apparatus adopts frequency conversion fan [6].
2,, it is characterized in that check-valves [7] being housed in the back of frequency conversion fan [6] according to the end equipment of the described air conditioning system with variable of claim 1.
