Description
Technical field
The present invention relates to the air conditioner ventilation technology, be specifically related to a kind of air-conditioning box, being applicable to variously has accurate control requirement, can set the air-conditioning system of size requirement again resh air requirement.
Background technology
About 30% of China's building energy consumption account total energy consumption, in the building energy consumption, air conditioning energy consumption accounts for significant proportion.For the all-air conditioning system, about 1/3 of novel wind energy consumption duty adjusting system total energy consumption, so the accurate control of resh air requirement size directly concerns the total energy consumption of air-conditioning system.
Transition season, outdoor air parameter satisfy new wind and freely cool off when requiring, and air-conditioning box should have the increasing resh air requirement, adopt the free cooling of new wind to reduce the function of system energy consumption and operating cost; Non-transition season, resh air requirement should satisfy the minimum fresh air requirmente demand, and with the assurance indoor air quality, so the resh air requirement size should can be set according to concrete working condition again.
Existing air-conditioning box does not possess accurately control function of resh air requirement size, the present invention can control the steady state value of resh air requirement size for setting in advance, simultaneously can set the resh air requirement size again according to the operating mode demand, the control resh air requirement is newly-installed steady state value, is guaranteeing that the air quality prerequisite is issued to the air conditioner system energy saving purpose.
Summary of the invention
The purpose of this invention is to provide a kind of air-conditioning box that can set constant resh air requirement again, by at the new air return section of air-conditioning box and outside the differential pressure measurement device being set, regulate the aperture of air returning valve according to magnitude of pressure differential, make the pressure reduction of new air return section and outside remain the steady state value of setting, thereby realize the accurate control to the resh air requirement size, and then reduce the novel wind energy consumption, save operating cost.
For achieving the above object, the technical solution used in the present invention is: a kind of air-conditioning box that can set constant resh air requirement again, be connected from the upstream to arranged downstream successively by new air return section, intermediate effcient fillter section, cold and hot swapdisk pipeline section, humidifier section and air supply section, fresh wind tube and backwind tube are positioned on the described new air return section, new wind dibit Electric air valve is positioned on the described fresh wind tube, and return air motorized adjustment air-valve is positioned on the described backwind tube.Actuator is positioned on the described return air motorized adjustment air-valve, the negative pressure pressure-measuring pipe places the stable place of described new air return section internal pressure, the zero-pressure pressure-measuring pipe places the stable place of pressure outside, described negative pressure pressure-measuring pipe and described zero-pressure pressure-measuring pipe are connected on the differential pressure pickup, described differential pressure pickup links to each other with controller, and described controller output signal is to the described actuator of described return air motorized adjustment air-valve.
In the such scheme, differential pressure pickup and controller can be placed on indoor or outdoors.In view of easy to maintenance, differential pressure pickup and controller are preferably mounted at outdoor.
In the technique scheme, under the fresh wind tube resistance certain condition, new air return section and outdoor air pressure difference and resh air requirement size are one-to-one relationship.According to the required resh air requirement size of system, draw its corresponding pressure difference, make the new air return section of air-conditioning box and outside pressure reduction reach the value of setting by regulating the backwind tube valve area, thereby guarantee that resh air requirement is required steady state value.
Because technique scheme is used, the present invention compared with prior art has following advantage: the present invention is by increasing negative pressure pressure-measuring pipe, outside increase zero-pressure pressure-measuring pipe at new air return section, the force value that negative pressure pressure-measuring pipe and zero-pressure pressure-measuring pipe are recorded is transferred to differential pressure pickup, differential pressure pickup is passed to controller with signal, by the actuator on the controller control return air motorized adjustment air-valve, regulate return air motorized adjustment valve area and make that pressure reduction is the steady state value that arranges, thereby realize the accurate control of resh air requirement size.During working conditions change, the big I of resh air requirement is set again, according to its corresponding magnitude of pressure differential, regulates return air motorized adjustment valve area and makes that resh air requirement is the steady state value of new settings.
