Generally speaking, water system central air conditioner main machine (centrifugal refrigerating machines for example, the wind-cooling type heat pump unit, water source heat pump units etc.) control and air-conditioner tail end equipment capable (fan coil units for example, air-treatment unit etc.) control is separate, the switch of air-conditioner tail end equipment capable and adjusting are with the foundation of indoor air temperature as control, and central air conditioner main machine is with the supply water temperature of air-conditioner circulating water or the return water temperature foundation as control, architecture indoor air conditioner cold-warm demand is not invariable, with personnel, the interwovenesses such as outdoor temperature, can say, the indoor changes in temperature demand is not changing all the time, current central air conditioner main machine adopts fixed water supply or return water temperature work mostly, removes the non-manual corresponding setting value of going to revise.Summer is when freezing, if it is low that the air-conditioning water temperature was set, at weather not too hot or personnel not many in, cause cold superfluous, easily produce condensed water, and it is huge to consume energy, too high if the air-conditioning water temperature is set, at weather hotter or personnel more in, the air conditioning terminal poor refrigerating efficiency does not reach the effect of design; In like manner, during heat supply in winter, too high if the air-conditioning water temperature is set, at weather not too cold or indoor occupant intensive in, cause the room overheated, comfortableness is poor, and it is huge to consume energy, and is low if the air-conditioning water temperature was set, at weather colder or indoor occupant rare in, cause the air conditioning terminal radiating effect poor, indoor temperature is on the low side, and comfortableness is poor.

The utility model content

The technical problems to be solved in the utility model provides a kind of central air-conditioning Dynamic Water temperature control system, according to outdoor environment temperature dynamic adjustments air conditioner water supply water temperature, guarantees the comfort level of indoor environment, and has reduced energy resource consumption.

The technical solution of the utility model is:

Central air-conditioning Dynamic Water temperature control system, the Dynamic Water temperature controller that include central air conditioner main machine, be arranged at air-conditioner host controller in the central air conditioner main machine, is connected with the air-conditioner host controller and the air-conditioner tail end equipment capable that is connected with outfall sewer with the water inlet manifold of central air conditioner main machine, described central air-conditioning Dynamic Water temperature control system also includes and is arranged in the outdoor environment and the outdoor environment temperature sensor that is connected with the Dynamic Water temperature controller.

Be respectively arranged with water inlet manifold temperature sensor and outfall sewer temperature sensor on the water inlet manifold of described central air conditioner main machine and the outfall sewer, and water inlet manifold temperature sensor and outfall sewer temperature sensor all are connected with described Dynamic Water temperature controller.

Described air-conditioner tail end equipment capable is many, and every air-conditioner tail end equipment capable all is connected with outfall sewer with the water inlet manifold of central air conditioner main machine.

Advantage of the present utility model:

The utility model takes full advantage of intelligent control technology, first, can revise in conjunction with air-conditioning work at present pattern, the real-time working moment, real-time outdoor environment temperature, system's work-load rate etc. the operating temperature of central air-conditioning water circulation, optimize the heat transfer effect of air conditioning terminal, promote comfortableness; The second, can realize the dynamic energy-saving control of Air-conditioning Cycle water temperature, at utmost reduce the air-conditioning units consumption, not only in air-conditioning equipment, can adopt, but all extensive uses in the cold and heat source system of the other types such as boiler heating, city central heating; The 3rd, the utility model regular stronger occasion such as be suitable for handling official business, employing timetable control rapid and convenient has been avoided staff's frequent hand-guided.
