Abstract
The utility model discloses an energy efficiency control management system of a central air conditioner. The energy efficiency control management system of the central air conditioner comprises a frequency converter (8) which is connected with a pump set (14), and a controller (7) which is connected with the frequency converter (8), wherein a water supply temperature sensor (12) and a water supply pressure sensor (13) are respectively arranged on a water supply pipe; a water return temperature sensor (3) and a water return pressure sensor (4) are respectively arranged on a water return main pipe (2); and the sensors are respectively connected with the controller (7). Temperature and pressure values in water supply and return pipelines of the central air conditioner are acquired in real time and then compared with set temperature and pressure values in the controller. When the acquired values exceed the range of the set values, the output power of the pump set of the air conditioner is timely adjusted, so the aim of saving the power of the whole system is fulfilled.
Description
Technical field
The utility model relates to a kind of control and management system of central air-conditioning.

Central air conditioner system be one multivariable, complicated, the time system that becomes, exist serious non-linear, large time delay and close coupling relation between its process element.To such system, no matter control with classical PID, or the various algorithms of modern control theory, all be difficult to realization and control preferably effect.
The utility model content
Technical problem to be solved in the utility model is, a kind of central air conditioner energy efficiency control and management system is provided, entreat the air-conditioning system parameter to carry out complete sampling according to the variation of air conditioner load and the operating condition automatic centering of air-conditioner host, regulate and control at any time the pump group, make air-conditioning system follow the variation of load and change, reaching energy-conservation purpose.
The technical solution of the utility model is as follows:
A kind of central air conditioner energy efficiency control and management system, the main frame that comprises central air-conditioning, be used for driving pump group and several mutual refrigeration terminals in parallel of host work, the water end (W.E.) that supplies of described main frame is connected with water storage box by the first feed pipe, the water side of water storage box connects described refrigeration terminal, comprise that also an end connects described refrigeration terminal, the other end connects the return main of described main frame, it is characterized in that: also comprise the frequency converter that is connected with described pump group and the controller that is connected with frequency converter; Be separately installed with supply water temperature sensor and pressure of supply water sensor on described the first feed pipe, be separately installed with return water temperature sensor and pressure of return water sensor on described return main; Described supply water temperature sensor, pressure of supply water sensor, return water temperature sensor and pressure of return water sensor are connected with described controller respectively.
Described controller also is connected with display.
Good effect of the present utility model is: by confession, the temperature in water return pipeline, the force value of Real-time Collection central air-conditioning, compare with temperature, the force value set in controller.In time adjust the power output of air conditioning pump group when the collection value exceeds the regional extent of setting value, thereby reached the economize on electricity purpose of whole system.And show the real time data of relevant parameter by display, be convenient to administrative staff and take the administration of energy conservation measure.
Use control and management of the present utility model system, according to the different situations of various building central air conditioner systems, the energy-conservation 5%-20% of central air conditioner main machine.Extended simultaneously service life of equipment.
