Description
Technical field
The utility model relates to air conditioner energy saving technical field, is specifically related to air-condition freezing water energy-saving system.
Background technology
Current air-conditioning kind is on the market a lot, fixed frequency, frequency conversion etc., but most air conditioner energy saving effect is still not good, can not reaching to the object of user's power saving, because air-conditioning does not possess the function of Energy Saving Control when running, change can not be regulated according to the change of load, this considerably increases the power of operation of air conditioner, result of use can not reach best.
Utility model content
For solving the problem, the utility model provides air-condition freezing water energy-saving system, and structure is simple, can be in best running status by air-condition freezing hydroelectric machine, ensure that the effect of operation of air conditioner, efficient energy-saving.
For achieving the above object, the technical scheme that the utility model is taked is: air-condition freezing water energy-saving system, comprise temperature difference adjuster, PLC, frequency converter, first motor, second motor, chilled water pump unit, evaporimeter and temperature difference feedback device, temperature difference adjuster is connected with PLC, PLC respectively with frequency converter, second motor is connected, frequency converter is connected with the first motor, first motor is all connected with chilled water pump unit with the second motor, chilled water pump unit and evaporimeter and user are linked to be a loop, the outlet pipe of evaporimeter is connected with temperature difference feedback device with return pipe, temperature difference feedback device is connected with temperature difference adjuster.
As preferably, the outlet pipe of described evaporimeter and return pipe are provided with the speed changer of detected temperatures.
The utility model has following beneficial effect: structure is simple, can be in best running status by air-condition freezing hydroelectric machine, ensure that the effect of operation of air conditioner, efficient energy-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model embodiment provides air-condition freezing water energy-saving system, comprise temperature difference adjuster 1, PLC 2, frequency converter 3, first motor 4, second motor 5, chilled water pump unit 6, evaporimeter 7 and temperature difference feedback device 8, temperature difference adjuster 1 is connected with PLC 2, PLC 2 respectively with frequency converter 3, second motor 5 is connected, frequency converter 3 is connected with the first motor 4, first motor 4 is all connected with chilled water pump unit 6 with the second motor 5, chilled water pump unit 6 and evaporimeter 7 and user are linked to be a loop, the outlet pipe of evaporimeter 7 is connected with temperature difference feedback device 8 with return pipe, temperature difference feedback device 8 is connected with temperature difference adjuster.
It should be noted that the speed changer outlet pipe of described evaporimeter and return pipe being provided with detected temperatures.
The system water temperature of this detailed description of the invention depends on the setting value of evaporimeter, return water temperature depends on the heat that evaporimeter receives, it is 5 DEG C (water outlet is 8 DEG C, and backwater is 13 DEG C) that the return water temperature of the temperature that air conditioning water goes out and chilled water designs maximum temperature difference.Native system adopts the transmitter that detected temperatures is housed on the outlet pipe and return pipe of evaporimeter, closed-loop control system is formed again with PID thermoregulator, PLC and frequency converter, controlled by the temperature difference of chilled water, the rotating speed of chilled water pump unit is changed corresponding to the change of heat load, when First motor has reached power frequency, also do not reach when requiring and just can start second motor, power frequency operation, then regulate and control First motor.So continuous adjustment controls, and makes it reach best effect.
This detailed description of the invention structure is simple, can be in best running status by air-condition freezing hydroelectric machine, ensure that the effect of operation of air conditioner, greatly saved electric energy.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
