Mechanical principle of air conditioning pump
Mechanical principle of air conditioning pump
By the temperature, ventilation, air conditioning pump pressure sensor system, PLC control system, variable frequency speed regulation system, touch screen system and cold (heating) or cooling water pump of closed loop control system, the temperature difference and pressure difference of the feedback value and setting the target value of comparison, through the operation of the PLC system automatically adjust the water pump frequency, maximum on the premise of meet the technical requirements to achieve the goal of saving electricity.As the change of working condition of equipment control water pump motor frequency times in under the premise of satisfying need change, because of the frequency decrease, noise, the motor temperature drop, namely save electricity and prolong the service life of the equipment, the resulting economic benefit and social benefit are considerable.According to this principle, IAO the zanu-pf - I type electricity-saving control device of automatic adjustment control pump start-up and speed, increase temperature difference to the specification range or meet the actual requirements of scope, reduce the pump flow, so that the water pump motor corresponding to reduce power consumption, to achieve a significant power saving.Application limitations:
IAO PF - I type energy saving control device is not suitable for the central air conditioning system into the return water temperature difference and heat exchange system has large and close to the national standard of 5 ℃.
The power consumption expression of the pumping station N= K 1 * Q * H/eta, except that the iao-pf-i-type introduction increases the temperature difference and decreases the flow rate of the pumping station
Head (pressure) H can reduce the power consumption of the pumping station control method, it also can be to enhance the overall efficiency of the pumping station eta to reduce the power consumption, national high technology industrialization of major projects - quantitative pump station energy saving system, through the system optimization, under the meet the technological requirements, according to the power consumption
The low pump group optimizes the collocation and the speed regulating operation control equipment, realizes the quantitative energy saving control of the pump unit, can make the pump station achieve the transportation that can realize
The maximum efficiency of the line is eta Max, which can achieve significant energy saving even if the central air-conditioning system does not exist.
The IAO- pf-i type quantization control equipment of air conditioning pump is applicable to all central air conditioning systems, regardless of whether there is a temperature difference or no temperature difference
The equipment can also be used to transform the pumping stations (groups) of the existing frequency and other energy saving devices to achieve the maximum power saving.IAO PF - i.
The type quantification control device can make the refrigeration pump, cooling pump and heating pump group of central air conditioning system to save energy.
