Embodiment Construction

[0041] In occasions where the temperature range changes little, for example, the indoor temperature of a hotel room is generally controlled at 20°C-25°C in winter and 18°C-22°C in summer. Therefore, as long as the input analog quantity is used to control the speed of the fan motor, the optimal combination of energy consumption can be achieved. The control terminals 1, 2, 3, and 4 of the intelligent frequency converter are connected to the potentiometer B, among which the control terminal 3 is connected to the rheostat terminal, and 2 and 4 are connected together, and the terminal 1 is connected to the two fixed terminals of the potentiometer. The motor M is connected to the intelligent frequency converter ECO through wires; the intelligent frequency converter is connected to the main power supply. see figure 1 , 3, 4.

[0042] The basic start-up steps for analog control are:

[0043] (1) Use an electronic thermometer to observe the temperature change in a certain room.

Abstract

The present invention disclosed an intelligent electricity-saving equipment capable of making electricity-saving rate be up to above 50%. Said equipment adopts the following measures: following and detecting refrigerating output of compressor, making circulating water flow and refrigerating output retain real time adaptation, automatically detecting environment parameters, automatically changing rotating speed of flower fan, making the temperature in the air-conditioning area be retained in set value, reducing machine noise and making variable frequency control of water pump motor, etc.

Description

technical field [0001] The invention relates to an electricity-saving equipment, in particular to an intelligent energy-saving equipment which utilizes an intelligent frequency converter to make each motor of a central air-conditioning system operate at its maximum efficiency. Background technique [0002] Taking the central air-conditioning system of most hotels and restaurants as an example, the cooling capacity of the central air-conditioning compressor is adjusted by using the opening of the air inlet door or the way of smooth bypass. Under partial load conditions, the energy of the unit Both the value and the power factor of the motor are greatly reduced; the adjustment of the circulating water volume of the central air conditioner is realized through gate valves, but in actual operation, these valves are actually all open, so that the water system is in a long-term "large flow, small temperature difference" abnormal state. In recent years, frequency converter speed re...
