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 invention discloses an intelligent power-saving device. Using the intelligent frequency converter, according to the working object of the central air-conditioning system and the change of the ambient temperature range, the program parameter setting is used to control the needs of various motors in different occasions. When the parameter setting value is reached, the control system will automatically optimize. Motor energy consumption, so that the motor is always running at the maximum possible efficiency. It not only reduces energy consumption, but also reduces noise. The invention tracks and detects the cooling capacity of the compressor, so that the circulating water flow and the cooling capacity can be matched in real time, and the annual average power saving rate can reach more than 42%. Through automatic detection of environmental parameters, Automatically change the speed of the fan to keep the temperature in the air-conditioning area within the set value, which not only reduces the noise of the machine, but also saves electricity by more than 50%. The frequency conversion control of the water pump motor reduces the impact of the motor on the power grid and prolongs the use of equipment It has the characteristics of high efficiency, energy saving and low noise.

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...
