Problems solved by technology

[0013] First, the above-mentioned multiple air conditioners 30#1,....30#n are installed in the same place. Therefore, most of the air conditioners are performing cooling/heating operations at the same time, especially when the air conditioners are in peak use. Electricity consumption rises for air-conditioning units
Once the power consumption exceeds the specified power value on the transformer, the power supply to the air conditioner group 30#1,...30#n will be

Example Embodiment

[0035] The present invention provides a central management method for a multi-room air conditioner. One embodiment of the method is carried out in the following stages: current detection and monitoring stage: the current value of the power consumption is detected, and whether the detected current value exceeds the set value is monitored The current monitoring phase of the specified current value; control phase: when the current value detected by the monitoring exceeds the specified current value, the control phase of reducing the operating capacity of all air conditioners currently in operation; in the control phase, the adjustment of the operating capacity is in the detection The output current value is adjusted within the range of not exceeding the specified current value.

[0036] Another embodiment of the method is carried out in the following stages: current detection and monitoring stage: the current monitoring stage in which the current value of the power consumption is det...

Abstract

The invention provides central management methods for multi-room air conditioners. A method includes current detecting and monitoring stage and control stage. In the control stage, running ability is regulated as the detected current value does not exceed specialized range. Another method includes current detecting and monitoring stage and control stage. In the control stage, when stop time of an air conditioner exceeds the set time, the air conditioners in halted state and in operational state are repeatedly converted. The beneficial effect of the invention is: the peak electric power value rise can be inhibited, and the electric quantity overload problem can be solved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a central management method for a multi-room air conditioner. Background technique [0002] In public places such as schools and companies, there are multiple separate spaces. Air conditioners are installed in these separate spaces to adjust the temperature and temperature of the space. Since the air conditioners in each space are installed in the same place, they are powered by one power line. [0003] Such as figure 1 As shown, the connection structure of air conditioners installed in the same place in each space includes: setting multiple air conditioners 30#1,....30#n on the same power line L1, L2; detecting the current value passing through the power lines L1, L2 And monitor the transformer 10 that exceeds the specified current limit value set; according to the sensed value of the transformer 10, cut off the relay 20 that supplies power to multiple air conditioning units 30#1, ... 30#n...
