Abstract

The invention relates to an energy-saving control method of a central air-conditioner. When a heat source of an air-conditioning system is in the starting process, the rotation speed of a heat source water pump is determined according to temperature monitored by a temperature measurement device on an outlet side of the heat source and a temperature measurement device on an inlet side of the heat source in real time, and the rotation speed of a cooling water pump is determined according to the temperature monitored by a cooling water temperature detection device on the outlet side and a cooling water temperature detection device on the inlet side in real time. When a temperature value measured by the temperature measurement device on the inlet side of the heat source in a refrigeration mode is lower than a set temperature lower limit or the temperature value measured by the temperature measurement device on the outlet side of the heat source in a heating mode is higher than a set temperature upper limit, a controller sends a stop instruction to the heat source, the heat source stops running, the rotation speed of the heat source water pump is controlled to be the lowest rotation speed for starting of the heat source, a cooling water pump is controlled to stop running, and moreover, the heat source water pump can be controlled to stop running. Accordingly, energy can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of an air temperature adjustment control system, in particular to an energy-saving control method for a central air conditioner. Background technique [0002] High-rise buildings mainly use central air-conditioning systems for ventilation and temperature regulation. In existing central air conditioners, no matter what state the heat source is in, all heat source water pumps and cooling water pumps run at full load at a fixed frequency, resulting in waste of energy for driving the water pump motor; because the water pumps are running at full load regardless of the actual load, this It leads to excessive reactive heat exchange at the end, and the heat source needs to provide these heats, resulting in waste of energy consumption of the heat source. When designing and selecting the air conditioning system, the motor driving the water pump is generally selected based on the principle of 20% higher than the requi...
