Abstract

The invention relates to a simulation testing device and a testing method of a central air conditioner automatic control system, and belongs to the technical field of construction energy conservation and automatic control. The simulation testing device and the testing method can achieve tests on basic operation functions, full-automatic operation functions and the energy-saving effect of an object to be tested, and testing is more comprehensive. The simulation testing device and the testing method are achieved by means of a simulation technology, and compared with a traditional testing method, the simulation testing method does not need water system equipment building, is little in investment, little in technical risk, low in operation cost and high in implementability.

Description

technical field [0001] The invention relates to a simulation test device and a test method of a central air-conditioning automatic control system, belonging to the technical field of building energy saving and automatic control. Background technique [0002] At present, building energy conservation has become a hot spot of public concern. The main energy consumption in the building comes from the central air-conditioning system. Facing the rising calls for energy saving, green and environmental protection, the energy saving of the central air-conditioning system has become a trend. In the energy-saving mode of the central air-conditioning system, the application of a fully automatic energy-saving control system to adjust the working status of the equipment according to the cooling demand in real time to achieve high-efficiency and energy-saving operation is an effective and widely applicable energy-saving means, which is being gradually popularized and applied .
