Abstract

The invention relates to an energy consumption measurement technology and aims at providing a method and a device for measuring unit electricity consumption of an ultra-efficient refrigeration station. The device comprises a refrigerating unit, a chilled water pump, a cooling water pump and a cooling tower fan. Temperature sensors are respectively installed on a water supply pipe and a water return pipe of the refrigerating unit, a flow sensor is installed on the water supply pipe or the water return pipe of the refrigerating unit, and an intelligent electric meter is installed on the power supply side of a refrigeration station device. The method and the device has the advantages that the energy consumption of a measurement system is synthesized from the perspective of the system; considering the difference of demands for refrigeration capacity of the refrigeration station of users at different time periods and the influence of external environment change on the system operation efficiency, a concept of energy-saving unit electricity consumption is provided, the energy-saving effect during actual operation can be reflected scientifically and accurately, and the energy-saving effect evaluation can be performed.

Description

technical field [0001] The invention relates to energy consumption measurement technology, in particular to a method and device for measuring unit power consumption of an ultra-high-efficiency refrigeration station. Background technique [0002] In the energy-saving and emission-reduction industry, it is very necessary to scientifically and accurately measure the energy consumption of enterprises. Most of the existing metering methods directly use the total energy consumption difference over a period of time, ignoring the effects of system operating load fluctuations and environmental changes, and lacking the concept of efficiency. [0003] In the process of energy-saving and consumption-reducing transformation of the refrigeration station system, due to the complex coupling effects of each part, simply reducing the energy consumption of each equipment independently may not be able to achieve the best energy-saving effect. The correct way is to consider comprehensively Vari...
