Abstract

The invention relates to a device for testing thermal balance of a gas cooker, solves the problem of measurement of energy loss in novel cooker design, and provides support for improving cooker design and reducing energy loss. According to the device, based on a combustion principle, by measurement of hot water temperature, smoke component analysis, radiation intensity and temperatures of upper and lower ends of a furnace end, effective heat absorption energy, smoke loss energy, radiation loss energy, and heat conduction loss energy are estimated. By measuring gas flow, total energy of gas consumption is estimated. Thus a main energy consumption proportion of a tested cooker can be obtained, thereby providing test data support for further improving cooker design. The device for testing thermal balance of the gas cooker in the invention adopts computer measurement and control technology, and achieves the effect of automatically realizing signal acquisition, data processing and data management functions. And automated testing of cooker energy conversion and distribution is realized.

Description

technical field [0001] The invention relates to a heat balance test device and method of a gas cooker, and is an automatic test device and a calculation method for estimating energy efficiency and heat loss of a gas cooker. It belongs to the technical field of thermal measurement and control. Background technique [0002] During the development process of domestic gas cookers, it is necessary to guide the design and transformation of domestic gas cookers by estimating indicators such as smoke exhaust loss, radiant heat loss, heat conduction loss, and effective heat absorption. [0003] At present, the national standard GB16410-2007 stipulates the test method for the effective utilization rate of household gas stoves. However, the measurement methods of exhaust smoke loss, radiation heat loss and heat conduction loss are not given. Because there are no sensors for directly measuring exhaust smoke loss, radiant heat loss, and heat conduction loss, there is no such device at...
