DEVICE FOR LABORATORY RESEARCH TO DETERMINE HEAT-TRANSFER APPARATUS THERMAL CHARACTERISTICS

摘要

The device for laboratory research to determine heat-transfer apparatus thermal characteristics relates to electrical engineering. The device consists of a heat-transfer apparatus, a cold heat medium source, a hot heat medium source connected among them with valve conduits and measurement devices. It is arranged as a pattern or a painting on stand panel and it includes additionally some heat-transfer apparatus samples with various characteristics, some heat-transfer apparatus source and an electric block. The electric block consists of some fixed and variable resistor standard-voltage divider groups to form instrument parameter values, switches and electrical measurement devices. Herewith for each heat-transfer apparatus separate standard-voltage divider groups to connect with corresponding groups of operation mode setting switch contacts, the outputs being connected through heat-transfer apparatus sample choice switches with measurement devices for indexing parameters. The device provides informativeness broadening, essentially decreases its maintenance costs and multivariant laboratory research enhances its application.
