Heating system with heat pump - has efficiency and heat flow measuring system for continuous recording

摘要

The heating system has heat pump which absorbs heat from air or water. This heat is transferred by a condenser into a heating system. The efficiency is directly and automatically indicated or recorded. The system for continuous measurement and recording of the efficiency of the heat pump has drive power absorption meter. The condenser has a heat flow measuring system. Measured values are converted preferably into d.c. signal. A computing circuit is connected to the rate meter and the heat flow meter. Output signal is generated as a ratio of these signals and fed into an efficiency value calibrated voltmeter.
