"HEAT-COLD" SYSTEM FOR AUTOMOBILE WITH HEAT-INSULATED VAN Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to cooling of working volumes of insulated bodies installed on vehicles. "Heat-cold" system for automobile with heat-insulated van contains cooling system, heater and control system. Novelty is that system is furnished with thermal energy sources on form of thermoelectric heating elements installed inside evaporating unit of cooling system and supplied with energy from additional generator installed in hood space of automobile. Said additional generator and compressor of cooling system are driven from one pulley by V-belt drive. Used as additional generator is 12-Volt dc generator of automobile transformed into three-phase 40-Volt ac generator by removing of voltage regulator and diode bridge from dc generator. Windings of generator can be delta or star-connected and insulated from ground.

EFFECT: improved efficiency and economy of cooling and heating system of heat-insulated bodies, reduced overall dimensions and enlarged operating capabilities.
