AI Technical Summary
Existing cooling devices for oil-injected compressor devices are limited by fixed switching temperatures in thermostats, leading to suboptimal oil cooling, pressure drops during startup, and risk of condensate formation due to reliance on worst-case scenarios and energy recovery systems.
A cooling device with a variably adjustable first electronic thermostat and optional second thermostat, allowing dynamic control of oil flow through an energy recovery system and oil cooler based on real-time operating conditions, eliminating the need for fixed switching temperatures and ensuring optimal oil temperature without condensate formation.
Ensures the oil is cooled to the lowest possible temperature without risking condensation, reduces pressure drops, and improves compressor performance and longevity by adapting to actual operating conditions.
