CAREL is a world leading manufacturer operating in the HVAC/R market offering energy efficient solutions for controls, sensors, Electronic expansion valves, AC & latest DC Speed Drives, Evaporative Cooling, Humidification, Supervisory systems and Energy monitoring.
The 7 Series 700A11 includes these other design features: * Electronic expansion valves employed for optimal refrigerant control.
Modeling Assumptions * The mechanical dynamics of the compressor and the electronic expansion valve are significantly faster than the two-phase heat exchanger dynamics and can be modeled with algebraic relationships.
[ILLUSTRATION OMITTED] According to Master-Bilt, the master controller on the walk-in refrigeration system offers up to 15% energy savings due to the electronic expansion valve and demand defrost feature.
A new electronic controller from Danfoss, used in conjunction with the company's electronic expansion valve, and a plate heat exchanger, can deliver liquid at a temperature or delta-t selected by the user.
In addition, there's demand for component technologies that improve the operational cost or performance of existing HVAC equipment, including variable speed compressors, electronic expansion valves, advanced humidity removal, heat recycling, variable frequency drives, and thermal energy storage.
Electronic Expansion Valve The electronic expansion valve (EEV) used in this study consists of a needle valve controlled by a stepper motor.
Also, electronic expansion valves, rare at this low capacity end of the market, ensure precise capacity control.
