The Hench Control Energy Management System is exclusively designed and manufactured in-house. The system is comprised of proprietary equipment that is conjoined with a sophisticated and extensive high-level programming language specifically for industrial refrigeration. The foundation of the system is specific for the purpose of reducing the energy requirements for the operation of compressors, condensers, evaporators and peripheral refrigeration equipment. In effect, the principal result is the reduction of energy used with regard to horse power (HP). To calculate energy savings, the Energy Management System uses proprietary formulas driven by thermodynamics and the physics relating to the system’s ability, performance, physical environment and atmospheric changes at any industrial refrigeration facility.
The system has the ability to operate at a basic level to provide simple operational controls without using any of the energy management components as one of the ways in which the system proves itself. With the use of a metering device such as a Power Pulse Meter and/or Current Indicator, the system will confirm the disparity between a standard control system and one driven by the energy management principles.
There are three main rules the system follows:
1. For every 1psig that the Low Stage Suction Pressure is raised, the system will save about 2% on the total HP in use.
2. For every 2psig that the Discharge Pressure is lowered, the system will save about 1% on the total HP in use.
3. Every facility will change its thermodynamic balance every moment of operation depending on demand, mass, atmospheric variances and process criteria.
From these major energy savings “rules,” the system derives and compounds other rules and formulas to achieve savings. The formulas and basic rules are the foundation of the Energy Management System. To achieve and maximize energy savings, the following procedures below need to be paradigm in nature.
With proper placement and calibration of Temperature sensors the system can:
With the equipment installed and calibrated, then the system can optimize.
