Inexpensive EMS For Packaged HVAC Can Save 20%

Packaged HVAC is Inefficient

  • Packaged, split and heat pump units generally
    turn on and off based solely on fixed set points.
  • A unit limited to on/off control operation has no
    EMS capability and can’t modulate HVAC.
  • These type units are generally energy hogs and
    often can waste up to 20% energy cost.

The On Premise Family of Controls are used by businesses of all kinds who want to control their lighting and HVAC costs including convenience stores, fast food restaurants, gas stations, hotels, banks, shopping malls, and property management companies.

Conquest's Savings Methodology

  • Conquest is a microprocessor that analyzes conditions affecting energy demand every cycle.
  • Conquest shuts compressor off prior to reaching set point, based on:
    • The level of expected ‘overshoot’ under
      the real-time demand condition.
    • Thermal inertia that causes space to lose
      or gain temperature slowly.

Energy Savings Opportunity

  • Compressor run time reduces 10% to 20%.
  • Thermostat keeps space in set-point range, as
    Conquest will not affect on-cycle call.
  • Payback is typically 9 to 18 months.

Installation and Protections

Sealed, maintenance-free unit is wired into the low voltage control circuit between the thermostat and the main contactor controlling HVACR, and can be installed in less than one hour. Conquest Cycle Manager shortens on-cycles only after a minimum of 3.5 minutes on-time, to avoid “short cycling” compressor wear.

Conquest HVAC Performance Test Data

  • Conquest was installed on two 40-ton HVAC units.
  • Data loggers sampled current every 8 seconds.
  • Run time was measured with Conquest on and off during alternate weeks.
  • Data from two-hour periods, below, demonstrate reduced run time.
