Commercial Variable Refrigerant Flow Retrofit

Variable Refrigerant Flow (VRF) heat pumps have similar applications as Ductless Heat Pumps, though they are more commonly used for multi-zone commercial HVAC applications and are available in larger tonnages. A VRF system cools or heats a space more efficiently than standard systems by moving variable amounts of refrigerant through a piping system to each space independently. Compared with other heat pump systems, VRF systems save energy with better part-load performance, zone control and heat recovery options.

Requirements and Specifications

  • This measure applies to retrofits only.

Preconditions:

  • The project must be pre-approved by CPI.
  • The space is conditioned by zonal or forced-air, electric-resistance heat as the primary heating source. No other heating sources are eligible.

Post-conditions:

The installed VRF system must:

  • Have an AHRI certificate of product rating.
  • Meet BPA’s efficiency requirements for both heating and cooling per the table below.
  • Complete and submit incentive form and invoices to CPI.

The installed VRF system is eligible even if it operates in tandem with a ventilation system that uses any fuel for heating ventilation air.

Incentive Payment: $1,000 per ton
