Thermal Products

The Delphi Micro Channel Heat Pump Coil is being developed to provide a cooling function when used in a warm ambient environment and a heating function when used in a cold ambient environment. It will be able to be used in residential, rooftop, and many commercial applications.

The Delphi Micro Channel Heat Pump Coil design will allow it to operate efficiently in both condensing (cooling) and evaporating (heating) modes. In heating mode, the heat pump coil is designed to operate in temperatures ranging from sub-freezing up to 60°F (15°C). In situations where the ambient temperature is only slightly above freezing and the coil could be subjected to frost, the coil will operate in a frost-removal mode.

The design leverages Delphi's 25 years of experience developing micro channel heat exchangers for automotive air conditioning systems. That same experience and expertise back Delphi's complete lineup of Stationary and Transport Air Conditioning/Refrigerant (STAC/R) products. They include the Delphi Micro Channel Condenser and Delphi Micro Channel Evaporator.

Delphi produces more than 37 million heat exchangers every year. A suite of proprietary testing systems provides the ability to model components as well as entire systems. Delphi's heat transfer simulation capabilities help ensure an optimally designed system for nearly any application.

Benefits

• High efficiency
• Helps original equipment manufacturers meet high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) requirements
• Aluminum construction yields high durability and is easy to recycle
• Substantial refrigerant charge reduction compared to tube and fin designs, enhancing environmental friendliness and helping reduce operating costs
  

Typical Applications

The Delphi Micro Channel Heat Pump Coil is suited for use in:

• Residential air conditioning/heating (outdoor units)
• Commercial cooling/heating applications, including chillers and rooftop units
• Heating units

Performance Advantages

The Delphi Micro Channel Heat Pump Coil, like all Delphi STAC/R products, is constructed of brazed aluminum and is based on the innovative Micro Channel Heat Exchanger (MCHX) technology, which consists of three components:

• A flat micro channel tube
• Fins
• Two refrigerant manifolds joined together in a single coil

The design provides greater efficiency than traditional mechanical tube and fin heat exchanger designs.
