Improved Efficiency for Heat Pump Water Heaters in Cold Weather

Request Number N572759
Author Kevin Andrews
Need details
Description

Haier seeks technology that will improve the efficiency of heat pump water heaters when ambient temperatures are <-25°C.

 

Background

 

 

Since heat pump water heaters essentially transfer heat from the air to water, their efficiency drops significantly during cold weather months.  Haier seeks technology that can reliably improve the performance of heat pump water heaters when the ambient temperatures fall below -25°C.


 

 

Key Success Criteria

Successful responses will:

  • Be able to produce hot water (65°C) when ambient temperatures are <-25°C
  • Have a Coefficient of Performance (COP) of at least 2.0 when the ambient temperature is under -20°C
  • Have a COP of at least 3.4 when the ambient temperature is over 20°C

 

Possible Approaches
  • Two stage compression
  • Enhanced vapor injection

 

Approaches not of interest
  • Electrical boosting

 

Preferred Collaboration types
  • Joint Development
  • Contract Research
  • Supply Agreement
  • To Be Negotiated
Items to be submitted

Preference will be given to technologies or approaches that currently have working prototypes that can undergo feasibility, validation or proof of concept over a 3-6 month period. Financial support for the proof of concept phase will be negotiated based on specific performance targets agreed between both parties. For selected collaborators Haier may provide access to samples, test equipment and testing facilities. Technologies will need to satisfy manufacturability, material cost and ease of use assessments to progress from the concept stage.

 

Haier prefers to work with partners that have existing technologies or approaches that can be applied to this specific application. Collaboration can involve technology licensing, product sourcing, proof of concept leading to joint development & assistance with scale-up to manufacturing.

 

We are looking for concise non-confidential proposals, statements of expertise or other enquiries if your expertise fits our needs. Please note that only non-confidential information can be accepted. The proposal should also provide us with appropriate contact information in order to help us keep update with solution providers. .

 

For all responses please indicate your preferred collaboration approach (eg supply, joint development, research) and capabilities (eg research, concepts, prototype, small scale manufacture, large scale manufacture).

 

We welcome responses from companies (large or small and medium enterprises), technical experts and academic or industrial researchers, inventors and venture capitalists.
