National project

In the US team three institutions are involved and will work on the following projects:

Oak Ridge National Laboratory (ORNL) has several integrated heat pump (IHP) systems developments. An electric ground-source (GS-IHP) and air-source (AS-IHP) versions and an engine driven AS-IHP version will be developed through a field demonstration testing stage. The first commercial GS-IHP product was introduced to the market in December 2012. This work is a contribution to Task 3 of the Annex.

The University of Maryland will contribute a software development project to Task 2 of the Annex. The software ThermCOM is to evaluate thermal comfort accounting for all radiative and convective heat transfer effects as well as local air properties.

The National Institute of Standards and Technology (NIST) is working on a field study effort on the NIST Net Zero Energy Residential Test Facility (NZERTF). This residential building was constructed on the NIST campus and officially opened in summer 2012. During the first year, approximately between October 2012 and September 2013, baseline performance of the NZERTF and all appliances will be monitored under a simulated occupancy protocol. During the first (baseline operation) year the house will be equipped with an ultra-efficient, air-to-air heat pump. Outdoor conditions, internal loads and modes of heat pump operation will be monitored. Field study results with respect heat pump operation will be reported and recommendation on heat pump optimization for a net-zero energy building will be provided. This work is a contribution to Task 3 of the Annex.

US technical contributions related to Task 4 of Annex 40 will mostly be related to the parallel work under the Annex 42 entitled heat pumps in smart grids and reported in Annex 40.
