National project:

Introduction
The Austrian participation in the IEA HPP Annex 28 refers to both the development of a test procedure and a calculation method.
In Austria, a research focus in the field of heat pumps is the development of direct expansion heat pumps. This type of heat pumps is available on the Austrian market from several manufacturers for many years and their market share is about 45%.
Test procedure
The test procedure, which will be developed, is based on the existing standards EN 255-2 and EN 255-3. To test heat pumps with combined space heating and domestic hot water operation these standards are not applicable as this mode of operation as well as the type of direct expansion heat pumps is unaccounted for these standards.
Therefore a test procedure for direct expansion heat pumps with combined space heating and domestic hot water operation will be developed by the Austrian team based on measurements and monitoring direct expansion systems with desuperheating for DHW production.

Calculation method
The calculation method is based on a bin approach as described by the Swiss team. The task of the Austrian team is the evaluation of the proposed standard for the calculation of the seasonal performance factor heat pumps with combined space heating and domestic hot water operation for of direct expansion heat pump systems.
As for the proposed calculation method a function describing the correlation between the source temperature and the air dry bulb temperature is required, a special focus will be put on this aspect for direct expansion systems and ground coupled systems in general.
