Projects

HPT TCP has been active since 1978, with a lot of collaborative research, development, demonstration and deployment projects. We formerly called these projects "Annexes". They are conducted on a combination of cost sharing and task-sharing basis by the participating countries. Here you can read about the projects that are running right now.

A Common Method for Testing and Rating of Residential HP and AC Annual/Seasonal Performance

To achieve an excellent working heat pump system, the right type of heat pump must be chosen and installed with a matching heat distribution system. For this reason, it is important to have reliable information on both the heat pump itself, and how it is influenced by the surrounding system. Objectives The main objectives of the Annex are: Establish common calculation methods for SPF using a generalised and transparent approach. The focus is on a...

Solar and Heat Pump Systems

A joint project with the IEA “Solar Heating and Cooling” Implementing Agreement (SHC) Task 44 Annex 38 was concerned with solar and heat pump system for space heating and domestic hot water. A total of 55 experts from eleven countries attended some or all of its eight meetings over the period 2010 – 2013. Objectives The objective of this Task was the assessment of performances and relevance of combined systems using solar thermal and heat...

Demonstration of Field Measurements of Heat Pump Systems in Buildings - Good Examples with Modern Technology

There is a need to be able to demonstrate the potential for energy savings and CO2 reduction with heat pump technology. There is also a need for increased knowledge of the efficiency of heat pumps in real installations, especially concerning heat pump systems for combined operation including heating, cooling and domestic hot water production. Objectives The objective was to demonstrate the potential with heat pumping technology for all types of buildings from existing field measurements....

Quality Installantion/Quality Maintenance Sensitivity Studies

It is widely recognised that residential and commercial heat pump equipment suffers significant performance loss (i.e. decreased capacity and efficiency), depending on how the components are sized, matched, installed, and subsequently field maintained. This Annex evaluated how installation and/or maintenance deficiencies cause heat pumps to perform inefficiently and waste energy. Specifically investigated were the extent that operational deviations are significant, whether the deviations (when combined) have an additive effect on heat pump performance, and whether...

Thermally Driven Heat Pumps for Heating and Cooling

The goal of Annex 34 was to reduce the environmental impact of heating and cooling by the use of thermally driven heat pumps. It was based on the results from Annex 24, ”Absorption Machines for Heating and Cooling in Future Energy Systems”, and cooperated with the IEA-SHC task 38, “Solar Air-Conditioning and Refrigeration”. Objectives One of the main objectives was to quantify the economic, environmental and energy performance of integrated thermally driven heat pumps in...

Compact Heat Exchangers in Heat Pumping Equipment

This Annex was directed at widening the use of compact heat exchangers (CHEs) in heat pumping systems. The Annex wanted to show that these can improve efficiencies, minimise fluid inventories and reduce package size. The annex collected data during to quantify the possible benefits from CHE use, and also highlight any concerns. Objectives The objective of this Annex was to present a compilation of possible options for compact heat exchangers, used as evaporators, condensers and in other roles in...

Economical Heating and Cooling Systems for Low Energy Houses

This Annex investigated different configurations of integrated multifunctional heat pump systems for space heating, DHW production, space cooling, ventilation and de-/humidification of the ventilation air for the application in low and ultra-low energy houses. Objectives The objective was to evaluate, assess and enhance integrated heat pumps systems for low energy houses with regard to overall energy use and costs under the boundary conditions of thermal comfort.

Advanced Modeling and Tools for Analysis of Energy Use in Supermarkets

Supermarkets are the most energy intensive buildings in the commercial sector. It has been estimated that 3-5 % of the total use of electricity stems from supermarkets in industrialized countries. The energy systems are complex and large efficiency improvements are possible if a better understanding of design and operation of these systems can be acquired. In addition, it is estimated that the annual refrigerant losses are as high as 15 – 30% of the total...
