Test Chambers for Heat Pumps
As countries look to integrate renewable sources of energy into their national electricity grids, heat pumps continue to gain acceptance in many regions as a viable means of controlling indoor temperatures.
Testing of these systems, though complex, is essential to accurately measure a product’s coefficient of performance (COP) and help purchasers make an informed choice. These tests rely on a tightly controlled and stable environment in which the heat pump can operate.
Key Features
- Laminar Airflow
- Airspeed controllable down to <0.5m/s over the product
- Highly stable temperature and humidity control under load
- Responsive to de-frost cycles, etc. to recover condition quickly
- Integration with measurement/test systems
Advantages
Wide Range of Internal Sizes
Internal sizes from 218ltrs to 3000ltrs, to suit your requirement, as well as custom internal size, if required.Wide Temperature and Humidity Ranges
Temperature ranges of +180°C to either -40°C or -70°C are available and even +250°C with our Evaporator Protection feature. Liquid Nitrogen chambers are available with ranges up to +250°C to -100°C. Mechanically cooled chambers can be fitted with humidity covering all areas (10% to 98%RH, 10 to 100°C)High Performance even under Load
Cyclone chambers have a high laminar airflow, providing excellent thermal performance over the whole interior of the chamber, even under densely packed conditions. In addition, the thermal plants are sized to perform under loaded conditions.SIMPLEtouch Programmer
All chambers fitted as standard with our latest SIMPLEtouch programmer for ease of use and a host of features, including remote monitoring &/or control of the chamber using an industry standard MODbus interface.Capacitive Humidity Probe
No maintenance capacitive probes fitted as standard on the temperature/humidity models.Extensive range of Options
Including windows, standard and specially designed ports, product rotation systems, dry-air or N2 feeds, LN2 Boost cooling, glove ports, safety interlock on door, and much more.Suitable for Testing most Standards
Suitable for testing most environmental standards such as IEC 60068, etc.SIMPLEtouch

Sharetree’s range of walk-in chambers can provide the test environment required by a whole range of standards for air-source heat pumps, such as EN 14511 and EN 16147:
- The chamber delivers a gentle, laminar air flow with accurate and precise control of temperature and relative humidity.
- The heat pump takes in this air and extracts its thermal energy.
- This energy is transferred to a water or space heating system and the results are measured to calculate the COP.
Possible testing configurations include:
Single chambers for testing air-to-water heat pumps (for domestic hot water and central heating systems)
Split chambers for testing air-to-air heat pumps (used in smaller properties such as apartments)
