The SolabChiller developed by SolabCool uses excess heat to provide energy-efficient cooling. Water is used a natural coolant to distribute the cooling within private housing or small commercial applications. The SolabChiller is a compact cooling system that operates on the principle of sorption cooling. It uses excess heat from district heating networks, solar power generators or combined heat and power systems – energy that would otherwise be lost. The SolabChiller has a 75% lower electricity consumption compared to conventional air conditioning systems, hereby greatly reducing operating costs and carbon emissions. The SolabChiller has a thermal efficiency of 6 and is available with a maximum power of 2.5 or 5 kW, dependent on the type of cooling requirement. …

Working with academic institutions across Europe, Solar Polar have developed off-grid solar thermal powered absorption cooling systems for air conditioning, refrigeration for vaccines and food storage purposes. The cooling systems may be mounted on the roofs or walls of buildings or even in open spaces. Several appliances may be joined together to satisfy the required cooling load, especially in regions prone to prolonged periods of cloud cover. …

ZIEGRA Ice Machines from the propane (R290) CoolNat series use battery-buffered solar power to supply ice for food preservation, such that they are ideal for use in regions that have no or very unreliable power supply. …

Global Technological Breakthrough for Solar-Powered Vaccine Coolers Driven by the International “SolarChill Partnership" in Terms of Storing Vaccines in Areas without Regular Power Supply. The Vestfrost SolarChill vaccine refrigerator with the Secop Solar Compressor was the first device to be tested and approved by WHO. Since then, Vestfrost Solutions has delivered a significant number of refrigerators for vaccine programs all over the world. …

The STRATOS series from Secon is the flagship among the air-cooled propane chillers. The series covers cooling capacities from 150 to 1,200 kW and can be used in a wide temperature range with discharge temperatures from +20 to -30°C. As standard, the units can be operated at ambient temperatures from -20 to +40°C (tropical version available on request). LT models use propylene (R1270), which is also a natural refrigerant. The units can be equipped with 1 to 4 reciprocating pistons or 1 to 2 screw compressors. The capacity control is either stepped or stepless with inverters. The units already have a special, highly developed control system as standard. Optionally, they can also be equipped with a Siemens S7 industrial control system. All units are designed specifically for the project and can be equipped with various options (pumps and/or hydraulic modules, heat recovery or free cooling). …

The Electrolux SC300 is a completely F-gas free domestic refrigerator. The energy efficient system uses R600a and is rated with A+++ for the European Energy Index. The SC300 only uses around 71kWh per year. A quick-cooling function, attractive LED lighting and the spacious SpacePlus drawer offers a user-friendly and efficient cooling solution for your domestic needs. …

All basic components for thermal cooling are included in one device: Invensor’s LTC 30e Plus. With a maximum thermal coefficient of performance (COP) of 0.72 and an outstanding maximum energy efficient ratio (EER) of 33, the LTC 30e Plus remains one of the most energy efficient chillers on the market. An automatic power adjustment allows cooling capacity ranging from 10 to 35 kW. With an integrated system controller, the LTC 30e Plus provides a range of options to meet individual customer needs and applications. The system is controlled remotely via ethernet, and comprehensive measurement technology facilitates installation and operation. A hydraulic unit with powerful high-efficiency pumps directly connects all hydraulic circuits for the driving energy, cooling distribution and recooling. …

In cooperation with Transfrig, the only South African manufacturer of transport refrigeration systems, GIZ South Africa has completed field testing of a R290 prototype refrigerated transport system in 2017. The R290 prototype has a global warming potential (GWP) of just 3, compared to 3922 of conventional R404 systems. The main aspects that were addressed during the design of the system were circuit optimization and integration of safety measures in order to achieve the same cooling capacities as R404 systems, whilst maximizing the coefficient of performance and reducing refrigerant charge. A leak identification feature was integrated into the system, whereby a suspected leak would result in a shut-down of the system. The product was developed under the project “Emission mitigation in the transport refrigeration sector through the introduction of innovative logistics and supply structures in South Africa”. It is funded by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB), with the South African Department of Trade and Industry as the leas executing agency. …
