The current energy management system runs largely on fossil fuels. Around the world awareness starts to emerge that energy can be used more efficiently and more renewable energy sources should be used. The use of waste heat is an ultimate tool for energy efficiency.

In order to meet the growing demand for cooling and aspire to further reduce the use of fossil fuels, it is the SolabCool system that can cool by using heat. By applying the SolabCool system, it is also possible to utilize heat in the summer, and increasing the (economic) efficiency of (for example) district heating.

The required heat on which the system works comes from heat networks, solar energy, or combined heat and power.

SolabCool technology

The principle of the technology is based on SolabCool "solid sorption". By taking advantage of the hygroscopic properties of the solid matter (solid) a liquid can be absorbed (sorption), also known as adsorption. This takes place in the heart of the SolabCool, the thermo-chemical heat pump. The thermo-chemical heat pump consists of two cylindrical chambers. In each room there is a reactor, a condenser and an evaporator. In order to provide cooling a process of charging and discharging is required.

Charging process

In the beginning of the process, the SolabPump contains silica gel saturated with water. In the charging process, thermal energy is used to desorb (blue arrow) the water from the silica gel. The condenser operates at a reduced temperature which results in a lower vapor pressure at the accumulator. This causes the generated steam to flow to the condenser where it condenses. The condensation heat is transferred to a heat discharge cooler by means of a separate hydraulic cooling system (red arrow). The SolabPump is charged when the silica gel is dry and the water is fully condensed.

Discharge process

After the charging process, the SolabPump contains dry silica gel, with a very low water content. In the discharge process, the temperature in the accumulator is reduced resulting in a lower vapor pressure at the accumulator. As a result of the low pressure in the accumulator, the water evaporates out of the condenser / evaporator and extracts heat. The extracted heat is supplied by means of a separate internal cooling circuit (blue arrow). Due to this transfer of heat an area can be cooled. The adsorption heat produced in the process is transferred to the heat cooler (red arrow). The SolabPump is discharged when the silica gel is saturated with water. Temperatures will then return to their original values. From this point, the process can start again. Because the SolabPump can function with heat of relatively low temperatures (60-95 ° C), it is possible to obtain cost efficient cooling.
