The design of Danstoker’s absorption chillers is based on the need for industrial process cooling and comfort cooling in buildings.
Industrial production involves numerous production stages where electricity is currently used to cool down critical processes. However, the installation of an absorption chiller allows the industrial companies instead to utilize their waste heat to produce cooling.
As standard, the absorption chillers have an evaporator chilling effect of 50 kW to 3,500 kW. If required, combinations of several units may be designed to achieve a higher capacity.
The waste heat is used as auxiliary heat source to the chiller’s internal cycle, which offers a ratio between the total energy produced and the ”waste heat borrowed” of 0,7 to 0,8. In order to release the total energy generated by the waste heat + the process cooling, the heat pump’s hot water circuit must be connected to a cooling tower and discharged to open air.
The chilling effect of absorption chillers may be designed to achieve evaporator temperatures as low as -5 °C in a water/LiBr unit. As a result, freezing temperatures can be achieved by equipment, which is not subject to the pressure equipment directive, thereby eliminating the need for annual inspections by the supervising authorities.
