Is an improved ammonia water absorption cooling system. Dr. Kunze has redesigned the basic cycle ("Bypass System") and has invented the possibility for absorption heat recovery. SolarFrost is a sustainable cooling technology that offers a number of considerable advantages compared to other cooling systems:

• Operates with low input temperatures of about 80°C
• Refrigeration temperature as low as -30°C
• High energy efficiency - COP: 0.8 - 1.2
• High backcooling temperatures are possible
• No greenhouse or ozone-layer active gases
• Simplicity - no need for sophisticated regulation and control systems
• No need for electric solution pump
