A method for recovering heat (i.e., thermal) energy produced by computer hardware in blockchain (e.g., cryptocurrency) mining operations and utilizing that recovered heat energy in cooling modules. Also, a system for recovering heat energy produced by computer hardware in blockchain (e.g., cryptocurrency) mining operations and utilizing that recovered heat energy in absorption cooling modules which are an ammonia-water absorption refrigerator module and/or an absorption immersion cooling module.

A refrigerator based on a molecular sieve, including a first molecular sieve device, a second molecular sieve device, a reversing valve, and a balancing valve, wherein an air flow alternately passes through the first molecular sieve device and the second molecular sieve device through the reversing valve, and then flows back through the balancing valve, so that the first molecular sieve device and the second molecular sieve device are regenerated. The first molecular sieve device and the second molecular sieve device are capable of separating a refrigerant from a depressurized gas, and the refrigerant is condensed after reaching a certain concentration to become a liquid refrigerant, and then enters an evaporator again for refrigeration.

A temperature controller for a sorption system having an evaporator to produce a gas, a sorber containing a sorption material to sorb the gas during a sorption phase, a flow channel extending between the evaporator and sorber to provide a gas pathway connecting them, a valve to control the rate of gas flow in the flow channel, and a temperature sensor positioned to measure the temperature of an evaporator surface or the air adjacent thereto indicative of an evaporator surface temperature, and generate a temperature signal. The controller includes an inflatable member having first and second inflation states, and a control unit configured to evaluate the temperature signal and in response control the state of inflation of the inflatable member and thereby the operation of the valve to control the rate of gas flow between the evaporator and sorber through the gas pathway.

A method for recovering heat energy from computer hardware in a blockchain mining operation. The method may include the steps of providing heat energy that may be generated by computer hardware in a blockchain mining operation, and utilizing the heat energy in an absorption cooling module to generate a cooling effect with a coolant fluid. The coolant fluid may comprise a fluid refrigerant-absorbent mixture. The absorption cooling module may include an ammonia-water absorption refrigerator module, one or more heatsinks, a fluid pump, and a heat exchanger. The ammonia-water absorption refrigerator module may include a generator that may absorb heat energy adjacent to the generator. The one or more heatsinks may be positioned on the computer hardware. The fluid pump may be in fluid communication with the one or more heatsinks. The heat exchanger may be in fluid communication with the fluid pump and with the at least one heatsink.

A vacuum cooling system (10) having a first fluid (21) and a second fluid (70) circulating through the system (10) in separate cycles, said system (10) including a vacuum chamber (1) containing a portion (14) of said first fluid and a volume of gas (42) evaporated from said first fluid portion (14), a first pump means (7) for removing the gas volume (42) from the vacuum chamber (1) to create a vacuum in said vacuum chamber (1), a means for moving (8) said first fluid (21) into said vacuum chamber (1) to replenish the first fluid portion (14) in said vacuum chamber (1), and heat exchanger means (2) for cooling said second fluid (7) over which air is blown in order to cool air in a space.

A solar collection system includes an absorption refrigeration system to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.
