摘要： A supersonic cooling system operates by pumping liquid. Because supersonic cooling system pumps liquid, the compression system does not require the use a condenser. Compression system utilizes a compression wave. The evaporator of compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then 'jump' or 'shock up' to the ambient pressure.
