WATER PURIFIER, METHOD OF PURIFYING WATER, FLUID PURIFIER AND METHOD OF PURIFYING A FLUID

摘要

A water purifier includes a first crystallization chamber and a second crystallization chamber that each receives a supply of input water; wherein each of the first and second crystallization chambers is a freeze/thaw chamber in which water is alternately frozen and thawed. A refrigerant circuit alternately supplies cold refrigerant to freeze the input water in one of the crystallization chambers, and supplies heated refrigerant to the other of the crystallization chambers to thaw the purified water. The first and second crystallization chambers operate concurrently and out-of-phase whereby heat recovered from freezing in one of the crystallization chambers is transferred by the refrigerant circuit for use in thawing in the other of the crystallization chambers. The refrigerant circuit includes a desuperheater that at least partially condenses heated refrigerant such that waste heat of compression generated by the desuperheater is rejected into wastewater via contraflow heat exchange with the heated refrigerant.
