Abstract
A tube shell ice-maker has a false bottom compartment in which trapped refrigerant gas is present to prevent ice formation around the bottom during ice-making and from which during defrosting hot gaseous refrigerant flows upwardly into the refrigerant within the tubes, the liquid remaining within the tubes, whereby delay in initiating further ice-making is minimized.
