Defrost recycle device

An apparatus for use with a temperature control device for indicating an occurrence of a premature termination of a defrost operation, said temperature control device being configured to control temperature within an enclosed space, said temperature control device generating a termination indication when said defrost operation terminates, the apparatus comprising:

• a sensing means operatively connected with said temperature control device for sensing said termination indication;
• a monitoring means operatively connected with said sensing means for monitoring a parameter associated with a condition within said enclosed space as a first measured parameter, and for monitoring elapsed time from said termination indication as a second measured parameter;
• a first comparing means operatively connected with said monitoring means for comparing a selected parameter of said first measured parameter or said second measured parameter with a first predetermined value;
• a second comparing means operatively connected with said first comparing means and said monitoring means, for comparing the other parameter of said first measured parameter or said second measured parameter than said selected parameter with a second predetermined value when said selected parameter substantially equals said first predetermined value;
• and
• a signal generating means operatively connected with said second comparing means for generating a premature termination signal when said other parameter has a particular relationship with said second predetermined value.

A method for indicating an occurrence of a premature termination of a defrost operation, said defrost operation being performed by a defrost control device, said defrost control device generating a termination indication when said defrost operation terminates, the method comprising the steps of:

• sensing said termination indication;
• measuring one of a first parameter and a second parameter associated with said defrost operation as a first measured parameter;
• measuring the other of said first parameter and said second parameter than said first measured parameter as a second measured parameter;
• generating a second measured parameter value indicating said second measured parameter as measured substantially when said first measured parameter substantially equals a first predetermined value;
• comparing said second measured parameter value with a second predetermined value;
• and
• generating a premature termination signal when said second measured parameter value has a particular relationship with said second predetermined value.
