The overproof temperature rise of the cabinet wfill directly affect safe and stable operation of the equipment, and the superheat problem is an uninterrvupted growth process. If the temperatlures of the heat points can not be found in time,or settled, the superheat extent can incessantly aggravate. And it will bave a great effect on iusulated part performance and equipment lifetime.
