Abstract
The present invention relates to a method for testing the refrigeration capacity of a circulated water-cooled (circulated cold water is driven by a miniature water pump to radiate heat before a closet is flushed) refrigeration fan of a water tank based on the water flushing closet. The present invention is designed for the toilet use (an air conditioner with subminiature power blowing disposable cold wind to a person who uses the toilet) of a refrigeration product (not for the air conditioner for the whole room) for toilets in the patent technology of ZL02150077.0 (CN1417531A). A test facility is mainly composed of a small single heat insulated test cabinet (P), a main body device ' a cold and warm frequency conversion air conditioner ' for testing the refrigeration capacity, and the relative measuring elements. The method is mainly characterized in that the ' air conditioner ' is used for firstly making the preparatory work of refrigeration and dehumidification for an indoor environment, then, the refrigeration capacity is tested in a dry environment (an evaporator of a refrigeration product to be tested separates no condensed water in the overall process of testing), and the refrigeration capacity is mainly calculated on the basis of the heating power consumption of the ' air conditioner ' in the process of counteracting cold and heat capacity.
