Based on the defrosting principles of frost-free refrigerator-freezers evaporator, this paper presented improved design scheme of defrosting system, including aluminum tube conducting defroster being converted into quartz tube radiating defroster and removing thermostat holddown groove.

Based on the characteristic analysis of isobutane refrigerant,this paper explains the technical difficulties and the based standards for isobutane refrigerant used in no frost refrigerators.

Research of PM-2010 Foaming Behavior in Cyclo-iso-pentane System for Refrigerator;

The scrubbing machine used for compressor cylinder of the refrigerator;

Research and Test on Noise Reduction of a Refrigerator;

According to a problem of noise in reciprocating refrigerators compressor,the mechanism of noise in compressor and the transmission path has been introduced,and the method of noise control in reciprocating refrigerator compressor currently has been summarized.

This paper discusses the present situation of the energy saving tech- nology of the refrigerators.

A Haier HRF-285 two-circuit cycle refrigerator/freezer with parallel evaporators based on the temperature and time-sharing running control strategy was tested.

Based on the analysis that the transient characteristics of condenser and evaporator have little influence on dynamic performance of refrigerator/freezer,a quasi-dynamic model of refrigerator/freezer simulation was developed, in which steady models are developed for condenser and evaporator.
