air-conditioner compressor judging merits: drop a few drops of water in the evaporator, a few seconds can confirm can become ice, this means that the compressor is good

turned on the power correctly, first open the cabinet door, the thermostat is counterclockwise in the off state, and then under the condition of stable open interior lighting, the thermostat clockwise to the middle position, hear the sound of the compressor starts, the cupboard door shut to observe work state.Because this is the basic judgment of the compressor, so you can know that the air-conditioner compressor whether meet the requirements. freezers thermostat discern bad
then have a thermostat, in terms of air-conditioner temperature regulation, especially according to season how to judge?First of all, the temperature of the thermostat inside the freezer to react, incase of running time is proportional to the temperature and the compressor.The thermostat is refers to the electrical signal is converted to mechanical displacement or the temperature signal, comparing with the given temperature signal, and then adjust the compressor running time.
switch ratio is the comprehensive performance of judgment of air-conditioner temperature normal operation, the longer the cooling performance conforms to the standard downtime, temperature is relatively stable, the longer the insulation performance of the air-conditioner is, the better.Through the above check, can know how to judge the temperature regulator is, so you can choose a good air-conditioner.Quality of foam layer judgment freezers
for foam layer is freezers insulation layer, can only its storage freezers and internal air-conditioner to cool.Otherwise, the cold air to escape, refrigerated food is not possible.So the stand or fall of foam layer is also very important.If we identify good foam layer, then try out by hand.A good foaming layer is hard, weight is very heavy, have preservation effect, energy efficiency is better.The snow of air-conditioner use the polyurethane foam plastic, not only high strength, high density, and the safe, efficient, and beautiful.
in addition to the above points, our air-conditioner evaporator, the evaporator is also very important parts.Its quality decides the air-conditioner cooling speed and freshness.The snow ark have completely cooling design, large evaporation area copper tube, fast cooling and fresh.
