Refrigerator related main parameters, electricity consumption and energy efficiency rating labeling.
Input power. Input power is too small will cause the refrigerator refrigeration compressor for a long time without shutting down, also known as the "small horse-drawn wagon", this criterion can be in the refrigerator body behind the overall factory nameplate (Haier's in the refrigerator within the freezer) or use the manual to see the 200L up and down the refrigerator as an example, try to pick the input power of more than 100W.
Compressor brand and whether it is imported. And central air conditioning, "two devices" (condenser and air conditioning evaporator) quality can directly affect the characteristics of the equipment, compressor brand is highly recommended Embraer or Zanussi. Refrigeration capacity. With commercial . Medical . Scientific research and other special must be compared, domestic refrigerators, this indicator value reference is not very useful.
Climate type. In our country according to the application of refrigerator climate environmental temperature is divided into sub-warm temperate SN, ambient temperature of 10-32 ℃, warm temperate N, ambient temperature of 16-32 ℃; Sub-tropical climate ST, ambient temperature of 18-38 ℃; Sub-tropical T, ambient temperature of 18-43 ℃. I feel or have some reference to the practical significance.
The refrigerator itself is deep. Width. High and insulation layer thickness has some correlation, but not sure. Air conditioning evaporator (in the freezer, open the chest of drawers in the shell of the rows of pipes is)
Try with a magnet, if it can be attracted to the refrigerator should be discarded immediately. Count how many of each line, the current sales market to 8 dominant, less 6, more 10 to 12, of course, the more the better, the higher the relative density, which indicates that the total area of the heat absorption reaction is large, the cooling capacity is good. At this stage of the market, many of the silk pipe, should first consider the plate tube, the total area of heat-absorbing reaction is large.
Touch how long it takes to start the air conditioner evaporator has a significant sense of ice. Condenser (some years ago are in the back wall of the refrigerator uterus, that is, the so-called "back pot", at this stage basically all embedded, the outside can not be seen first clear parts of the condenser (some in the back of the refrigerator, some in the two sides, some on one side).
Take a little bit of hand touch: a touch of how long after the boot can significantly experience hot; two touch hot is not equalized and how large the total area. The total area of the condenser is large and the temperature is high in order to have the ability to release the heat from the refrigerator. Door seal (door seal quality immediately jeopardize power consumption and cooling capacity, at this stage of the refrigerator sales market quality situation, door seal if the quality is still good can from a certain level to fill the equipment itself cooling capacity is not enough) view check ductility. Look at the door seal and shell is not close. Neat. Smooth. Can take a flashlight, open and put inside to see if it is translucent.
