Capillary calculation method:
Refrigeration system is generally called about 0.5 ~ 2mm inner diameter, the length of about 1 ~ 4m purple steel tube for capillary. After the inner diameter and length have been determined, the flow rate of the capillary is mainly affected by the pressure difference between the inlet and outlet, that is, the pressure difference between the high and low pressure ends. It is also related to the degree of undercooling of the incoming liquid, the amount of gas containing flash, the degree of tube bending and the number of coils.
Therefore, when the unit system is fixed, it can not arbitrarily change the working condition or replace any specification of capillary. According to relevant experiments, under the same working conditions and the same flow conditions, the capillary length is approximately proportional to the 4.6 power of its inner diameter, that is, L1/L2=(d1/d2)4.6.
When the ambient temperature rises or the amount of refrigerant is too much, the condenser pressure increases, and the increase of capillary flow increases the evaporator pressure and evaporation temperature. On the contrary, when the ambient temperature is reduced or the refrigerant charging amount is insufficient, the condenser pressure is low, and the capillary flow is reduced, which will reduce the evaporator pressure and evaporation temperature, leading to the reduction of cooling capacity, or even less than the required temperature.
Therefore, the refrigerant charge must be strictly controlled according to the design requirements of the refrigeration equipment using capillary tube. For example, the refrigerator of 200L or so adds R12 in 150 grams or so, and the deviation is not more than 5 grams. The initial liquid filling amount of the general system, M, can be approximately determined by the following formula: M=20+0.6V (g) in the formula: V evaporation coil volume (CM3)
The copper capillary tube with an inner diameter of 0.5mm and a length of 3m is used in general refrigerators.
Copper capillary tube with inner diameter of 1.42mm and length of 450mm is used in general air conditioning.
