air-conditioner includes the capillary tubes type and expansion valve type. But only capillary tubes
applied in the home use air-conditioner because of the small flux it is. The following is the detailed
introduction for it.

1mm—2mm, and the length is 500mm—1000mm. With the properties of simple structure, easy
machining, low cost and reliability, especially enough capability for the throttling need at a stable
indoor room temperature; it’s popularly applied in the practice. However, it has a weak
accommodating function, which can be workable under a rating working status but can’t adjust the
flux following with the variety of the load of the refrigeration system.

between the condenser and the evaporator for the function of reducing pressure and throttling flux. It
can prevent the liquefied refrigerant at a normal temperature and pressure of the condenser entering
into the evaporator directly so as to reduce the pressure of the evaporator in favor of the evaporation
of the refrigerant. After stopping the operation of the compressor, it can maintain a balance between
the low-pressure part and the high-pressure part for the convenient re-start of the compressor. The
resistance will be reduced and the flux of the refrigerant will be increased if enlarging the inner
diameter or shortening the length of the capillary tubes, and on the contrary if otherwise. The capillary
tubes must match the refrigerating devices and cannot be replaced freely, especially when the inner
diameter, the roughness of the inner surface and the length are in difference, it may affect the normal
operation of the refrigeration system badly. As the narrowest part of the refrigeration system, the
capillary tubes may easily to be jammed. The figuration of the capillary tubes is indicated in the
picture 2-6 as the below.

nozzle. The refrigerant enters inside through the nozzle and to be guided in different ways following
the inner surface of the cone. There are many equally distributed holes at the bottom of the cone,
which are connected to the various accesses of the evaporator through the capillary tubes. When the
refrigerant flows through the nozzle of the throttling liquid distributor, its flow speed will be
accelerated due to the sudden contraction to the section area of the stream, and force the liquid and gas
mix together equally to flow into the capillary tubes which connect to the throttling ring. Consequently,
the flows will enter inside the various tubes of the evaporator so as to enhance the evaporating
efficiency for the evaporator. Refer to the below picture 2-7 of the figure of liquor separator.
