These newly developed selection charts can be practically used to select capillary tube size from the flow rate and flow condition or to determine mass flow rate directly from a given capillary tube size and flow condition. As part of general procedure, Honeywell recommends initially charging the system with 85 percent by weight of the original charge. Due to the relatively close mass flow of R448 and R22, little to no adjustment of the TXVs is expected. Capillary tube is the simplest of all devices of the account. It is normally located just ahead of the evaporator, as shown here. Di,RcmdId … For a capillary tube having an internal diameter of 1.63 mm and a length of 2.03 m, the required mass flow rate can be easily determined from this chart by knowing the condenser pressure and the degree of subcooling. 0000003393 00000 n se�eW��] �v%�Jؕ�+aW�� r��rs�v� �"�3.G��_&�M�;L�0m4)�O��O��Aү�Șz'� fAI�3ꉉ��|��F��Z�U��q�'��/��0��ApL��O��i:ɫ�}��U�&��3�o��e�i�F��ڴ��4��,�+N��-�]��w(S�#�tѡ_�� H�SB�1��_�>��~. 1042 0 obj <>stream 0000001802 00000 n The refrigerant capillary tube is a vital component to a refrigerator or air conditioner, because it condenses the amount of refrigerant supplied to the evaporator. 0000001654 00000 n We've sent your manager an email requesting an approval. 0000007581 00000 n All recommendations must be considered approximate and variations may arise in actual field applications.
