Product Description:
1, What is a microchannel condenser
A microchannel condenser is a heat exchanger in a refrigeration
system, characterized by the use of microchannels made of metal
plates to achieve fluid flow and heat transfer. Microchannel
condensers are widely used in fields such as household air
conditioners, automotive air conditioners, and commercial
refrigerators due to their high efficiency, portability, small
footprint, and low cost.
2, The refrigeration system principle of microchannel condenser
The refrigeration system of a microchannel condenser consists of
four main parts: a compressor, a condenser, an expansion valve, and
an evaporator. During the refrigeration process, when the
refrigerant comes out of the compressor, it enters the microchannel
condenser first. In the condenser, the refrigerant releases heat
due to contact with ambient air and becomes liquid, which is then
converted into a low-pressure liquid refrigerant through an
expansion valve and enters the evaporator. In the evaporator, the
refrigerant will absorb heat from the air and evaporate into a
gaseous state. After the refrigerant enters the compressor again,
the cycle is restarted.
Features:
Unlike capillary refrigeration systems, microchannel condensers do
not require capillaries to control the flow of refrigerant. In a
capillary refrigeration system, due to the damping effect of the
capillary, the refrigerant can only flow slowly within the
capillary, controlling the flow rate and pressure of the
refrigerant. Due to the small flow resistance of the liquid
refrigerant in the microchannel of the microchannel condenser, the
liquid refrigerant can freely flow in the microchannel, thereby
achieving control of refrigerant flow and pressure.
The refrigeration system of microchannel condensers does not
require capillaries to control the flow of refrigerant, as the
liquid refrigerant flow resistance in the microchannels of
microchannel condensers is relatively small. Microchannel
condensers have the advantages of high efficiency, portability,
small footprint, and low cost, and are widely used in fields such
as household air conditioners, automotive air conditioners, and
commercial refrigerators.
