Abstract
In various implementations, air conditioners may include a high pressure portion and a low pressure portion. A bypass line may divert a portion of the refrigerant from the high pressure portion to the low pressure portion to reduce the pressure of at least a part of the high pressure portion. The bypass line may be opened automatically.
Claims20
An air conditioning system comprising:
- a high pressure portion comprising a microchannel condenser;
- a low pressure portion, wherein a pressure of a refrigerant in at least a portion of the high pressure portion is greater than a pressure of refrigerant in at least a portion of the low pressure portion;
- a property sensor configured to detect a property reading, wherein the property reading is at least partially based on a property of the refrigerant in at least a portion of the high pressure portion;
- a bypass line coupling at least a part of the high pressure portion and a part of the low pressure portion, and wherein opening the bypass line reduces a pressure of at least a portion of the microchannel condenser;
- and
- a valve coupled to the bypass line, wherein the valve is adapted to open at least partially based on the pressure reading.
3 more elements
The system of claim of 1 wherein a property reading includes at least one of a temperature, a pressure, a temperature differential, or a pressure differential, a change in temperature, or a change in pressure.
A method comprising:
- determining a pressure reading at least partially based on a pressure of refrigerant in at least a portion of a high pressure portion of an air conditioner, wherein the high pressure portion comprises a microchannel condenser;
- determining if the pressure reading exceeds a predetermined maximum pressure;
- allowing a part of the refrigerant in the high pressure portion to flow to a low pressure portion of the air conditioner through a bypass line;
- allowing the pressure in at least a part of the microchannel condenser to be reduced by allowing the part of the refrigerant to flow through the bypass line.

A method comprising:
- determining a property reading of an air conditioner comprising a microchannel condenser;
- determining if the property reading exceeds a predetermined maximum property;
- allowing a part of the refrigerant in a high pressure portion of the air conditioner to flow to a low pressure portion of the air conditioner through a bypass line, if the property reading exceeds the predetermined maximum property;
- and
- allowing a pressure in at least a part of the condenser to be reduced by allowing the part of the refrigerant to flow through the bypass line.
