Abstract
In at least one embodiment, a vehicle climate control system including a compressor, at least one sensor, and at least one controller is provided. The compressor is configured to circulate fluid about a refrigerant loop. The at least one sensor is configured to provide a signal indicative of a pressure of the fluid in the refrigerant loop. The at least one controller is programmed to control a first valve to open to enable the fluid to flow to an evaporator for a battery responsive to the pressure of the fluid being greater than a predetermined pressure level to reduce the pressure of the fluid.
Claims18
A vehicle climate control system comprising:
- a compressor configured to circulate fluid about a refrigerant loop;
- at least one sensor configured to provide a signal indicative of a pressure of the fluid in the refrigerant loop;
- and
- at least one controller programmed to control a first valve to open to enable the fluid to flow to an evaporator for a battery responsive to the pressure of the fluid being greater than a predetermined pressure level to reduce the pressure of the fluid,
- wherein the at least one controller is further programmed to control the first valve to open to enable the fluid to flow to the evaporator for the battery responsive to the compressor being in an off state.
A method for a vehicle climate control system, the method comprising:
- circulating, via a compressor, fluid about a refrigerant loop;
- transmitting a signal indicative of a pressure of the fluid in the refrigerant loop;
- and;
- controlling a first valve to open to enable the fluid to flow to an evaporator for a battery responsive to the pressure of the fluid being greater than a predetermined pressure level to reduce the pressure of the fluid;
- and
- controlling the first valve to open to enable the fluid to flow to the evaporator for the battery responsive to the compressor being in an off state.
A vehicle climate control system comprising:
- a compressor configured to circulate refrigerant;
- at least one sensor configured to provide a signal indicative of a pressure of the refrigerant;
- and
- at least one controller programmed to control a first valve to open to enable the refrigerant to flow to an evaporator that maintains a temperature of a battery responsive to the pressure of the refrigerant being greater than a predetermined pressure level to reduce the pressure of the refrigerant, and
- wherein the at least one controller is further programmed to control the first valve to open to enable the refrigerant to flow to the evaporator responsive to the compressor being in an off state.
