1. A pump, comprising:
a first chamber containing a working fluid and providing a first space, the first space being above at least a portion of the working fluid that is within the first chamber;
an input passage coupled to the first chamber and configured to provide gas having a first temperature;
a second chamber coupled with the first chamber, the working fluid flowable between the first chamber and the second chamber via at least one first flow passage between the first chamber and the second chamber, the second chamber providing a second space, the second space being above at least a portion of the working fluid that is within the second chamber;
a first output passage coupled to the second chamber and configured to output the gas having a second temperature, the second temperature being lower than the first temperature; and
a control device coupled to the first chamber and the second chamber via one or more second flow passages, wherein the one or more second flow passages have a controllable gas flow between the first chamber and the control device or between the second chamber and the control device;
one or more second output passages coupled to the control device and configured to output a gas having a third temperature, the third temperature being higher than the first temperature;
wherein the control device comprises:
a third chamber and a fourth chamber, wherein in a first period, the gas in the fourth chamber expands and flows to the second chamber, a portion of the working fluid in the second chamber flows to the first chamber, and a portion of the gas in the first space flows to the third chamber to compress the gas in the third chamber.
