• a first evaporator, a first end of which is in fluid communication with the third port;
• a second evaporator, a first end of which is in fluid communication with one of the second port and the fourth port;
• a condenser, a first end of which is in fluid communication with the other of the second port and the fourth port;
• wherein a second end of the condenser, a second end of the first evaporator, and a second end of the second evaporator are in fluid communication at a first node, and a first throttling valve, a second throttling valve and a third throttling valve are respectively disposed between the condenser and the first node, between the first evaporator and the first node, as well as between the second evaporator and the first node;
