Embodiment
For the objects, technical solutions and advantages of the present invention are more clearly understood, develop simultaneously embodiment referring to the drawings, right
The present invention is further described.
It is the structural representation of the present invention described in Fig. 1.A kind of multi-freezing pipe air conditioning devaporizer（2）, including heat exchange
Device（1）, cooler（2）, cooling medium, cooling medium pipeline（7）, refrigerant, refrigerant tubing（8）, indoor set（5）, refrigeration
Machine（6）.The cooler（2）Input pass through refrigerant tubing（8）With heat exchanger（1）Delivery outlet a is connected, and output end passes through
Refrigerant tubing（8）With heat exchanger（1）Input port b is connected；The indoor set（5）Output end pass through cooling medium pipeline（7）
With heat exchanger（1）Input port f be connected, input and heat exchanger（1）Delivery outlet e be connected；The refrigeration machine（6）Input
Pass through refrigerant tubing（8）With heat exchanger（1）Delivery outlet c be connected, output end and state heat exchanger（1）Input port d be connected；Institute
Cooling medium is stated in cooling medium pipeline（7）Interior circulation；The refrigerant is in refrigerant tubing（8）Interior circulation.
When outdoor environment temperature is higher, cooler（2）Interior temperature and pressure is also higher, heat exchanger（1）Interior high temperature or
Gaseous refrigerant is transported to refrigeration machine by machine power（6）, system operation mechanical refrigeration pattern, as shown in Figure 2.Indoor set
（5）In cooling medium from indoor absorption heat, the cooling medium after heating enters heat exchanger（1）Indoor set is returned to after cooling
（5）Circulated next time.Heat exchanger（1）The cooling medium heat exchange of middle low temperature or liquid refrigerant and high temperature, the height after heating
