It is refrigerant after once damming, sandwich passage (20) entrance (21) and the joint III (14) on housing (3) in passage (20)
It is connected, sandwich passage (20) outlet (22) is internal in housing (3)；
Described pipe I (16) is the efficient heat-exchanging pipe of common tube, bellows, inner helix pipe or outer spiral tube form.
Described economizer (7) is the plate type heat exchanger being laminated by annular or fan-shaped sheet metal.
The plate type heat exchanger has two passages, passage I and passage II, freezes in the passage I for main loop
Agent, both ends are connected with housing (3) top connection I (8) and joint II (13) respectively, are to freeze after once damming in the passage II
Agent, described one end of passage II are connected with the joint III (14) on housing (3), and it is internal that the other end is opened on housing (3).
It is an advantage of the invention that：
1st, the economizer is located inside compressor, is not take up system space completely, solves prior art economizer and independently accounts for
The problem of with space；
2nd, the economizer is located inside compressor, and economizer inside and outside differential pressure is small, and the smaller pipe of thickness can be selected, reduce cost
On the basis of, heat exchange efficiency is improved, cost is low compared with prior art, and heat exchange efficiency is high；
3rd, the economic gas inner refrigerant inherently will strong with the compressor inner refrigerant of room I exchanged heat, therefore nothing
Any Insulation need to be taken economizer, solves the heat-insulated process problem of prior art heat exchanger.
