[specific embodiment]

Below in conjunction with accompanying drawing the utility model is further detailed structure of the present utility model, characteristics and purpose.

As shown in Figure 1, the aircondition of the multistage circulating heat pump of the utility model comprises compressor 11, evaporimeter 12, and refrigerant filter 13, energy-conservation valve 15, high temperature condensation loop 16 and cryogenic condensation loop 17, wherein compressor 11 comprises port one 11 and port one 12; Evaporimeter 12 includes two

cryogen interfaces

121 and 122; High temperature condenser system 16 comprises high temperature condenser 161, high temperature water pump 162, and high temperature pond 163; Wherein, high temperature condenser 161 includes the mouth of a river 1611 and delivery port 1612, described water inlet 1611 connects high temperature water pump 162, and the water inlet 1611 that the high temperature tank water is delivered to high temperature condenser 161 through water pump 162 enters condenser 161 heating and is back to 163 ponds from delivery port 162 outflows; Equally, Cryogenic condensation system 17 comprises low-temperature condenser 171, low temperature water pump 172, and low temperature pond 173; The low temperature tank water is delivered to condenser 171 heating that the water inlet 1711 of low-temperature condenser 171 enters and is flowed out from delivery port 1712 through water pump 172 and is back to 173 ponds, compares the high temperature condensation loop 16 of having connected in the present embodiment with prior art.

The complete structure annexation of present embodiment is: the port one 11 of compressor 11 interconnects by copper pipe and high temperature condensation loop 16; The port one 31 of filter 13 is connected with cryogenic condensation loop 17, and the another port 132 that filter 13 connects is connected the back by copper pipe and is connected with the port one 21 of evaporimeter 12 with choke valve 15; The another port 122 of described evaporimeter 12 is connected with the port one 12 of compressor 11, and high temperature condenser 161 and high temperature hot water pump 162 and high temperature pond 163 are connected to form high temperature condensation loop 16; In like manner, the utility model also comprises another cooling circuit, and low-temperature condenser 171 and low-temperature water heating pump 172 and low temperature pond 173 even form cryogenic condensation loop 17; Wherein, it is logical that described pond 163 and pond 173 can form current by siphunculus 18, and only need a low temperature water inlet 181 and high-temperature water outlet mouth 182, thereby realize the exchange heat in the pond.Described high temperature condensation loop 16 and cryogenic condensation loop 17 are connected in series.

Like this, the one port series connection high temperature condensation loop 16 and the cryogenic condensation loop 17 of compressor 11, the back is connected with an end of refrigerant filter 13, and refrigerant filter 13 is connected with the other end of evaporimeter 12 by choke valve 15 and compressor, thereby forms the heat pump active channel.

The cold-producing medium flow process is: compressor 11 → compressor mouth 111 → high temperature condenser 161 → (above-mentioned cold-producing medium reduces temperature after cooling off through secondary through low-temperature condenser 171, high-temperature gas becomes cryogenic liquid) → filter 13 → choke valve 15 → enter evaporimeter 12 (to enter evaporation heat-exchanger 13 after the capillary current limliting of cold-producing medium footpath, because of the space becomes the vaporization of big refrigeration Ji, the less absorption heat of pressure.) → compressor mouth 112 → get back in the compressor 11.The water route is: from running water water inlet 181 input low temperature ponds 173 → via water pump 172 and low-temperature condenser 17 circulation heating back → inflows high temperature ponds 163 through water pump 162 and high temperature condenser 16 further after the heating by delivery port 182 outflow uses.This state is that unit produces the state that hot water freezes simultaneously.

Fig. 2 is the structural representation of second embodiment of the present utility model, as shown in Figure 2, in order to make its water carry out the abundant more and saving cost of heat exchange, present embodiment high

temperature condensation loop

16 and 17 shared ponds 20, cryogenic condensation loop, described pond 20 comprise that high temperature pond 21 and low temperature pond 22 constitute UNICOM up and down.

Wherein, the part of described condenser and hot water can be divided into secondary or more than the secondary.

Adopt high temperature condensation loop 16, double loop and cryogenic condensation loop 17 further to cool off because the utility model comprises, thereby improve its refrigeration.Thereby advantage such as this equipment is practical more and durable.

The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.
