Further, a liquid storage device and a throttling assembly are arranged between the condenser and the evaporator.
Further, a filter is arranged between the liquid storage device and the condenser.
Further, the air conditioner also comprises a condensing fan, and the condensing fan is used for air cooling towards the evaporator.
Further, the condenser is a plate heat exchanger.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model discloses an independent airtight circulation can not cause any rotten and pollution to fluid, and for electric heating pipe heating, the energy-conservation nature is obvious moreover, the utility model discloses a whole circulation system operation is reliable, and the too high oil temperature can also refrigerate fluid.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals:
the system comprises a compressor 1, a condenser 2, an evaporator 3, an oil pump 4, a liquid storage device 5, a throttling assembly 6 and a condensing fan 7.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description.

Referring to fig. 1, a heat pump type oil heating unit includes a compressor 1, a condenser 2, an evaporator 3, and an oil pump 4, the compressor 1, the condenser 2, and the evaporator 3 are connected in series by a pipeline and form a circulation, the oil pump 4 pumps cold oil into the condenser 2 and discharges the cold oil in a hot oil manner, two independent closed passages are provided in the condenser, one of the closed passages is connected with the compressor and the evaporator, and the other closed passage is connected with the oil pump.
In this embodiment, a liquid storage device 5 and a throttling component 6 are arranged between the condenser 2 and the evaporator 3, so that the returned refrigerant liquid can be conveniently controlled.
In this embodiment, a filter (not shown) is provided between the accumulator 5 and the condenser 2. The refrigerant liquid can be filtered by arranging the filter, and the adverse effect of impurities on the evaporator is avoided
In this embodiment, the refrigeration system further comprises a condensing fan 7, wherein the condensing fan 7 is used for air cooling the evaporator 3, so that the refrigeration effect of the evaporator 3 is accelerated.
In this embodiment, the condenser 2 is a plate heat exchanger. The high-performance brazed plate heat exchanger is preferably adopted to enable two fluids to run in independent closed channels, and no pollution is caused to oil.
The utility model discloses also can heat combustible fluid such as aviation kerosene, petrol.
The utility model discloses a theory of operation:
the compressor 1 sucks low-temperature low-pressure refrigerant gas, discharges high-temperature high-pressure refrigerant gas (above 65 ℃) and enters the condenser 2 (plate heat exchanger), the high-temperature high-pressure refrigerant gas is changed into high-temperature high-pressure refrigerant liquid in the condenser 2, the refrigerant is changed into phase (gas is changed into liquid) to release heat, cold oil is heated and enters the condenser through the oil pump to absorb heat to form cold oil to be discharged, the high-temperature high-pressure refrigerant liquid is changed into low-temperature low-pressure liquid through the throttling component 6, the low-temperature low-pressure refrigerant liquid enters the evaporator 3 (fin heat exchanger), the low-temperature low-pressure refrigerant liquid is changed into low-temperature low-pressure refrigerant gas in the evaporator, the refrigerant is changed into phase (liquid is changed into gas) to absorb heat (is absorbed from air), the low-, and heating the cold oil.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
