Compared with the existing technology, the present invention has the positive effect that: (1) the delivery temperature control of the invention according to compressor Distributive value processed, when delivery temperature is higher, pressure chamber pressure rise, mandrel is moved down, first through hole, the second through-hole and third through-hole The upper access circulation constituted increases, and increases distributive value, achievees the purpose that fast cooling;When delivery temperature reduction, pressure chamber Pressure reduction, mandrel move up under the action of the spring, and upper access circulation is reduced, and save distributive value;(2) increasing the cold bypass of oil In technical solution, when delivery temperature is higher, pressure chamber pressure rise, mandrel is moved down, and first through hole, the second through-hole and third are logical The upper access circulation that hole is constituted increases, meanwhile, the underpass circulation that fourth hole, fifth hole and the 6th through-hole are constituted Amount is reduced, to reach in the oil of upper access, the room temperature oil ratio from the cold bypass of oil is reduced, the low-temperature oil from oil cooler Ratio improves, and also reduces the temperature of oil spout while increasing distributive value, further improves cooling effect;Work as delivery temperature It reduces, pressure chamber pressure reduction, mandrel moves up under the action of the spring, and upper access circulation is reduced, and underpass circulation increases, no Distributive value is only saved, and improves the bulk temperature of oil spout, it is ensured that oil temperature will not be too low, reduces the wind of refrigerant condensation Danger.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
The technical solution that the invention will now be described in detail with reference to the accompanying drawings:
Such as Fig. 1, a kind of compressor row temperature control device further includes including the temperature sensing package 1 being mounted on compressor exhaust pipe Connecting pipe 2, oil cooler 4 and regulating mechanism 3.
The regulating mechanism 3 includes columnar ontology, and the bodies top is equipped with pressure chamber 3-1, is at the top of pressure chamber 3-1 Flexible sheet;Also vertically-mounted in the ontology to have mandrel 3-2, the upper end the mandrel 3-2 is located in pressure chamber 3-1, thus It is moved down under the action of pressure along chamber body in pressure chamber 3-1, the lower end mandrel 3-2 is connected by spring 3-4 with ontology.
The adjusting rod 3-5, the adjusting rod 3-5 for adjustment spring 3-4 initial compression amount are also equipped in the ontology Upper end holds the bottom the spring 3-4, and lower end is arranged in the through-hole of body bottom portion, which passes through thread fiting mode Knob is installed, knob inner end is in contact with the lower end adjusting rod 3-5, the height of adjusting rod 3-5 is adjusted by rotating the knob, Achieve the purpose that change spring 3-4 initial compression amount.
It is horizontal on the chamber body side wall to offer coaxial first through hole and the second through-hole, water on the mandrel 3-2 It is opened flat and is equipped with third through-hole, the third through-hole communicates between first through hole and the second through-hole and with the two, and axis is located at The top of the two axis;First through hole, the second through-hole and third through-hole constitute upper access.
It is connected on the outside of the first through hole for the injection line to compressor oil spout;
The temperature sensing package 1 is connected by connecting pipe 2 with the pressure chamber 3-1, and the temperature sensing package 1 is provided with temperature liter The high and temperature sensing medium of volume expansion;Specifically, the temperature sensing medium be Binary Refrigerant Mixtures, the component of mix refrigerant and Mass ratio is R245fa:R125=0.6:0.4.
The oil cooler 4 has oil inlet and oil outlet, and the oil outlet is connected with second through-hole.Oil inlet For being passed through room temperature oil.
When delivery temperature is higher, pressure chamber 3-1 pressure rise, mandrel 3-2 is moved down, and upper access circulation increases, and increases spray Oil mass achievees the purpose that fast cooling;When delivery temperature reduces, pressure chamber 3-1 pressure reduction, mandrel 3-2 is acted in spring 3-4 Under move up, upper access circulation is reduced, and saves distributive value.
Further, horizontal on the chamber body side wall to offer coaxial fourth hole and fifth hole, described the Four through-holes and fifth hole are located at the lower section of first through hole and the second through-hole, and level offers the 6th through-hole on the mandrel 3-2, The lower section of both 6th through-hole communicates between fourth hole and fifth hole and with the two, and axis is located at axis;The Four through-holes, fifth hole and the 6th through-hole constitute underpass.
