Abstract
The utility model discloses a kind of heat pump cooling system, it includes PLC, water tank, first water pump and the second water pump, water tank is built with anti-icing fluid, first, second water pump is connected by water inlet pipe and return pipe with water tank respectively, the backwater tube portion being connected with the first water pump is wound in heat pump oil supply system, the return pipe being connected with the second water pump passes through a blower fan, return pipe in blower fan is more than the caliber of other parts in the return pipe for the caliber of helix tube and helix tube, first water pump is in normally open under PLC control, PLC is set with the setting value of anti-icing fluid temperature, when the temperature of the anti-icing fluid in water tank is higher than setting value, second water pump and blower fan start with to cooling down anti-icing fluid simultaneously under PLC control.Anti-icing fluid is circulated between water tank and heat pump oil supply system by the first water pump, can rapidly realize cooling in time；Second water pump can cool down to the anti-icing fluid in water tank, avoid anti-icing fluid temperature too high.
Description
Technical field
A kind of heat pump is the utility model is related to, especially a kind of heat pump cooling system.
Background technology
Oil supply system has the device of cooling in itself in existing heat pump, but due to the limitation of itself, oil supply system sheet
The cooling device of body can not be timely quickly heat pump oil supply system cooling down, in order to solve the problems, such as cooling, it is necessary to set
One external device (ED) to carry out supplement heat rejecter to heat pump oil supply system.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of heat pump cooling system of good cooling results.
In order to solve the above-mentioned technical problem, the utility model includes PLC, water tank, the first water pump and the second water pump, the water
Case is connected by water inlet pipe and return pipe with water tank respectively built with anti-icing fluid, first water pump and the second water pump, and described
The backwater tube portion of first water pump connection is wound on to be cooled down to heat pump oil supply system in heat pump oil supply system, with described second
The return pipe of water pump connection passes through a blower fan, and the blower fan is placed in outdoor and is used to cool down the anti-icing fluid in return pipe,
Return pipe in the blower fan is more than the caliber of other parts in the return pipe for the caliber of helix tube and helix tube, and described first
Water pump is in normally open under PLC control, and the PLC is set with a setting value to the temperature of the anti-icing fluid in water tank,
When the temperature of the anti-icing fluid in water tank is higher than setting value, the second water pump and blower fan start with to water simultaneously under PLC control
Anti-icing fluid in case is cooled down.
The beneficial effects of the utility model are：The utility model is by the first water pump by anti-icing fluid in water tank and heat pump fuel feeding
Circulated between system, provide an outside cooling device for heat pump oil supply system, can be rapidly heat pump fuel feeding system in time
System cooling down；In addition, when the temperature of the anti-icing fluid in water tank is higher than setting value, the control of the second water pump and blower fan in PLC
It is lower to start simultaneously, the anti-icing fluid in water tank can be cooled down, avoid anti-icing fluid temperature too high, to cause heat pump oil supply system
Cooling effect it is more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model heat pump cooling system.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Referring to Fig. 1, heat pump cooling system of the present utility model includes PLC, water tank 1, the first water pump 2 and the second water pump 3.
The water tank 1 is built with anti-icing fluid, the good cooling results of anti-icing fluid.
The water pump 3 of first water pump 2 and second is connected by water inlet pipe and return pipe with water tank 1 respectively.In the first water pump 2
In the presence of the second water pump 3, anti-icing fluid can circulate in water tank 1.
The backwater tube portion being connected with first water pump 2 is wound in heat pump oil supply system 4 to enter to heat pump oil supply system 4
Row cooling, the first water pump 2 circulate anti-icing fluid between water tank 1 and heat pump oil supply system 4, and one is provided for heat pump oil supply system
Individual outside cooling device.First water pump 2 is in normally open under PLC control, as long as heat pump is in the operating condition, the
One water pump 2 is under starting state, is always the cooling down of heat pump oil supply system 4.
The return pipe being connected with second water pump 3 passes through a blower fan 5, and the blower fan 5 is placed in outdoor and is used for backwater
Anti-icing fluid in pipe is cooled down.Return pipe in the blower fan 5 is more than the return pipe for the caliber of helix tube 6 and helix tube 6
The caliber of middle other parts, it to be rapidly the anti-icing fluid cooling in it that blower fan 5 is easy in the design of helix tube 6.Described PLC pairs
The temperature of anti-icing fluid in water tank 1 is set with a setting value, and setting value is 23 DEG C.When the temperature of the anti-icing fluid in water tank 1 is high
When setting value, the second water pump and blower fan start simultaneously under PLC control, and the anti-icing fluid in water tank can be cooled down,
Avoid anti-icing fluid temperature too high, to cause the cooling effect of heat pump oil supply system more preferable；When the temperature of the anti-icing fluid in water tank 1
When degree is returned to below setting value or setting value, the second water pump and blower fan are closed under PLC control.
In summary, content of the present utility model is not limited in the above embodiments, and those skilled in the art can
To propose other embodiments within technological guidance's thought of the present utility model, but these embodiments are included in this practicality newly
Within the scope of type.
