Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In attached drawing
Give presently preferred embodiments of the present invention.But the present invention can realize in many different forms, however it is not limited to this paper institutes
The embodiment of description.On the contrary, the purpose for providing these embodiments is to make the understanding to the disclosure more thorough
Comprehensively.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The normally understood implication of technical staff is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein "and/or" includes one or more phases
The arbitrary and all combination of the Listed Items of pass.
The heat pump of one embodiment includes unit, environment temperature sensing element and unit allocation element.Unit include compressor,
The components such as evaporator, condenser and restricting element.Environment temperature sensing element is located on unit currently to be run for sensing unit
Environment temperature, i.e., evaporator operation environment temperature.Unit allocation element is connected with environment temperature sensing element to obtain ring
Border temperature parameter, according to the heating target temperature of environment temperature parameter setting unit and control unit with the heating target temperature into
Row heating operation.
As shown in Figure 1, specifically, in the present embodiment, preset when environment temperature is located at the first preset temperature T1 and second
When between temperature T2, unit allocation element controls unit to be heated according to first object temperature R1, and the first preset temperature T1 is less than the
Two preset temperature T2.Environment temperature is between T1 and T2, i.e., in medium temperature environment, unit is in best effort ring at this time
Border, the pressure at expulsion and back pressure value of compressor are in normal operation range, and control heating target temperature is in the first mesh
It is constant to mark temperature R1.
When environment temperature is less than the first preset temperature T1 and when being higher than the 3rd preset temperature T3, unit allocation element according to
The reduction of environment temperature, the mode that heating target temperature gradually reduces sets heating target temperature and controls unit according to setting
Heating target temperature heating.Environment temperature is less than T1 and is higher than T3, and unit is in low temperature environment at this time, and refrigerant is in evaporator
Middle evaporation effect is gradually deteriorated, and the back pressure of compressor is relatively low, and the heating at a temperature of low temperature environment is, it is necessary to reach user's setting
The required delivery temperature of heating target temperature will raise, the pressure at expulsion of compressor raise, at this time control heat target
Temperature is gradually reduced with the reduction of environment temperature, can reduce the delivery temperature of compressor, makes compression during compressor operating
Than that can prevent unit longtime running from causing compressor damage in compressor operational envelope.
In the present embodiment, gradually reduce and refer to gradually reduce in a manner of linear reduction, namely when environment temperature is less than
First preset temperature T1 and when being higher than the 3rd preset temperature T3, unit allocation element is according to the reduction with environment temperature, heating
The mode that target temperature gradually reduces set heating target temperature be according to the reduction with environment temperature, heating target temperature with
The mode of linear reduction sets heating target temperature.It is understood that in other embodiments, it can also be with parabola gradually to reduce
The mode reduced etc. curvilinear style or staged gradually reduces, or corresponding combination.When being gradual in the mode of linear reduction
During reduction, be specifically environment temperature from the first preset temperature T1 be reduced to the 3rd preset temperature T3 when, control heating target temperature

When environment temperature is not higher than the 3rd preset temperature T3, unit allocation element controls unit according to the second target temperature
R2 is heated.Environment temperature is not higher than the 3rd preset temperature T3, illustrates that unit is in ultra-low temperature surroundings, at this time, in order to ensure visitor
The heating demands at family, are ensureing that unit can keep higher heating target temperature as far as possible on the premise of normal operation, to meet
The demand of client.
When environment temperature is higher than the second preset temperature T2 and when being less than the 4th preset temperature T4, unit allocation element according to
The rise of environment temperature, the mode that heating target temperature gradually reduces sets heating target temperature and controls unit according to setting
Heating target temperature heating.Environment temperature is higher than T2 and is less than T4, illustrates that unit is under hot environment and runs, at this time refrigerant
Evaporation effect in evaporator is become better and better, if unit maintains heating target temperature during Normal Environmental Temperature to run, it will
Make the back pressure of compressor high, the partial heat of unit generation is wasted, also so that each device is in worse in unit
Running environment, the exhaust temperature of compressor can be reduced by controlling heating target temperature to be raised with environment temperature gradually to reduce
Degree, enables compression ratio during compressor operating in compressor operational envelope, the miscellaneous part of unit is in safer
In the environment of run.Control principle is similar when gradual reduction described herein is less than T1 with above-mentioned environment temperature and is more than T3, can
Gradually reduced in a manner of being the curvilinear style such as linear, parabola or staged reduction, or corresponding combination etc..
When environment temperature is not less than the 4th preset temperature T4, unit allocation element controls unit according to the 3rd target temperature
R3 is heated, and the 3rd target temperature R3 is less than first object temperature R1, can ensure to transport in the case where unit is in the environment of safety at this time
OK.
In the present embodiment, the 3rd target temperature R3 is not less than the second target temperature R1, it is ensured that unit is in ultralow temperature
Under environment also can normal operation, will not there is a situation where do not reach heating target temperature continuous service, further reduce unit
Excessive loss, extend the service life of unit.
In the present embodiment, preferably -30 DEG C~-20 DEG C of the first preset temperature T1；Preferably -35 DEG C of 3rd preset temperature T3
~-25 DEG C；Preferably 45 DEG C~55 DEG C of second preset temperature T2；Preferably 50 DEG C~60 DEG C of 4th preset temperature T4；First object temperature
