Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The heat pump of an embodiment includes a unit, an ambient temperature sensing element, and a unit control element. The unit comprises a compressor, an evaporator, a condenser, a throttling element and the like. The ambient temperature sensing element is arranged on the unit and used for sensing the current operating ambient temperature of the unit, namely the operating ambient temperature of the evaporator. The unit control element is connected with the environment temperature sensing element to acquire an environment temperature parameter, and the heating target temperature of the unit is set according to the environment temperature parameter and the unit is controlled to perform heating operation at the heating target temperature.
Specifically, in the embodiment, as shown in fig. 1, when the ambient temperature is between the first preset temperature T1 and the second preset temperature T2, the unit control element controls the unit to heat according to the first target temperature R1, and the first preset temperature T1 is lower than the second preset temperature T2. The environmental temperature is between T1 and T2, namely in a medium temperature environment, at the moment, the unit is in the optimal working environment, the exhaust pressure and the return air pressure of the compressor are both in the normal operation range, and the heating target temperature is controlled to be constant at a first target temperature R1.
When the ambient temperature is lower than the first preset temperature T1 and higher than the third preset temperature T3, the unit control element sets the heating target temperature in such a manner that the heating target temperature is gradually decreased as the ambient temperature is decreased and controls the unit to heat at the set heating target temperature. The environmental temperature is lower than T1 and higher than T3, the unit is in a low-temperature environment at the moment, the evaporation effect of a refrigerant in an evaporator is gradually deteriorated, the return air pressure of a compressor is lower, heating is performed at the low-temperature environmental temperature, the exhaust temperature required by reaching the heating target temperature set by a user is increased, the exhaust pressure of the compressor is increased, the heating target temperature is controlled to be gradually reduced along with the reduction of the environmental temperature at the moment, the exhaust temperature of the compressor can be reduced, the compression ratio during the operation of the compressor can be in the safe operation range of the compressor, and the compressor is prevented from being damaged due to the long-term operation of the unit.
In the present embodiment, gradually decreasing means gradually decreasing in a linearly decreasing manner, that is, when the ambient temperature is lower than the first preset temperature T1 and higher than the third preset temperature T3, the unit control element sets the heating target temperature in such a manner that the heating target temperature gradually decreases with the decrease of the ambient temperature, and sets the heating target temperature in such a manner that the heating target temperature linearly decreases with the decrease of the ambient temperature. It is understood that in other embodiments, the gradual decrease may also be a gradual decrease in a parabolic or other curvilinear manner or a stepwise decrease, or a corresponding combination thereof. When the temperature is gradually decreased in a linearly decreasing manner, specifically, when the ambient temperature is decreased from the first preset temperature T1 to the third preset temperature T3, the heating target temperature is controlled to be decreased from the first target temperature R1 to the second target temperature R2.
And when the ambient temperature is not higher than the third preset temperature T3, the unit control element controls the unit to heat according to the second target temperature R2. The environmental temperature is not higher than the third preset temperature T3, which indicates that the unit is in an ultra-low temperature environment, and at this time, in order to ensure the heating requirement of the customer, the higher heating target temperature is maintained as much as possible on the premise that the normal operation of the unit can be ensured, so as to meet the requirement of the customer.
When the ambient temperature is higher than the second preset temperature T2 and lower than the fourth preset temperature T4, the unit control element sets the heating target temperature in such a manner that the heating target temperature is gradually lowered as the ambient temperature is raised and controls the unit to heat at the set heating target temperature. The environmental temperature is higher than T2 and lower than T4, it is described that the unit is operated in a high-temperature environment, the evaporation effect of the refrigerant in the evaporator is better and better, if the unit is operated at the heating target temperature when maintaining the normal environmental temperature, the return air pressure of the compressor is high, part of heat generated by the unit is wasted, and all devices in the unit are in a worse operation environment. The gradual reduction described herein is similar to the control principle described above when the ambient temperature is less than T1 and greater than T3, and may be a curve type such as linear, parabolic, etc., or a gradual reduction in a stepwise manner, or a corresponding combination thereof.
When the ambient temperature is not lower than the fourth preset temperature T4, the unit control element controls the unit to heat according to the third target temperature R3, and the third target temperature R3 is lower than the first target temperature R1, so that the unit can be guaranteed to operate in a safe environment.
In this embodiment, the third target temperature R3 is not lower than the second target temperature R1, which can ensure that the unit can normally operate even in an ultra-low temperature environment, and the situation that the unit cannot continuously operate at the heating target temperature is avoided, thereby further reducing the excessive loss of the unit and prolonging the service life of the unit.
In the present embodiment, the first preset temperature T1 is preferably-30 ℃ to-20 ℃; the third preset temperature T3 is preferably-35 ℃ to-25 ℃; the second preset temperature T2 is preferably 45-55 ℃; the fourth preset temperature T4 is preferably 50-60 ℃; the first target temperature R1 is preferably 55 ℃ to 65 ℃; the second target temperature R2 is preferably 40 ℃ to 48 ℃; the third target temperature R3 is preferably 42 ℃ to 50 ℃. It is understood that, in other embodiments, the temperature may not be limited to the above, and may be determined according to the customer requirement and the unit operation condition.

Further, when the ambient temperature is lower than the first preset temperature T1 and higher than the third preset temperature T3, the heating target temperature is controlled to be linearly decreased from the first target temperature R1 to the second target temperature R2 when the ambient temperature is controlled to be decreased from the first preset temperature T1 to the third preset temperature T3 in such a manner that the heating target temperature is gradually decreased as the ambient temperature is decreased.
When the ambient temperature is higher than the second preset temperature T2 and lower than the fourth preset temperature T4, controlling the heating target temperature in such a manner that the heating target temperature is gradually decreased as the ambient temperature increases is controlling the heating target temperature in such a manner that the heating target temperature is linearly decreased as the ambient temperature increases. Further, when the ambient temperature is higher than the second preset temperature T2 and lower than the fourth preset temperature T4, the heating target temperature is controlled to be decreased from the first target temperature R1 to the third target temperature R3 when the ambient temperature is controlled to be increased from the second preset temperature T2 to the fourth preset temperature T4 in such a manner that the heating target temperature is gradually decreased as the ambient temperature is increased.
According to the heat pump and the control method of the heating target temperature of the heat pump, different heating target temperatures are set in different environment temperature intervals, so that the running condition of the unit can be adjusted according to the environment temperature, for example, the heating target temperature for the unit to run is reduced in a low-temperature environment, the compressor of the unit is enabled to run in a safe running range on the basis of ensuring the user requirement, the unit is prevented from continuously running for a long time, the unit loss is reduced, and the service life of the unit is prolonged; the heating target temperature of the unit operation is reduced under the high-temperature environment, the heat in the high-temperature environment can be fully utilized, the waste of the unit heating energy is reduced, the protection of the unit is facilitated on the premise of ensuring the normal operation of the unit under the high-temperature environment, and the occurrence rate of faults is reduced.
