All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The press frequency control method, device, equipment and medium of the heat pump system provided by the embodiment of the application are described in detail below by specific embodiments and application scenes thereof with reference to the accompanying drawings.
A heat pump is a device for regulating the temperature in a room, and is generally composed of a water tank, a double pipe heat exchanger, a condenser, an expansion valve, a press, an evaporator, and the like. The condenser is usually arranged inside the double-pipe heat exchanger to heat the water of the double-pipe heat exchanger, the hot water prepared by the double-pipe heat exchanger exchanges heat with the water of the water tank to heat the water of the water tank, a user can connect the water tank with the ventilation disc and the floor heating module to heat air, and the water tank is communicated with a bathroom or a kitchen to obtain hot water. When refrigeration is needed, the condenser inside the double-pipe heat exchanger bears the function of an evaporator, cold water is prepared through heat exchange of a refrigerant, and a user can cool air by connecting the water tank with the ventilation disc and the floor heating module. During the heat pump heating process, the condenser absorbs heat in the indoor air and converts the heat into heat energy of the refrigerant. The refrigerant emits the heat energy in the flowing process, and returns to the condenser through the expansion valve to absorb the heat in the indoor air again. In this way, the condenser continuously absorbs and emits heat to generate hot water.
Taking the existing heat pump heating as an example, the operation frequency of the heat pump system press depends on the water temperature required by the user and/or the hot water quantity required by the user, so when the water temperature required by the user is high and/or the hot water quantity required by the user is large, for example, the hot water required by the user is high at night and/or the water consumption required by the required quantity is large, the existing scheme is to adjust the press frequency of the heat pump unit according to the required temperature and/or the required quantity, and the press frequency is always preset according to working conditions, for example, when the required temperature is located in a certain interval, the press executes a certain preset frequency and the like. In the prior art, the press operation mode is neither an energy efficiency optimal mode nor a capacity optimal mode, and is only a normal operation mode based on safe operation, namely the energy efficiency is not maximum, and the capacity is not optimal.
Based on the technical problems existing in the prior art, the following scheme is provided.
Example 1
Fig. 1 is a flow chart of a press frequency control method of a heat pump system according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:
s101, acquiring an operation mode of the press, and determining an adjustment mode of the press frequency according to the operation mode.
First, the execution scenario of the present solution may be a scenario of adjusting the heat pump system. Specifically, when a user needs to use a large amount of hot water in a short time, the heat pump system can be set to be in the capacity optimal mode, hot water can be provided faster than the original natural frequency mode, and when the user does not need a large amount of hot water, the heat pump system can be set to be in the energy efficiency optimal mode for saving electric energy, and energy consumption can be saved more than the original natural frequency mode.
Based on the above usage scenario, it can be understood that the execution subject of the present application may be the control system of the heat pump system, or may be a program running on a computer. And are not limited in this regard.
In this solution, the operating mode may be a mode of adjusting the press frequency. Specifically, the frequency of the press is regulated through the circuit board, so that the effect of saving electricity or intensively producing more hot water in a short time is achieved. And press frequency refers to the number of times it is run over a period of time. In general, the higher the press frequency, the greater the indoor temperature difference, and the better the cooling or heating effect of the heat pump. The different press frequencies are not necessarily the same and may vary. Typically, the press frequency of a domestic heat pump system is between 50 and 60 Hz. The press frequency is also related to the temperature in the chamber. If the temperature in the chamber is high, the press frequency may decrease; if the temperature in the chamber is low, the frequency of the press may increase. The method for adjusting the press frequency is determined by the mode of operation selected by the user. Specifically, the adjustment can be completed by changing the frequency of the press to raise or lower the frequency to a certain value.
S102, after the heat pump system is operated for a preset time period, working parameters of the press are obtained.
In the scheme, after the heat pump system needs to run for a preset time, the working parameters of the press are acquired. Specifically, the preset duration may be a preset time, and the heat pump system needs a certain time to reach the frequency stability after being started, and at this time, the press frequency of the heat pump system is adjusted again. The operating parameter of the press may be an operating parameter of the press. In particular, the compression frequency of the heat pump press is affected by operating parameters, which may include the discharge temperature and the press current. The discharge temperature may be the temperature of the air discharged from the press during compression. It reflects the heat transfer condition inside the press and is an important index for measuring the efficiency of the press. The press current refers to the current required by the press during operation. It reflects the power consumption of the press and is an important index for measuring the efficiency and running state of the press. The working parameters reach a certain target value, and the press frequency can be correspondingly adjusted.
S103, determining the adjustment amplitude of the press frequency according to the working parameters.
In this scheme, the adjustment range of press frequency is determined through operating parameter. Specifically, the adjustment amplitude is to adjust the original press frequency to the desired press frequency. For example, the original exhaust temperature is 60 degrees, and in the mode with the optimal opening capability, the exhaust temperature needs to reach 80 degrees, and the press frequency needs to be increased until the exhaust temperature reaches 80 degrees.
S104, adjusting the press frequency according to the adjustment mode and the adjustment amplitude of the press frequency.
In this scheme, according to adjusting mode and regulation range to press frequency regulation. Specifically, the adjustment mode determines whether to raise or lower the frequency of the press. The adjustment amplitude may be specific data for adjusting the press frequency. It should be noted that the present solution adjusts the press frequency by means of a segmented approach. By dividing the operating parameters into three ranges, each corresponding to a different press frequency. And if the current working parameter range reaches the next range, adjusting the frequency to the corresponding press frequency. If the current working parameter does not reach the range of the next working parameter after a period of adjustment, the adjustment is needed to be continued under the frequency. For example, the exhaust temperature is from 60 degrees to 90 degrees, and can be divided into 60 to 70, corresponding to 5Hz; 70-80, corresponding to 8HZ; 80-90, corresponding to 10HZ. At 60-70 ℃, each period rises by 5HZ; after the period is finished, if the exhaust temperature reaches 70-80 degrees, the exhaust temperature is increased by 8HZ per cycle, and after the period is finished, if the exhaust temperature does not reach 70-80 degrees, the exhaust temperature is increased by 5HZ continuously.
On the basis of the above embodiment, optionally, before the operation mode of the press is obtained, the method further comprises:
And determining the operation mode of the press according to the supply and demand data in the heat pump system.
In this solution, the supply and demand requirements of the heat pump system may be requirements that require hot water to be supplied. Specifically, when the user has a period of time for intensively using hot water, the mode of the heat pump system can be adjusted to an optimal capacity mode, namely a mode with higher efficiency of producing hot water; when the user has low hot water demand, the system can be adjusted to an energy efficiency optimal mode, namely a mode which saves more energy.
In the embodiment of the application, the optimal energy efficiency or capacity mode is selected according to the self requirements of the user, so that a large amount of heat can be supplied in a short time, and meanwhile, the energy consumption is saved in other time periods.
In the embodiment of the application, an operation mode of a press is obtained, and an adjustment mode of the press frequency is determined according to the operation mode; after the heat pump system is operated for a preset time, working parameters of the press are obtained; determining the adjustment amplitude of the press frequency according to the working parameters; and adjusting the press frequency according to the adjustment mode and the adjustment amplitude of the press frequency. The press frequency is adjusted by setting two modes, so that the original fixed frequency can be adjusted according to the needs of a user, a large amount of hot water can be supplied in a short time when the user needs, the energy consumption can be saved in the rest time, and the use needs of the user are met.
Example two

The scheme makes better improvement on the embodiment, and the specific improvement is as follows: acquiring an operation mode of a press, determining an adjustment mode of the press frequency according to the operation mode, and comprising the following steps: acquiring an operation mode of a press; if the operation mode is the first mode, determining that the adjustment mode of the press frequency is down-conversion adjustment; and if the operation mode is the second mode, determining that the adjustment mode of the press frequency is up-conversion adjustment. As shown in fig. 2, the method specifically comprises the following steps:
s1011, obtaining the operation mode of the press.
S1012, if the operation mode is the first mode, determining that the adjustment mode of the press frequency is down-conversion adjustment.
In this solution, the first mode may be an energy efficiency optimal mode. Specifically, when the user has little demand for hot water, the first mode is started, and the frequency of the press is subjected to frequency reduction. The exhaust temperature and press current are adjusted to be within the respective ranges by decrementing the corresponding press frequency per cycle. By performing frequency reduction treatment on the frequency of the press, system parameters such as exhaust temperature, press current and the like are adjusted, so that the heat pump system can achieve optimal energy efficiency in a short period, and the technical effect of energy conservation of the heat pump system is achieved.
And S1013, if the operation mode is the second mode, determining that the adjustment mode of the press frequency is up-conversion adjustment.
In this solution, the second mode may be a capacity optimal mode. Specifically, when the user has excessive hot water demand, the second mode is started, the frequency of the press is increased, and the exhaust temperature and the press current are adjusted to be within the corresponding ranges by increasing the corresponding press frequency every cycle. By performing frequency raising treatment on the frequency of the press, system parameters such as exhaust temperature, press current and the like are adjusted, so that the heat pump system can reach optimal capacity in a short period, and the temporary and large-scale hot water demands of users are met rapidly.
In the embodiments of the present application, improvements are made to the above embodiments. The concrete improvement is as follows: acquiring an operation mode of a press, determining an adjustment mode of the press frequency according to the operation mode, and comprising the following steps: acquiring an operation mode of a press; if the operation mode is the first mode, determining that the adjustment mode of the press frequency is down-conversion adjustment; and if the operation mode is the second mode, determining that the adjustment mode of the press frequency is up-conversion adjustment. The operation mode is obtained to determine that the adjustment mode is frequency-up or frequency-down, so that electricity saving or centralized hot water supply can be realized, and the requirements of users are met.

Fig. 3 is a flow chart of a press frequency control method of a heat pump system according to a third embodiment of the present application. The scheme makes better improvement on the embodiment, and the specific improvement is as follows: the working parameters of the press include: exhaust temperature and/or press current; correspondingly, determining the adjusting amplitude of the press frequency according to the working parameters comprises the following steps: determining the adjustment amplitude of the frequency of the press according to the temperature interval of the exhaust temperature; or determining the adjustment amplitude of the press frequency according to the current interval of the press current; or determining a first adjusting amplitude for the press frequency according to the current interval of the press current; determining a second adjusting amplitude for the press frequency according to the current interval of the press current; and determining the total adjustment amplitude of the press frequency according to the first adjustment amplitude and the second adjustment amplitude. As shown in fig. 3, the method specifically comprises the following steps:
s101, acquiring an operation mode of the press, and determining an adjustment mode of the press frequency according to the operation mode.
S102, after a heat pump system is operated for a preset time period, working parameters of the press are obtained; and performs one of S1031, S1032, and S1031.
S1031, determining the adjustment amplitude of the press frequency according to the temperature interval of the exhaust temperature.
In this scheme, can be according to the temperature interval that exhaust temperature belongs to, adjust press frequency. Specifically, the exhaust temperature is in different ranges, and the frequency values of the required frequency up-conversion or down-conversion are different. For example, the exhaust temperature is from 60 degrees to 90 degrees, and can be divided into 60 to 70, corresponding to 5Hz; 70-80, corresponding to 8HZ; 80-90, corresponding to 10HZ. At 60-70 ℃, each period rises by 5HZ; after the period is finished, if the exhaust temperature reaches 70-80 degrees, the exhaust temperature is increased by 8HZ per cycle, and after the period is finished, if the exhaust temperature does not reach 70-80 degrees, the exhaust temperature is increased by 5HZ continuously. Or the exhaust temperature is reduced from 90 degrees to 60 degrees and can be divided into 80-90, corresponding to 5Hz; 70-80, corresponding to 8HZ; 60-70, corresponding to 10HZ. At 80-90 degrees, each period is reduced by 5HZ; after the period is finished, the exhaust temperature is reduced by 8HZ per period when reaching 70-80 degrees, and after the period is finished, the exhaust temperature is reduced by 5HZ continuously when not reaching 70-80 degrees. It should be noted that the exhaust temperature must not be lower than 60 degrees and not exceed 115 degrees according to the specification.
S1032, or,
and determining the adjusting amplitude of the press frequency according to the current interval of the press current.
In this scheme, can be according to the electric current interval that the press electric current belonged to, adjust press frequency. Specifically, the press current is in different ranges, and the frequency values of the frequency up-conversion or the frequency down-conversion are different. For example, the press current is from 1A to 9A degrees, which can be divided into 1A to 3A, corresponding to 5Hz; 3A-6A, corresponding to 8HZ;6A to 9A, corresponding to 10HZ. Under 1A-3A, each period rises by 5HZ; after the period is finished, if the press current reaches 3A-6A, the frequency is increased by 8HZ per period, and after the period is finished, if the press current does not reach 3A-6A, the frequency is increased by 5HZ continuously. Or the current of the press is reduced from 9A to 1A and can be divided into 6A to 9A, which corresponds to 5Hz; 3A-6A, corresponding to 8HZ;1A to 3A correspond to 10HZ. At the temperature of 6A-9A, each period is reduced by 5HZ; after the period is finished, if the press current reaches 3A-6A, 8HZ is reduced per period, and after the period is finished, if the press current does not reach 3A-6A, 5HZ is continuously reduced.
S1033, or alternatively,
determining a first adjustment amplitude for the press frequency according to a temperature interval to which the exhaust temperature belongs; determining a second adjusting amplitude for the press frequency according to the current interval of the press current; and determining the total adjustment amplitude of the press frequency according to the first adjustment amplitude and the second adjustment amplitude.
In this scheme, can also adjust the press frequency according to exhaust temperature and press electric current simultaneously. For example, the exhaust temperature is from 60 to 70, the press current is from 1A to 3A, the exhaust temperature is raised to 5HZ, and the press current is raised to 5HZ.
S104, adjusting the press frequency according to the adjustment mode and the adjustment amplitude of the press frequency.
On the basis of the embodiment, optionally, the temperature range is at least two; the adjusting amplitude of the press frequency corresponding to each temperature interval is predetermined;
correspondingly, according to the temperature interval of the exhaust temperature, determining the adjusting amplitude of the press frequency comprises the following steps:
if the temperature interval is a target temperature interval, determining the adjusting amplitude of the press frequency according to the target temperature interval, and stopping adjusting;
if the temperature interval is not the target temperature interval, determining the adjusting amplitude of the press frequency according to the temperature interval, and continuing adjusting until the temperature interval is the target temperature interval, so as to terminate the adjusting.
In this embodiment, the target temperature range is a final range of the exhaust temperature. Specifically, whether the current exhaust temperature is in the last exhaust temperature range is judged, if the exhaust temperature is not in the last exhaust temperature range, the frequency is continuously adjusted according to the current range, and if the exhaust temperature is in the last exhaust temperature range, the frequency adjustment can be terminated. For example, the exhaust temperature is from 60 degrees to 90 degrees, and can be divided into 60 to 70, corresponding to 5Hz; 70-80, corresponding to 8HZ; 80-90, corresponding to 10HZ. When the exhaust temperature is between 60 and 80, the adjustment is performed according to the respective corresponding frequency, and if the exhaust temperature is recognized to be within the range of 80 to 90 degrees, the adjustment is stopped.
In the embodiment of the application, the frequency adjustment is stopped by reaching the preset exhaust temperature range, so that the utilization rate of the heat pump in the system is improved.
On the basis of the embodiment, optionally, the current interval is at least two; the adjustment amplitude of the press frequency corresponding to each current interval is predetermined;
correspondingly, according to the current interval of the press current, determining the adjusting amplitude of the press frequency comprises the following steps:
if the current interval is a target current interval, determining the adjusting amplitude of the press frequency according to the target current interval, and stopping adjusting;
if the current interval is not the target current interval, determining the adjusting amplitude of the press frequency according to the current interval, and continuing adjusting until the current interval is the target current interval, so as to terminate the adjusting.
In this scheme, the target current interval is the final range interval of the press current. Specifically, whether the current press current is in the last press current range is judged, if the press current is not in the last press current range, the frequency is continuously adjusted according to the current range, and if the press current is in the last press current range, the press frequency adjustment can be stopped. For example, the press current is from 1A degree to 9A degrees, and can be divided into 1A to 3A, corresponding to 5Hz; 3A-6A, corresponding to 8HZ;6A to 9A, corresponding to 10HZ. When the press current is between 1A and 6A, the adjustment is performed according to the respective corresponding frequency, and if the press current is recognized to be in the interval of 6A to 9A, the adjustment is stopped.
In the embodiment of the application, the frequency adjustment is stopped by reaching the preset press current range, so that the utilization rate of the heat pump in the system is improved.
On the basis of the above embodiment, optionally, the adjustment period of the press frequency is 30 seconds.
In this scheme, the adjustment period of the press frequency should be 30 seconds, that is, every 30 seconds, the current working parameter is obtained, and the frequency is determined according to the obtained working parameter to start a new adjustment. By multiplying the press frequency in each range by the period and adding the total frequency of each period, the total frequency that needs to be adjusted in this mode can be obtained. Meanwhile, the total operating frequency of the heat pump is equal to the natural frequency plus the adjusting total frequency, and the calculated adjusting total frequency is added with the natural frequency to obtain the total operating frequency of the heat pump press in the mode.
In the embodiments of the present application, improvements are made to the above embodiments. The concrete improvement is as follows: the working parameters of the press include: exhaust temperature and/or press current; correspondingly, determining the adjusting amplitude of the press frequency according to the working parameters comprises the following steps: determining the adjustment amplitude of the frequency of the press according to the temperature interval of the exhaust temperature; or determining the adjustment amplitude of the press frequency according to the current interval of the press current; or determining a first adjusting amplitude for the press frequency according to the current interval of the press current; determining a second adjusting amplitude for the press frequency according to the current interval of the press current; and determining the total adjustment amplitude of the press frequency according to the first adjustment amplitude and the second adjustment amplitude. By setting the adjusting period of the frequency of the press, the total frequency of the heat pump operation can be obtained, and the effect of meeting the user requirement is achieved.
