[0044] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] Figure 1 is a schematic diagram of the system structure of a heat pump system according to an embodiment of the present invention. Figure 1As shown, the heat pump system includes a heat pump hot water unit, a buffer water tank, a diverter and heating devices (which may be air discs, floor heating or others) in each area (such as a room). The partition control device is correspondingly arranged on the water inlet pipe and the water outlet pipe of the heating device that is diverted by the diverter to each area. Hot water passes through the partition control device from the buffer water tank and enters the heating device (radiator, floor heating, etc.) in each room. After the water temperature becomes low due to heat exchange, it returns to the buffer water tank through the partition control device. Heating of each room is achieved, wherein the partition control device corresponding to each room can implement a partition control scheme, which can meet the different user needs of multiple areas / rooms at the same time.

[0047] Figure 2 is a schematic diagram of the structure of a partition control device according to an embodiment of the present invention. Figure 2 As shown, the zoning control device includes: a water pump, which is arranged on the water inlet pipe of the heating device of the area; a three-way valve, whose first inlet is connected to the water inlet pipe of the diverter to the area, whose second inlet is connected to the water outlet pipe of the heating device of the area, and whose outlet is connected to the water inlet pipe of the heating device; and a thermostat, which is used to control the opening of the three-way valve.

[0048] In this embodiment, a zoning control device is provided on the water inlet pipe and the water outlet pipe of the heating device that is diverted to each area by the diverter to realize a zoning control scheme. It can meet the different user needs of multiple areas / rooms at the same time, and the installation is simple and cost-saving. In addition, the adaptive adjustment of the ambient temperature can be realized through the environment-dependent function on the thermostat. Based on this, the zoning control device of this embodiment also includes: a thermostat, which is specifically used to obtain the actual temperature of the area and the target temperature of the area, and control the opening of the three-way valve according to the actual temperature of the area and the target temperature of the area. The thermostat is also used to generate the regional target temperature according to the ambient temperature. The zoning control device also includes: an outlet water temperature sensing package, which is arranged on the water inlet pipe of the heating device of the area, and is used to detect the regional target temperature. The above functions of the thermostat can realize the adaptive adjustment of the heat pump system based on the ambient temperature, which is conducive to reducing the energy consumption of the heat pump system and improving user experience satisfaction.

[0049] Figure 3 Schematic diagram of the structural connection relationship of the partition control device according to an embodiment of the present invention. Figure 3As shown, the thermostat is equipped with an environmental temperature sensing package and a water outlet temperature sensing package, which are installed in the room and in the room water outlet pipe respectively. In the partition control device designed in this embodiment, the water pump and the three-way valve (proportional three-way valve) should control the water inlet pipe of the room separately, and the three-way valve is also connected to the water outlet pipe. The user can set the adjustment of the water pump gear on the thermostat, and adjust the inlet and outlet water to achieve the adjustment of the temperature of a single room by controlling the water pump and the three-way valve. In addition, the temperature of the return water can also be used to mix the incoming water, and after such a cycle, the indoor temperature finally reaches the regional target temperature. Specifically, the hot water in the buffer water tank enters the water inlet pipe of the area through the three-way valve (such as a proportional three-way valve) and the water pump of the partition control device of each area. After heat exchange, the temperature is reduced and becomes cold water. Part of the cold water returns to the main outlet pipe, and part of the cold water flows back to the three-way valve and mixes with the incoming water, thereby realizing the use of the temperature of the return water to mix the incoming water, and after multiple cycles, the room temperature is raised to the regional target temperature.

[0050] Example 2

[0051] According to an embodiment of the present invention, a partition control method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0052] Figure 4 is a flow chart of a partition control method according to an embodiment of the present invention. Figure 4 As shown, the method comprises the following steps:

[0053] Step S401, during the startup phase of the heat pump system, adjusting the opening of the three-way valve of the zone control device in each zone according to the actual temperature and target temperature of each zone;

[0054] Step S402, thereafter, according to the change of the actual temperature of the area, the opening of the three-way valve of the partition control device in the area is adjusted.

[0055] This embodiment provides a zoning control scheme for a heat pump system, which is divided into a coarse control strategy and a fine control strategy. Step S401 is a coarse control strategy after the heat pump system is turned on (within a period of time after the power-on, such as 3 minutes), and step S402 is a fine control strategy thereafter. This embodiment can simultaneously meet the needs of different users in multiple rooms, is simple to install and saves costs.

[0056] The coarse control strategy and fine control strategy of the heat pump system are different in different operation modes. The coarse control strategy and fine control strategy in different operation modes are introduced in detail below.

[0057] 1) Heating mode

[0058] Coarse control strategy:

[0059] In the heating mode, according to the actual temperature and target temperature of each zone, the opening of the three-way valve of the zone control device in the zone is adjusted. Specifically:

[0060] Calculate the room temperature difference θ = T 区域 -T 设 ; Among them, T 区域 is the actual temperature of the region, T 设 is the target temperature of the area; the adjusted opening of the three-way valve is determined according to the room temperature difference; wherein, the greater the room temperature difference, the smaller the adjusted opening.

[0061] The larger θ is, the less it is necessary to import hot water from the whole machine into the room pipeline, so the opening of the three-way valve is smaller.

[0062] Table 1 is a comparison table of the opening of the three-way valve and the room temperature difference θ in the heating mode.

[0063] Table 1

[0064]

[0065]

[0066] Based on this, the opening of the three-way valve is stabilized through a rough control strategy within 3 minutes after the heat pump system is started to ensure that the room temperature rises quickly.

[0067] Fine-grained control strategy:

[0068] According to the difference between the actual temperature of the area and the target temperature, adjust the opening of the three-way valve of the partition control device in the area, specifically:

[0069] Periodically obtain the difference T between the regional temperature and the target temperature 变 ; if T 变 If T is in the preset range [-k, k], the opening of the three-way valve is maintained unchanged; 变 >k, then according to T 变 The interval corresponds to the adjustment of the opening of the three-way valve; among them, T 变 The larger the value, the smaller the opening after adjustment. 变 <-k, then according to T 变 The interval corresponds to the adjustment of the opening of the three-way valve; among them, T 变 The smaller it is, the larger the opening will be after adjustment.

[0070] T 变 The larger it is, the better the heating effect is, which means that the whole machine does not need hot water to be introduced into the area (room) through pipelines, so the opening of the small three-way valve should be opened.

[0071] Table 2 shows the three-way valve opening adjustment and T in heating mode. 变 Comparison table.

[0072] Table 2

[0073]

[0074]

[0075] The above-mentioned fine control strategy is executed after the rough control strategy of the initial period (for example, 3 minutes) of the heat pump system startup. The fine control strategy can achieve more precise control and adjustment of the room temperature, thereby further improving the user experience in the room. The fine control strategy can be set to adjust once every t seconds, t is adjustable from 30 to 300. The smaller t is, the faster the adjustment speed and the more frequent the three-way valve action. The environment-dependent function on the thermostat can also be used to achieve adaptive adjustment of the ambient temperature, which is conducive to reducing the energy consumption of the heat pump system and improving user experience satisfaction.

[0076] 2) Cooling mode

[0077] Coarse control strategy:

[0078] According to the actual temperature and target temperature of each area, adjust the opening of the three-way valve of the zoning control device in the area, specifically:

[0079] Calculate the room temperature difference θ = T 区域 -T 设 ; Among them, T 区域 is the actual temperature of the region, T 设 is the target temperature of the area; the adjusted opening of the three-way valve is determined according to the room temperature difference; wherein, the greater the room temperature difference, the greater the adjusted opening.

[0080] The water temperature of the hot water unit can be lowered by adding refrigerant. In cooling mode, the water temperature circulating in the entire pipeline is low. The larger θ is, the more low-temperature water from the pipeline needs to be introduced into the room, so the opening of the three-way valve is larger. Based on this, the opening of the three-way valve is stabilized within 3 minutes after the heat pump system is turned on through a rough control strategy.

[0081] Table 3 is a comparison table of the opening of the three-way valve and the room temperature difference θ in the cooling mode.

[0082] Table 3

[0083]

[0084]

[0085] Based on this, the opening of the three-way valve is stabilized through a rough control strategy within 3 minutes after the heat pump system is started to ensure that the room temperature drops rapidly.

[0086] Fine-grained control strategy:

[0087] According to the difference between the actual temperature of the area and the target temperature, adjust the opening of the three-way valve of the partition control device in the area, specifically:

[0088] Periodically obtain the difference T between the regional temperature and the target temperature 变 ; if T 变 If T is in the preset range [-k, k], the opening of the three-way valve is maintained unchanged; 变 >k, then according to T 变 The interval corresponds to the adjustment of the opening of the three-way valve; among them, T 变 The larger the value, the larger the opening after adjustment; if T 变 <-k, then according to T 变 The interval corresponds to the adjustment of the opening of the three-way valve; among them, T 变 The smaller it is, the smaller the opening will be after adjustment.

[0089] Table 4 is the three-way valve opening adjustment and T in cooling mode 变 Comparison table.

[0090] Table 4

[0091]

[0092]

[0093] The above-mentioned fine control strategy is executed after the rough control strategy of the initial period (for example, 3 minutes) of the heat pump system startup. The fine control strategy can achieve more precise control and adjustment of the room temperature, thereby further improving the user experience in the room. The fine control strategy can be set to adjust once every t seconds, t is adjustable from 30 to 300. The smaller t is, the faster the adjustment speed and the more frequent the three-way valve action. The environment-dependent function on the thermostat can also be used to achieve adaptive adjustment of the ambient temperature, which is conducive to reducing the energy consumption of the heat pump system and improving user experience satisfaction.

[0094] It should be noted that, before executing the coarse control strategy and the fine control strategy, in order to achieve more accurate control and to meet the different temperature requirements for each area, the regional target temperature of each area can be determined in advance. In order to improve the adaptive adjustment of the heat pump system to the variable ambient temperature, the regional target temperature of this embodiment can be determined based on the ambient temperature, and the ambient temperature is obtained; the regional target temperature of each area is generated according to the ambient temperature. This can ensure the adaptive adjustment of the heat pump system to the variable ambient temperature.

[0095] Regarding how to generate the regional target temperature of each region according to the ambient temperature, this embodiment provides a preferred implementation, namely:

[0096] If the ambient temperature T 环境 ≤T 节能模式环温下限 , then the regional target temperature T is generated 设 =T 设定区域温度上限 ;

[0097] If the ambient temperature T 环境 ≥T 节能模式环温上限 , then the regional target temperature T is generated 设 =T 设定区域温度下限 ;

[0098] If T 节能模式环温下限 <T 环境 <T 节能模式环温上限 , then according to T 环境 , T 节能模式环温上限 , T 节能模式环温下限 , T 设定区域温度上限 and T 设定区域温度下限 Calculate the regional target temperature T 设 , achieved through the following formula:

[0099]

[0100] It should be noted that the thermostat of each zone is independent. 节能模式环温上限 , T 节能模式环温下限 , T 设定区域温度上限 and T 设定区域温度下限 Parameters such as temperature can be set to different values ​​according to different user needs, different regional application scenarios, and different devices in the region (for example, some devices need to be used at lower temperatures). Therefore, the target temperature generated in each region is also different. Based on this, the target temperature required for each region can be calculated based on the ambient temperature and the different needs of each region. This can achieve more accurate temperature control and meet the different temperature requirements for each region.

[0101] Example 3

[0102] This embodiment takes the heat pump system operating in the heating mode as an example, and takes the area as a room as an example to introduce the zoning control scheme for different rooms. The specific implementation method of this embodiment is as follows:

[0103] The first step is to get the temperature T detected by the room temperature sensor. 房间 .

[0104] In the second step, after the heat pump hot water unit is turned on, the thermostat starts to control the water pump to start, and the hot water generated by the unit is introduced into the room pipeline. The user sets the room target temperature T on the thermostat. 设, actual room temperature difference θ=T 房间 -T 设 The larger the θ is, the less it is necessary to introduce hot water from the whole machine into the room pipeline, so the opening of the proportional adjustment three-way valve is smaller, and the opening is stabilized through rough adjustment within 3 minutes of starting the machine.

[0105] The third step is to enter the proportional adjustment three-way valve fine adjustment control 3 minutes after startup. Adjust once every t seconds, t is adjustable from 30 to 300. The smaller t is, the faster the adjustment speed is and the more frequent the three-way valve action is.

[0106] Fine adjustment control is to adjust the three-way valve opening by increasing or decreasing the ratio after calculating the room temperature difference, and the room temperature difference is updated in real time. In heating mode, the larger the room temperature difference, the better the heating effect, which means that it is less necessary to import hot water from the whole machine into the room pipeline, so the three-way valve opening should be adjusted in a small ratio. In cooling mode, the smaller the room temperature difference, the better the cooling effect, which means that it is less necessary to import cold water from the whole machine into the room pipeline, so the three-way valve opening should be adjusted in a small ratio.

[0107] The user can set the water pump gear on the thermostat, and adjust the water inlet and outlet to meet the different temperature requirements of a single room by controlling the water pump and the proportional adjustment three-way valve. The return water temperature is used to mix the incoming water, and the target temperature is finally reached after such a cycle.

[0108] One zone control device can support the temperature differentiation of one area. If multiple different areas are required, multiple zone control devices are required.

[0109] In addition, the environment-dependent function can be set on the thermostat, that is, the room target temperature T is automatically generated according to the ambient temperature. It can be viewed through the thermostat and manual change of the target temperature is not allowed. This achieves adaptive adjustment of the ambient temperature, which is beneficial to reducing the energy consumption of the heat pump system.

[0110] 1) When T 环境 ≤T 节能模式环温下限 When T 设 =T 设定房间温度上限 ;

[0111] 2) When T 环境 ≥T 节能模式环温上限 When T 设 =T 设定房间温度下限 ;

[0112] 3) When T 节能模式环温下限 <T 环境 <T 节能模式环温上限 , set the temperature to:

[0113]

[0114] Specific example: T 设定房间温度上限The setting range is 22~30℃ 、 T 设定房间温度下限 The setting range is 18~21℃, T 节能模式环境温度上限 The setting range is 10~37℃, T 节能模式环境温度下限 The setting range is -20~9℃.

[0115] Assume that T 设定房间温度上限 =25℃、T 设定房间温度下限 =20℃、T 节能模式环境温度上限 =25℃、T 节能模式环境温度下限 =9℃. When T 环境 =31℃, T 设 =20℃; when T 环境 =8℃, T 设 =25℃; when T 环境 =29℃, round off to get T 设 =21℃

[0116] This embodiment proposes a zoning control scheme for a heat pump system, in which zoning control devices are provided on the water inlet and outlet pipes of the heating device that is diverted to each area by the diverter, so as to realize the zoning control scheme. It can not only meet the different user needs of multiple areas / rooms at the same time, but also be simple to install and save costs. It can also realize adaptive adjustment of the ambient temperature through the environment-dependent function on the thermostat, which is conducive to reducing the energy consumption of the heat pump system and improving user experience satisfaction.
