If the air energy heat pump unit adopts a highly corrosion-resistant condenser, the overall cost will be very high.

[0045] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of some known functions and known components.

[0046] The embodiments of the present application provide a non-decay sterilization and scale prevention heat pump system.

[0047] Figure 1This is a module structure diagram of a non-attenuation sterilization and anti-scaling heat pump system according to an embodiment of the application, as shown in FIG. Figure 1 As shown, a non-attenuation sterilization and anti-scaling heat pump system of an embodiment of the application includes:

[0048] The scaling generating unit 100 is configured to connect the compressor exhaust port of the heat pump unit and the four-way valve;

[0049] The flow control unit 101 is configured to be connected to the water inlet and outlet of the unit condenser and the water inlet and outlet of the scaling generating unit 100, respectively, and is used to control the opening of the water inlet and outlet channels of the water inlet and outlet; wherein the water inlet and outlet include a water inlet and a water outlet;

[0050] A controllable cleaning unit 102 is configured to be connected to the water inlet and outlet of the scaling generating unit 100 for cleaning the scaling generating unit 100;

[0051] The temperature detection unit 103 is configured to respectively detect the exhaust temperature of the compressor exhaust port, the water outlet temperature of the unit condenser outlet, and the high-temperature water outlet temperature of the scaling generating unit 100 outlet.

[0052] like Figure 1 As shown, the scaling unit 100 is connected to the compressor exhaust port of the heat pump unit and the four-way valve, replacing the scaling of the heat pump unit condenser and transferring the scaling that would have otherwise formed on the heat pump unit condenser to the scaling unit 100. Accordingly, the flow control unit 101 adjusts the scaling conditions of the scaling unit 100 by controlling the openings of the inlet and outlet water channels of the scaling unit 100. The temperature detection unit 103 determines whether the scaling conditions of the scaling unit 100 need to be adjusted or cleaned based on the detected values ​​of each temperature, and further cleans the scaling unit 100 through the controllable cleaning unit 102 or adjusts the scaling conditions through the flow control unit 101.

[0053] The scaling unit 100 uses hardware similar to that of the heat pump unit condenser as a replacement for the scaling site of the condenser. Preferably, the scaling unit 100 also uses a condenser.

[0054] Figure 2 The schematic diagram of a non-attenuation sterilization and anti-scaling heat pump system of a preferred embodiment is as follows: Figure 2 As shown, the fouling generating unit 100 is an additional condenser;

[0055] The inlet of the additional condenser is connected to the exhaust port of the compressor, the outlet is connected to the D port of the four-way valve, and the water inlet and outlet are respectively connected to the flow control unit 101.

[0056] like Figure 2As shown, the additional condenser is connected to the exhaust of the compressor of the heat pump unit and connected to the D port of the four-way valve, as the main body of scale formation, and does not affect the normal operation of the heat pump unit during cleaning and maintenance, so that the heat pump unit does not produce performance degradation due to condenser scale formation.

[0057] As one of the preferred embodiments, the additional condenser uses a small condenser to reduce the cost of deploying hardware while scale is condensed on the additional condenser.

[0058] As one of the preferred embodiments, the additional condenser uses a high-temperature condenser to prepare high-temperature hot water for a long time, and kill bacteria in water through a circulating mode.

[0059] As one of the preferred embodiments, the additional condenser uses a corrosion-resistant condenser, such as a titanium tube condenser, to avoid corrosion of the cleaning liquid of the controllable cleaning unit 102, and to improve reliability and durability.

[0060] Preferably, as shown, Figure 2 The flow control unit 101 includes:

[0061] The circulating hand valve is connected to the water outlet of the scale formation unit 100 at one end and connected to the water outlet of the unit condenser at the other end.

[0062] The circulating hand valve is used to control the on-off of the water inlet and outlet channel, and is used to turn on or turn off the water inlet and outlet channel according to the control signal. As shown, Figure 2 The additional condenser is connected in parallel with the water inlet and outlet of the heat pump unit condenser, and the water inlet and outlet channel is controlled by the circulating hand valve.

[0063] Preferably, as shown, Figure 2 The flow control unit 101 further includes:

[0064] The circulating proportional integral valve is connected to the water inlet of the scale formation unit 100 at one end and connected to the water inlet of the unit condenser at the other end.

[0065] The circulating proportional integral valve controls the opening degree of the water inlet and outlet channel according to the control signal, and realizes the flow control of the water inlet and outlet channel.

[0066] The circulating proportional integral valve adjusts the opening degree of the water inlet and outlet channel through proportional adjustment of the opening degree, cooperates with the sensible heat of the exhaust of the heat pump unit compressor, realizes the preparation and adjustment of high-temperature water, realizes scale formation and sterilization, and protects the heat pump unit condenser from heat exchange attenuation caused by scale formation.

[0067] Preferably, as shown, Figure 2 The controllable cleaning unit 102 includes:

[0068] A first cleaning hand valve, one end of which is connected to the water inlet of the scaling generating unit 100;

[0069] A second hand-washing valve, one end of which is connected to the water outlet of the scaling generating unit 100;

[0070] The cleaning equipment is respectively connected to the other end of the first hand cleaning valve and the other end of the second hand cleaning valve.

[0071] like Figure 2 As shown, when the first and second wash hand valves are opened in response to a control signal, a cleaning fluid passage is formed between the cleaning device and the additional condenser, through which the cleaning fluid can clean the additional condenser. When the first and second wash hand valves are closed in response to a control signal, the cleaning device stops cleaning.

[0072] Preferably, when the first cleaning hand valve and the second cleaning hand valve are opened, the corresponding circulation hand valve and circulation proportional integral valve are closed to prevent the cleaning fluid of the cleaning equipment from affecting the condenser of the heat pump unit, thereby playing an isolation and protection role.

[0073] Preferably, if Figure 2 As shown, the temperature detection unit 103 includes:

[0074] A first temperature sensor (exhaust temperature) provided at the exhaust port of the compressor;

[0075] A second temperature sensor (water inlet temperature) is provided at the water inlet of the condenser of the unit;

[0076] A third temperature sensor (water outlet temperature) is provided at the water outlet of the condenser of the unit;

[0077] A fourth temperature sensor (high-temperature outlet water temperature) is provided at the water outlet of the scaling generating unit 100 .

[0078] In the control method of the embodiment of the present application, the non-attenuation sterilization and anti-scaling heat pump system is controlled accordingly by collecting and processing the above four temperatures.

[0079] The non-decay sterilization and scale prevention heat pump system of the embodiment of the present application comprises a scale formation unit 100 configured to connect the compressor exhaust port of the heat pump unit and the four-way valve, a flow control unit 101 configured to connect the water inlet and outlet ports of the unit condenser and the water inlet and outlet ports of the scale formation unit 100 respectively, a controllable cleaning unit 102 configured to connect the water inlet and outlet ports of the scale formation unit 100, and a temperature detection unit 103. The temperature detection unit 103 can detect the exhaust temperature of the compressor exhaust port, the outlet water temperature of the unit condenser outlet water port, and the high-temperature outlet water temperature of the scale formation unit 100 respectively, and provide a cleaning control basis for the controllable cleaning unit 102. By actively scaling the scale formation unit 100, the scaling of the heat pump unit condenser is avoided, and the heat pump unit does not need to be cleaned, thereby ensuring the normal operation of the heat pump system. At the same time, as a bypass, the scale formation unit 100 can be cleaned according to the cleaning control basis to maintain continuous operation.

[0080] Based on the non-decay sterilization and scale prevention heat pump system of the embodiment of the present application, the present application further provides a control method of the non-decay sterilization and scale prevention heat pump system.

[0081] Figure 3 The flow chart of the control method of the non-decay sterilization and scale prevention heat pump system of the embodiment of the present application is shown in FIG. 1. Figure 3 The control method of the non-decay sterilization and scale prevention heat pump system of the embodiment of the present application comprises steps S100 to S102.

[0082] S100, obtaining the exhaust temperature, the outlet water temperature, and the high-temperature outlet water temperature, determining a first temperature difference between the exhaust temperature and the outlet water temperature, and determining a second temperature difference between the exhaust temperature and the high-temperature outlet water temperature;

[0083] S101, when the first temperature difference is greater than or equal to a set temperature difference, determining an adjustment range for adjusting the inlet and outlet water passage opening degree of the scale formation unit according to the second temperature difference;

[0084] S102, when the first temperature difference is less than the set temperature difference, setting the inlet and outlet water passage opening degree to a set opening degree and cleaning the scale formation unit.

[0085] Preferably, Figure 4 The flow chart of the control method of the non-decay sterilization and scale prevention heat pump system of the preferred embodiment is shown in FIG. 1. Figure 4 The process of determining the adjustment range for adjusting the inlet and outlet water passage opening degree of the scale formation unit according to the second temperature difference when the first temperature difference is greater than or equal to the set temperature difference in step S101 comprises step S200.

[0086] S200, after adjusting the water inlet and outlet passage opening degree to the set opening degree and maintaining the set control period, dynamically updating the second temperature difference according to the set period to determine the adjustment range of the water inlet and outlet passage opening degree of the scale formation unit.

[0087] As one of the optional embodiments, as shown in Figure 4 The control method of the non-fading sterilization and scale prevention heat pump system of a preferred embodiment further comprises the step S201:

[0088] S201, setting the optimal scale formation temperature difference and sterilization temperature of the scale formation unit.

[0089] For example, set the target optimal high-temperature condenser scale formation temperature difference ▲T1 = high-temperature outlet water temperature - outlet water temperature, preferably 10℃; set the target sterilization temperature = 70℃ (preferably). It should be noted that the optimal scale formation temperature difference and sterilization temperature can be selected and adjusted according to the type of heat pump unit. Figure 2

[0090] Before step S100, the circulating hand valve is opened by default, the circulating proportional integral valve is closed by default, and the cleaning hand valves 1 and 2 are closed by default. After the heat pump unit is started and runs for a first set period of time, it enters a stable state, at which time the temperature difference between the exhaust temperature and the outlet water temperature of the heat pump unit is detected, i.e. the first temperature difference.

[0091] If the exhaust temperature - outlet water temperature ≥ set temperature difference, it is considered that the unit enters the optimal scale formation control strategy at this time, at which time the circulating proportional integral valve is opened at the reference set value, and after running for a second set period of time, the temperature difference between the exhaust temperature and the high-temperature outlet water temperature is adjusted.

[0092] Preferably, the reference set value is 5-15%, preferably 10%.

[0093] Preferably, the first set period of time is 3-7min, preferably 5min.

[0094] Preferably, the second set period of time is 30-90s, preferably 60s.

[0095] Preferably, the adjustment range of the water inlet and outlet passage opening degree of the scale formation unit is adjusted according to the second temperature difference according to the set period.

[0096] Wherein, the second temperature difference and the adjustment range have a corresponding relationship, and preferably, the adjustment range of the water inlet and outlet passage opening degree of the scale formation unit is adjusted according to the second temperature difference as shown in Table 1:

[0097] Table 1 Adjustment range preferred table

[0098]

[0099] ​As shown in Table 1, the adjustment range for the opening of the inlet and outlet water channels of the scaling unit is determined based on the second temperature difference range to adjust the opening of the inlet and outlet water channels. It should be noted that the corresponding relationship between the adjustment range and the second temperature difference can be adjusted based on the selection of the heat pump unit and the additional condenser, and is not a single limitation here.

[0100] If the exhaust temperature - the outlet water temperature is less than the set temperature difference, it is considered that the heat pump unit state cannot enter the optimal scaling condition at this time. At this time, the circulating proportional integral valve maintains the reference set value opening.

[0101] When cleaning the scaling unit, control the circulation proportional integral valve and circulation manual valve to be closed, open the cleaning manual valves 1 and 2, and add cleaning fluid for cleaning.

[0102] The control method for the non-attenuation sterilization and anti-scaling heat pump system of the present application is based on the non-attenuation sterilization and anti-scaling heat pump system. The method obtains the exhaust temperature, outlet water temperature, and high-temperature outlet water temperature, determines a first temperature difference between the exhaust temperature and the outlet water temperature, and determines a second temperature difference between the exhaust temperature and the high-temperature outlet water temperature. When the first temperature difference is greater than or equal to a set temperature difference, the adjustment range for adjusting the opening of the inlet and outlet water channels of the scaling generating unit is determined based on the second temperature difference. When the first temperature difference is less than the set temperature difference, the opening of the inlet and outlet water channels is set to the set opening and the scaling generating unit is cleaned. Based on this, the scaling generating unit is cleaned in a controlled manner, ensuring the operating effect and efficiency of the non-attenuation sterilization and anti-scaling heat pump system.
