Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a humidity control method and device for refrigeration equipment, refrigeration equipment, storage medium, and electronic equipment. Background Art

[0002] In the related technology, the market uses wet film humidifiers to humidify, replenish water and preserve flowers, fruits and vegetables. Since wet film humidification is a method of air humidification, it increases the humidity in the air through the contact between water and air. When dry air passes through the moist wet film, water will evaporate from the surface of the wet film into the air, thereby increasing the humidity of the air. It is a low-temperature evaporative humidification. At normal temperature and low temperature, the humidification effect will be low. If the evaporation water temperature is directly increased, the indoor temperature will rise, affecting the cooling effect.

[0039] In this embodiment, a humidity control method for a refrigeration device is provided. Figure 2 FIG. 1 is a flow chart of a humidity control method for a refrigeration device according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0040] Step S202, detecting the indoor humidity and indoor temperature of a refrigeration device, and determining a set temperature and set humidity of the refrigeration device, wherein the refrigeration device includes a refrigeration component and a wet film humidifier;

[0041] The indoor humidity and indoor temperature of this embodiment are the real-time temperature and humidity of the working area of the refrigeration equipment (such as in a room or a warehouse). The refrigeration equipment performs cooling and humidification at the same time. The refrigeration component of the refrigeration equipment is used for cooling, and the wet film humidifier is used for humidification. The refrigeration component includes a compressor, a condenser, an evaporator, etc.

[0042] Step S204, determining whether the indoor humidity is less than the set humidity;

[0043] Step S206: If the indoor humidity is lower than the set humidity, start the wet film humidifier and control the evaporation water temperature of the wet film humidifier according to the indoor temperature and the set temperature, wherein the evaporation water temperature is positively correlated with the humidification efficiency;

[0044] By increasing the evaporation water temperature of the wet film humidifier by heating, the speed at which water evaporates from the wet film surface into the air can be increased, thereby improving the humidification efficiency.

[0045] Through the above steps, the indoor humidity and indoor temperature of the refrigeration equipment are detected, and the set temperature and set humidity of the refrigeration equipment are determined, wherein the refrigeration equipment includes a refrigeration component and a wet-film humidifier; it is judged whether the indoor humidity is less than the set humidity; if the indoor humidity is less than the set humidity, the wet-film humidifier is started, and the evaporation water temperature of the wet-film humidifier is controlled according to the indoor temperature and the set temperature, wherein the evaporation water temperature is positively correlated with the humidification efficiency. When humidification is required, the evaporation water temperature of the wet-film humidifier is controlled according to the indoor temperature and the set temperature, which solves the technical problem of low humidification efficiency of the wet-film humidifier in the related art, and improves the humidification efficiency of the wet-film humidifier while taking into account the refrigeration effect.

[0046] Figure 3This is a piping diagram of a refrigeration device in an embodiment of the present invention, wherein the refrigeration device includes a compressor (01); a gas-liquid separator (02); an air cooler (03); a drying filter (04); an oil-gas separator (05); a condenser (06); a water pump (07); a wet film humidifier (08); a filter (09); a heat exchanger (10); an electronic expansion valve (V01); a solenoid valve 1 (V02); a solenoid valve 2 (V03); a flow regulating valve 1 (V04); a flow regulating valve 2 (V05); a hot gas bypass valve (V06); a flow regulating valve 3 (V07); a temperature sensor 1 (T01), corresponding to a first temperature sensor; and a temperature sensor 2 (T02), corresponding to a second temperature sensor.

[0047] When the refrigeration equipment is working, the water pump (07) sends fresh water into the condenser (06) to exchange heat with the high-temperature and high-pressure gas generated by the compressor (01). The fresh water is heated for the first time, filtered by the filter (09), and then reaches the heat exchanger (10) through the flow control valve 1 (V04). It exchanges heat with the high-temperature and high-pressure gas generated by the compressor (01) for the second time, and enters the wet film humidifier (08) for humidification through the control of the solenoid valve; the high-temperature and high-pressure gas generated by the compressor (01) enters the oil-gas separator (05) through the pipeline, and a part of the The high-temperature and high-pressure gas enters the condenser (06) for heat exchange and becomes a medium-temperature and high-pressure liquid. After passing through the drying filter (04), it passes through the electronic expansion valve (V01) and becomes a low-temperature and low-pressure liquid. After entering the air cooler (03) for evaporative cooling, it becomes a low-temperature and low-pressure gas and passes through the gas-liquid separator (02) and returns to the compressor (01). The other part of the high-temperature and high-pressure gas passes through the flow regulating valve 2 (05) and reaches the heat exchanger (10). After heat exchange with fresh water, it passes through the hot gas bypass valve (06) and returns to the compressor (01).

[0048] In one implementation of this embodiment, controlling the evaporation water temperature of the wet-film humidifier according to the indoor temperature and the set temperature includes: obtaining a first temperature detected by a first temperature sensor, and obtaining a second temperature detected by a second temperature sensor, wherein the first temperature sensor is installed at the inlet of a heat exchanger and the second temperature sensor is installed at the outlet of the heat exchanger, and the heat exchanger is used to heat the inlet water of the wet-film humidifier; and controlling the evaporation water temperature of the wet-film humidifier according to the first temperature, the second temperature, the indoor temperature, and the set temperature.

[0049] The first temperature is the water temperature before the heat exchanger is heated, and the second temperature is the water temperature after the heat exchanger is heated. The system sets the operating temperature T of the refrigeration equipment and the operating humidity W, where T and W are range values to avoid frequent start and stop of the equipment. Users can flexibly set the range according to their needs, detect the indoor humidity W1 in the warehouse, detect the indoor humidity T3 in the warehouse, obtain the first temperature T1 detected by temperature sensor 1 (T01), and obtain the second temperature T2 detected by temperature sensor 2 (T02).

[0050] By adopting the solution of this embodiment, the first temperature and the second temperature of the inlet water of the wet film humidifier before and after passing through the heat exchanger are adopted, and the evaporation water temperature of the wet film humidifier is flexibly controlled in combination with the indoor temperature and the set temperature of the refrigeration equipment to achieve gradient humidification. Synchronous control of temperature and humidity can be achieved, avoiding the humidification water temperature being too high, which will cause the indoor temperature to rise and affect the cooling effect.

[0051] In one implementation scenario, controlling the evaporation water temperature of the wet film humidifier according to the first temperature, the second temperature, the indoor temperature, and the set temperature includes: determining whether the indoor temperature is greater than the second temperature; if the indoor temperature is greater than the second temperature, determining whether the second temperature is greater than the set temperature; if the second temperature is greater than the set temperature, controlling the inlet water of the wet film humidifier to flow through the condenser of the refrigeration component and the heat exchanger at the same time, and heating the inlet water of the wet film humidifier through the condenser and the heat exchanger.

[0052] When the humidity W1 is less than W, the solenoid valve and flow regulating valve 1 are opened, the wet film humidifier is started, and the wet film humidifier begins to cool the warehouse; when the temperature T3 is greater than T2 and greater than T, the solenoid valve 1 is opened and the flow regulating valve 3 is closed by controlling the pipeline switch of the refrigeration equipment. The flow regulating valves 1 and 2 are opened to the maximum, the refrigeration cycle is started, and the fresh water passes through the condenser and the heat exchanger, and flows into the wet film humidifier after two heat exchanges. The wet film humidifier reaches the maximum humidification efficiency.

[0053] By adopting the solution of this embodiment, when the indoor temperature is high, since the indoor temperature is greater than the second temperature, increasing the evaporation water temperature will not increase the indoor temperature of the room. At the same time, the waste heat of the condenser and the heat exchanger is used to heat the water supply of the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier.

[0054] In one implementation scenario, after determining whether the indoor temperature is greater than the second temperature, it also includes: if the indoor temperature is less than or equal to the second temperature, determining whether the indoor temperature is greater than the first temperature; if the indoor temperature is greater than the first temperature, controlling the inlet water of the wet film humidifier to flow through the condenser, and heating the inlet water of the wet film humidifier through the condenser.

[0055] When T1<T3≤T2, close the flow regulating valve 2, close the hot gas bypass valve, the heat exchanger stops exchanging heat, and the hot water only passes through the condenser for heat exchange once. The wet film humidifier is in medium humidification efficiency.

[0056] By adopting the solution of this embodiment, when the indoor temperature is moderate, between the first temperature and the second temperature, only the waste heat of the condenser is used to heat the water supply of the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier while ensuring the cooling effect.

[0057] In one implementation scenario, after determining whether the indoor temperature is greater than the first temperature, the method further includes: if the indoor temperature is less than or equal to the first temperature, prohibiting heating of water entering the wet-film humidifier.

[0058] When T3≤T1, by controlling the associated switches of the refrigeration equipment, the water inlet of the water pump flows directly into the wet film humidifier without passing through the capillary tube of the condenser. At the same time, the heat absorption pipeline of the heat exchanger is closed, and the opening of the flow control valve 3 is adjusted to control the water temperature at T1. At this time, the temperature is the lowest and the wet film humidifier is in low-efficiency humidification.

[0059] By adopting the solution of this embodiment, when the indoor temperature is low, heating of the water supply to the wet film humidifier is prohibited, thereby preventing the evaporation water temperature of the wet film humidifier from being too high, which may cause the indoor temperature to rise, thereby improving the cooling effect of the refrigeration equipment.

[0060] In another aspect of this embodiment, after detecting the indoor humidity and indoor temperature of the refrigeration equipment, and determining the set temperature and set humidity of the refrigeration equipment, it also includes: judging whether the indoor temperature is greater than the set temperature; if the indoor temperature is greater than the set temperature, starting the compressor of the refrigeration equipment; obtaining a first temperature detected by a first temperature sensor, and obtaining a second temperature detected by a second temperature sensor, wherein the first temperature sensor is installed at the inlet of a heat exchanger and the second temperature sensor is installed at the outlet of the heat exchanger, and the heat exchanger is used to heat the inlet water of the wet film humidifier; judging whether the indoor temperature is greater than the second temperature, and judging whether the indoor humidity is less than the set humidity; if the indoor temperature is greater than the second temperature and the indoor humidity is less than the set humidity, controlling the inlet water of the wet film humidifier to flow through the condenser of the refrigeration component and the heat exchanger at the same time, and heating the inlet water of the wet film humidifier through the condenser and the heat exchanger.

[0061] When T3>T, the compressor is started and the refrigeration cycle is started. When T3>T2 and W1<W, by adjusting the pipeline switch of the refrigeration equipment, adjusting the opening of the flow control valve 2, opening the hot gas bypass valve, the heat exchanger exchanges heat, and the wet film humidifier reaches the maximum humidification efficiency. The wet film humidifier evaporates and absorbs heat. At this time, the system is in the maximum cooling state.

[0062] In this embodiment, the mass flow rate of the water inlet of the wet film humidifier flowing through the heat exchanger (the mass of the fluid passing through the effective cross-section of the closed pipe or open tank per unit time) can also be adjusted. The mass flow rate of the water inlet of the wet film humidifier flowing through the heat exchanger is calculated using the following formula: M2 = [M1*C P (T1-T2)] / (H1-H2); adjusting the opening of the second flow regulating valve (flow regulating valve 2) based on the mass flow, wherein the second flow regulating valve is used to adjust the opening of the hot fluorine gas generated by the compressor entering the heat exchanger, that is, to adjust the heat absorption efficiency of the heat exchanger.

[0063] The temperature detected by temperature sensor 1 (T01) is T1, and the temperature detected by temperature sensor 2 (T02) is T2. The energy added by fresh water through the heat exchanger is Q1, Q1=M1*C P (T1-T2), where M1 is the mass flow rate of water entering the heat exchanger (measured by a flow meter), C P is the specific heat capacity of water. The energy reduced by hot fluorine gas through the heat exchanger is Q2, Q2=M2*(H1-H2), where M2 is the mass flow rate of hot fluorine gas flowing through the heat exchanger, H1 is the enthalpy value of hot fluorine gas before entering the heat exchanger, and H2 is the enthalpy value of hot fluorine gas after entering the heat exchanger. According to the law of conservation of energy, Q1=Q2, so M1*C P (T1-T2)=M2*(H1-H2), the enthalpy difference between system H1 and H2 does not change much (gas type remains unchanged, enthalpy value remains unchanged), so the temperature change is related to the mass flow rate, so T2 temperature is positively correlated with M2; since wet film humidification belongs to low-temperature evaporation humidification, the higher the water temperature, the better the evaporation effect, and the efficiency of the wet film humidifier can be improved by adjusting the opening of the flow control valve 2 to ensure that the wet film humidifier is in the best working state.

[0064] By adopting the solution of this embodiment, when the refrigeration equipment needs to cool and humidify at the same time, under the working condition that the indoor temperature is greater than the second temperature, the water inlet of the wet film humidifier is controlled to flow through the condenser and the heat exchanger for heating at the same time. The heat generated by the compressor condenser is absorbed by the water inlet pipe of the wet film humidifier, which can improve the refrigeration effect of the compressor evaporator. At the same time, the humidification effect of the wet film humidifier can be improved by absorbing heat and increasing the water temperature, so that the refrigeration equipment can be in the optimal cooling state and the optimal humidification state at the same time.

[0065] In one example, after determining whether the indoor temperature is greater than the second temperature, the method further includes: if the indoor temperature is less than or equal to the second temperature, determining whether the indoor temperature is greater than the first temperature; if the indoor temperature is greater than the first temperature, closing the heat exchanger, controlling the inlet water of the wet film humidifier to flow through the condenser, and heating the inlet water of the wet film humidifier through the condenser; if the indoor temperature is less than or equal to the first temperature, prohibiting heating the inlet water of the wet film humidifier.

[0066] When T3≤T2, close flow control valve 2, close the hot gas bypass valve, stop heat exchange in the heat exchanger, and the hot water only passes through the condenser for heat exchange once. The wet film humidifier is at medium humidification efficiency, and the system is in a medium cooling state. When T3≤T1, adjust the opening of flow control valve 3 to control the water temperature at T1. The wet film humidifier is at the lowest humidification efficiency, and the system is in the lowest cooling state. When T3≤T, the compressor stops working, the refrigeration cycle is closed, and the system stops cooling.

[0067] By adopting the solution of this embodiment, the heating state of the water entering the wet-film humidifier is flexibly adjusted according to the relationship between the indoor temperature and the first temperature, thereby achieving gradient cooling while meeting the humidification demand.

[0068] By adopting the solution of this embodiment, the water supply of the wet film humidifier is heated by utilizing the waste heat of the condenser, thereby improving the energy efficiency utilization rate and the humidification efficiency of the wet film humidifier; at the same time, a heat exchanger is added, and the high-temperature gas generated by the compressor is used to further heat the water supply of the wet film humidifier. The inlet water temperature is detected by a temperature sensor, and the opening of the flow control valve is adjusted to ensure that the wet film humidifier is in the best working state; by utilizing the waste heat of the condenser to heat the water supply of the wet film humidifier, the energy efficiency utilization rate is improved and the humidification efficiency of the wet film humidifier is improved.

[0069] Figure 4This is a flowchart of the refrigeration system's workflow in an embodiment of the present invention. The system first detects the set temperature T and set humidity W, then measures the indoor humidity W1 and T3 in real time. The system then obtains the first temperature T1 detected by temperature sensor 1 (T01) and the second temperature T2 detected by temperature sensor 2 (T02). This process includes both a gradient humidification process and a gradient cooling process. The gradient humidification process includes: when the humidity W1 is less than W, the solenoid valve and flow control valve 1 are opened, and the wet film humidifier is turned on to cool the storage; when the temperature T3>T2>T, the solenoid valve 1 is opened, the flow control valve 3 is closed, the flow control valve 1 and the flow control valve are opened to the maximum, the refrigeration cycle is turned on, the fresh water undergoes two heat exchanges, and the wet film humidifier reaches the maximum humidification efficiency; when T1<T3≤T2, the flow control valve 2 is closed, the hot gas bypass valve is closed, the heat exchanger stops heat exchange, and the fresh water only passes through the condenser for one heat exchange, and the wet film humidifier is in medium humidification efficiency; when T3≤T1, the opening of the flow control valve 3 is adjusted to control the water temperature at T1. At this time, the temperature is the lowest, and the wet film humidifier is in low-efficiency humidification. The gradient cooling process includes: when T3>T, the compressor is started and the refrigeration cycle is started. When T3>T2 and W1<W, the opening of the flow control valve 2 is adjusted, the hot gas bypass valve is opened, the heat exchanger performs heat exchange, the wet film humidifier reaches the maximum humidification efficiency, the wet film humidifier evaporates and absorbs heat, and the system is in the maximum cooling state; when T3≤T2, the flow control valve 2 is closed, the hot gas bypass valve is closed, the heat exchanger stops heat exchange, the hot water only passes through the condenser for heat exchange once, the wet film humidifier is in medium humidification efficiency, and the system is in medium cooling state; when T3≤T1, the opening of the flow control valve 3 is adjusted to control the water temperature at T1, the wet film humidifier is in the lowest humidification efficiency, and the system is in the lowest cooling state; when T3≤T, the compressor stops working, the refrigeration cycle is closed, and the system stops cooling.

[0070] By adopting the solution of this embodiment, the energy efficiency is improved by utilizing the waste heat of the condenser to heat the water supply of the wet film humidifier; the high-temperature gas generated by the compressor is used to heat the water supply of the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier.
