Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, and more specifically, to a refrigeration device. Background Technology
[0002] In related technologies, wet film humidifiers are used in the market for preserving fresh flowers, fruits and vegetables. Since wet film humidification is an air humidification method, it increases the humidity in the air through the contact between water and air.

[0022] Example 1
[0023] This embodiment provides a refrigeration device. Figure 1 This is a structural schematic diagram of a refrigeration device according to an embodiment of the present utility model, as shown below. Figure 1 As shown, the structure includes:
[0024] The system includes a controller 11, a refrigeration component 12, a wet film humidifier 13, and a heat exchanger 14. The water inlet pipe of the wet film humidifier flows through the heat exchanger and then into the wet film humidifier. The heat exchanger is used to absorb the waste heat from the hot fluorine gas generated by the compressor of the refrigeration component and to heat the water in the water inlet pipe of the wet film humidifier.
[0025] By adding a heat exchanger, the high-temperature gas generated by the compressor is used to further heat the water supplied to the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier. This solves the technical problem of low humidification efficiency in related technologies, improving the humidification efficiency of the wet film humidifier while maintaining cooling effect.
[0026] Optionally, the refrigeration assembly further includes a condenser, through which the water inlet pipe of the wet film humidifier flows into the heat exchanger, and the condenser is used to heat the water in the water inlet pipe of the wet film humidifier.
[0027] By using the waste heat of the condenser to heat the water supply of the wet film humidifier, the energy efficiency is improved, and the humidification efficiency of the wet film humidifier is also improved.
[0028] Optionally, the heat exchanger includes an absorber component and a release component connected to each other. The absorber component is used to absorb the waste heat from the hot fluorine gas generated by the compressor of the refrigeration component. The release component is used to heat the water in the water inlet pipe of the wet film humidifier. The absorber component includes a flow regulating valve, which is used to regulate the mass flow rate of the hot fluorine gas flowing through the absorber component.
[0029] A heat exchanger that can simultaneously absorb and release heat has been developed, improving the waste heat utilization rate of the compressor.
[0030] The controller in this embodiment includes: a detection module for detecting the indoor humidity and indoor temperature of the refrigeration equipment, and determining the set temperature and set humidity of the refrigeration equipment, wherein the refrigeration equipment includes a refrigeration component and a wet film humidifier; a first judgment module for judging whether the indoor humidity is less than the set humidity; and a first control module for starting the wet film humidifier if the indoor humidity is less than the set humidity, and controlling 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.
[0031] In this embodiment, indoor humidity and indoor temperature refer to the real-time temperature and humidity in the working area of the refrigeration equipment, such as inside a room or warehouse. The refrigeration equipment simultaneously performs refrigeration and humidification. The refrigeration components of the refrigeration equipment are used for refrigeration, and the wet film humidifier is used for humidification. The refrigeration components include a compressor, condenser, evaporator, etc.
[0032] By heating the water in a wet film humidifier to increase the evaporation temperature, the rate at which water evaporates from the wet film surface into the air can be increased, thereby improving humidification efficiency.
[0033] Figure 2This is a piping diagram of a refrigeration device in an embodiment of this utility model. The refrigeration device includes a compressor 01; a gas-liquid separator 02; a cooler 03; a dryer 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 1V02; a solenoid valve 2V03; a flow regulating valve 1V04; a flow regulating valve 2V05; a hot gas bypass valve V06; a flow regulating valve 3V07; a temperature sensor 1T01, corresponding to the first temperature sensor; and a temperature sensor 2T02, corresponding to the second temperature sensor.
[0034] When the refrigeration equipment is working, water pump 07 sends fresh water into condenser 06, where it exchanges heat with the high-temperature, high-pressure gas generated by compressor 01. The fresh water is heated for the first time, filtered by filter 09, and then reaches heat exchanger 10 through flow regulating valve 1V04, where it exchanges heat with the high-temperature, high-pressure gas generated by compressor 01 for the second time. It then enters wet film humidifier 08 for humidification under the control of solenoid valve. The high-temperature, high-pressure gas generated by compressor 01 enters oil-gas separator 05 through pipeline. Part of the high-temperature, high-pressure gas enters condenser 06 for heat exchange, becoming a medium-temperature, high-pressure liquid. After passing through dryer filter 04, it becomes a low-temperature, low-pressure liquid through electronic expansion valve 01. It then enters air cooler 03 for evaporative cooling, becoming a low-temperature, low-pressure gas, and returns to compressor 01 through gas-liquid separator 02. The other part of the high-temperature, high-pressure gas reaches heat exchanger 10 through flow regulating valve 205, exchanges heat with fresh water, and then returns to compressor 01 through hot gas bypass valve 06.
[0035] In one embodiment of this example, the first control module includes: an acquisition unit, configured to acquire a first temperature detected by a first temperature sensor and 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 a heat exchanger, and the heat exchanger is used to heat the inlet water of the wet film humidifier; and a control unit, configured to control the evaporation water temperature of the wet film humidifier according to the first temperature, the second temperature, the indoor temperature, and the set temperature.
[0036] The first temperature is the water temperature before heating by the heat exchanger, and the second temperature is the water temperature after heating by the heat exchanger. The system sets the operating temperature T and operating humidity W of the refrigeration equipment, where T and W are range values to avoid frequent start-ups and shutdowns of the equipment. Users can flexibly set these ranges according to their needs. The system detects the indoor humidity W1 and T3 inside the refrigeration chamber, acquires the first temperature T1 detected by temperature sensor 1 T01, and acquires the second temperature T2 detected by temperature sensor 2 T02.
[0037] The solution in this embodiment uses the first and second temperatures of the water entering the wet film humidifier before and after passing through the heat exchanger, combined with the indoor temperature and set temperature of the refrigeration equipment, to flexibly control the evaporation water temperature of the wet film humidifier, thereby achieving gradient humidification. This allows for synchronous control of temperature and humidity, preventing excessively high humidification water temperature from causing an increase in indoor temperature and affecting the cooling effect.
[0038] In one implementation scenario, the control unit includes: a first judgment subunit, used to judge whether the indoor temperature is greater than the second temperature; a second judgment subunit, used to judge whether the second temperature is greater than the set temperature if the indoor temperature is greater than the second temperature; and a first control subunit, used to control the water entering the wet film humidifier to flow through the condenser and the heat exchanger of the refrigeration component simultaneously if the second temperature is greater than the set temperature, and to heat the water entering the wet film humidifier through the condenser and the heat exchanger.
[0039] When the humidity W1 < W, the solenoid valve and flow regulating valve 1 are opened to start the wet film humidifier, which begins to cool the warehouse. When the temperature T3 > T2 > 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 their maximum, the refrigeration cycle is started, and fresh water flows into the wet film humidifier after passing through the condenser and the heat exchanger and undergoing two heat exchanges. The wet film humidifier reaches its maximum humidification efficiency.
[0040] In 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 raise the room temperature. At the same time, the waste heat of the condenser and heat exchanger is used to heat the water supply of the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier.
[0041] In one implementation scenario, the control unit further includes: a third judgment subunit, configured to, after the second judgment subunit determines whether the indoor temperature is greater than the second temperature, determine whether the indoor temperature is greater than the first temperature if the indoor temperature is less than or equal to the second temperature; and a second control subunit, configured to, if the indoor temperature is greater than the first temperature, control the water inlet of the wet film humidifier to flow through the condenser and heat the water inlet of the wet film humidifier through the condenser.
[0042] When T1 < T3 ≤ T2, the flow regulating valve 2 is closed, the hot gas bypass valve is closed, the heat exchanger stops exchanging heat, the water only passes through the condenser once for heat exchange, and the wet film humidifier is at a medium humidification efficiency.
[0043] By adopting the solution of this embodiment, when the indoor temperature is moderate and 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.
[0044] In one implementation scenario, the control unit further includes a third control subunit, configured to prohibit heating of the water entering the wet film humidifier if the indoor temperature is less than or equal to the first temperature after the third judgment subunit determines whether the indoor temperature is greater than the first temperature.
[0045] When T3≤T1, by controlling the associated switch of the refrigeration equipment, the water pump inlet water flows directly into the wet film humidifier without passing through the capillary tube of the condenser. At the same time, the heat exchanger's heat absorption pipe is closed, and the opening of the flow regulating valve 3 is adjusted to control the water temperature of T1. At this time, the temperature is the lowest, and the wet film humidifier is in low-efficiency humidification.
[0046] By adopting the solution of this embodiment, heating the water supply to the wet film humidifier is prohibited when the indoor temperature is low, so as to prevent the evaporation water temperature of the wet film humidifier from being too high and causing the indoor temperature to rise, thereby improving the cooling effect of the refrigeration equipment.
[0047] In another aspect of this embodiment, the controller further includes: a second judgment module, configured to determine whether the indoor temperature is greater than the set temperature after the detection module detects the indoor humidity and indoor temperature of the refrigeration equipment and determines the set temperature and set humidity of the refrigeration equipment; a start module, configured to start the compressor of the refrigeration equipment if the indoor temperature is greater than the set temperature; an acquisition module, configured to acquire a first temperature detected by a first temperature sensor and a second temperature detected by a second temperature sensor, wherein the first temperature sensor is installed at the inlet of the 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 water entering the wet film humidifier; a third judgment module, configured to determine whether the indoor temperature is greater than the second temperature and whether the indoor humidity is less than the set humidity; and a second control module, configured to control the water entering the wet film humidifier to flow simultaneously through the condenser of the refrigeration component and the heat exchanger if the indoor temperature is greater than the second temperature and the indoor humidity is less than the set humidity, and to heat the water entering the wet film humidifier through the condenser and the heat exchanger.
[0048] When T3 > T, the compressor is started, and the refrigeration cycle is initiated. When T3 > T2 and W1 < W, the flow regulating valve 2 is adjusted by adjusting the pipeline switch of the refrigeration equipment, and the hot gas bypass valve is opened. The heat exchanger exchanges heat, and the wet film humidifier reaches its maximum humidification efficiency. The wet film humidifier absorbs heat through evaporation, and the system is in the maximum cooling state at this time.
[0049] In this embodiment, the mass flow rate of the water entering the wet film humidifier through the heat exchanger can also be adjusted. This refers to the fluid mass passing through the effective cross-section of a closed pipe or open tank per unit time. The mass flow rate of the water entering the wet film humidifier through the heat exchanger is calculated using the following formula: M2 = [M1 * C P [T1-T2] / H1-H2; Based on the mass flow rate, adjust the opening of the second flow regulating valve 2, 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.
[0050] Temperature sensor 1T01 detects temperature T1, temperature sensor 2T02 detects temperature T2, and fresh water gains energy Q1 after passing through the heat exchanger, where Q1 = M1 * C. P T1-T2, where M1 is the mass flow rate of the water entering the heat exchanger, measured by a flow meter, and C... P Let M2 be the specific heat capacity of water. The energy reduction of the hot fluorine gas as it passes through the heat exchanger is Q2, where Q2 = M2 * H1 - H2, and M2 is the mass flow rate of the hot fluorine gas through the heat exchanger, H1 is the enthalpy of the hot fluorine gas before entering the heat exchanger, and H2 is the enthalpy of the hot fluorine gas after entering the heat exchanger. According to the law of conservation of energy, Q1 = Q2, therefore M1 * C P T1-T2=M2*H1-H2. The enthalpy difference between H1 and H2 in the system does not change much, the gas type remains unchanged, and the enthalpy value remains unchanged. Therefore, the temperature change is related to the mass flow rate, so the temperature T2 is positively correlated with M2. Since wet film humidification is a low-temperature evaporative humidification, the higher the water temperature, the better the evaporation effect. The efficiency of the wet film humidifier can be improved by adjusting the opening of the flow regulating valve 2 to ensure that the wet film humidifier is in the best working state.
[0051] In this embodiment, when the refrigeration equipment needs to both cool and humidify, and the indoor temperature is higher than the second temperature, the water entering the wet film humidifier is heated by simultaneously flowing through the condenser and heat exchanger. By absorbing the heat generated by the compressor condenser through the water inlet pipe of the wet film humidifier, the cooling effect of the compressor evaporator can be improved. At the same time, increasing the heat absorption and raising the water temperature can improve the humidification effect of the wet film humidifier, so that the refrigeration equipment can be in the optimal cooling and humidification state at the same time.
[0052] In one example, the controller further includes: a fourth judgment module, configured to, after the third judgment module determines whether the indoor temperature is greater than the second temperature, determine whether the indoor temperature is greater than the first temperature if the indoor temperature is less than or equal to the second temperature; and a third control module, configured to, if the indoor temperature is greater than the first temperature, shut down the heat exchanger, control the water inlet of the wet film humidifier to flow through the condenser, and heat the water inlet of the wet film humidifier through the condenser; and if the indoor temperature is less than or equal to the first temperature, prohibit heating the water inlet of the wet film humidifier.
[0053] When T3 ≤ T2, close flow regulating valve 2 and hot gas bypass valve. The heat exchanger stops heat exchange, and the water only passes through the condenser once for heat exchange. 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 regulating valve 3 to control the water temperature at T1. The wet film humidifier is at minimum humidification efficiency, and the system is in a minimum cooling state. When T3 ≤ T, the compressor stops working, the refrigeration cycle is shut off, and the system stops cooling.
[0054] The solution in this embodiment flexibly adjusts the heating state of the water entering the wet film humidifier according to the relationship between the indoor temperature and the first temperature, so as to achieve gradient cooling while meeting the humidification requirements.
[0055] The solution in this embodiment improves energy efficiency and humidification performance by utilizing waste heat from the condenser to heat the water supply to the wet film humidifier. Additionally, a heat exchanger is added to further heat the water supply using high-temperature gas generated by the compressor. A temperature sensor detects the inlet water temperature and adjusts the flow control valve opening to ensure the wet film humidifier operates at its optimal state. By utilizing waste heat from the condenser to heat the water supply, both energy efficiency and humidification performance are improved.
[0056] Figure 3This is a flowchart of the controller's operation in this embodiment of the invention. First, the set temperature T and set humidity W of the refrigeration equipment are detected. Then, the indoor humidity W1 and T3 inside the refrigeration unit are detected in real time. The first temperature T1 detected by temperature sensor 1T01 and the second temperature T2 detected by temperature sensor 2T02 are obtained. The process includes a gradient humidification process and a gradient cooling process. The gradient humidification process includes: when humidity W1 < W, the solenoid valve and flow regulating valve 1 are opened, and the wet film humidifier starts to cool the room; when temperature T3 > T2 > T, the solenoid valve 1 is opened and the flow regulating valve 3 is closed, the flow regulating valve 1 and the flow regulating valve are opened to the maximum, the refrigeration cycle starts, the fresh water undergoes two heat exchanges, and the wet film humidifier reaches its maximum humidification efficiency; when T1 < T3 ≤ T2, the flow regulating valve 2 is closed and the hot gas bypass valve is closed, the heat exchanger stops heat exchange, the fresh water only undergoes one heat exchange through the condenser, and the wet film humidifier is at a medium humidification efficiency; when T3 ≤ T1, the opening of the flow regulating valve 3 is adjusted to control the water temperature T1, at which point the temperature is the lowest, and the wet film humidifier is at a low-efficiency humidification. The gradient cooling process includes: when T3 > T, the compressor is started, and the refrigeration cycle is initiated; when T3 > T2 and W1 < W, the opening of flow regulating valve 2 is adjusted, the hot gas bypass valve is opened, the heat exchanger exchanges heat, the wet film humidifier reaches its maximum humidification efficiency, and the wet film humidifier absorbs heat through evaporation, at which point the system is in the maximum cooling state; when T3 ≤ T2, flow regulating valve 2 is closed, the hot gas bypass valve is closed, the heat exchanger stops exchanging heat, the water only passes through the condenser once for heat exchange, the wet film humidifier is at a medium humidification efficiency, at which point the system is in a medium cooling state; when T3 ≤ T1, the opening of flow regulating valve 3 is adjusted to control the water temperature at T1, the wet film humidifier is at its minimum humidification efficiency, at which point the system is in the minimum cooling state; when T3 ≤ T, the compressor stops working, the refrigeration cycle is shut down, and the system stops cooling.
[0057] The solution in this embodiment improves energy efficiency by using the waste heat of the condenser to heat the water supply of the wet film humidifier; and improves the humidification efficiency of the wet film humidifier by using the high-temperature gas generated by the compressor to heat the water supply of the wet film humidifier.
