Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a solar-assisted temperature regulation air conditioning system. Background Art

[0002] Existing air conditioning systems mainly include an indoor unit and an outdoor unit. An expansion valve and an evaporator are provided in the indoor unit, and a compressor and a condenser are provided in the outdoor unit.

[0003] During refrigeration operation, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gas state and sends it to the condenser for cooling. After cooling, the refrigerant condenses into a medium-temperature and high-pressure liquid refrigerant and enters the drying and filtering component for filtering. The medium-temperature liquid refrigerant is throttled and depressurized by the expansion valve into a low-temperature and low-pressure gas-liquid mixture, which vaporizes by absorbing heat from the air in the evaporator, turns into a gas state, and then returns to the compressor to continue compression, and continues to cycle for refrigeration; during heating operation, the functions of the indoor evaporator and the outdoor condenser are interchanged through pipelines, and the compressed condenser of the refrigeration system is used to heat the indoor air.

[0004] During the heating process of existing air conditioners, the outdoor condenser is used to evaporate the refrigerant and needs to absorb heat from the environment. When the outdoor ambient temperature is not lower than 7°C, the air conditioner can achieve an ideal heating effect during heating operation under rated conditions. However, when the outdoor ambient temperature is lower than 7°C, the heating effect of the air conditioner decreases. The lower the temperature, the greater the decrease in the heating effect. In winter, the outdoor temperature often drops below 7°C, and the heat absorption efficiency of the refrigerant during vaporization is very low, which not only causes the heating effect of the air conditioner to decrease, but also increases the power consumption; secondly, during the refrigeration process, most of the outdoor condensers use heat dissipation fins and air-cooling methods for heat dissipation, and this heat dissipation method has the problem of low heat dissipation efficiency.

Detailed implementation mode

[0019] Combined with Figures 1 to 9 The solar-assisted temperature regulation air-conditioning system of the present invention will be further described.

[0020] A solar-assisted temperature regulation air-conditioning system, characterized in that: it includes an air conditioner 2 and an auxiliary temperature regulation device 1, the air conditioner 2 includes an outdoor unit 21 and an indoor unit 22, and the auxiliary temperature regulation device 1 includes a temperature regulator 12, a solar collector 11 and a control pipeline 14.

[0021] The temperature regulator 12 is arranged on the rear air inlet side of the outdoor unit 21 of the air conditioner 2, and includes a water tank 123 with an upper opening, a heat exchange component 122 arranged on the upper opening of the water tank 123, and a spraying device 121 arranged above the heat exchange component 122. The spraying device 121 is a group of spray heads, which are connected to the water tank 123 through a pipeline 4. A spraying water pump 3 is arranged on the pipeline 4 to pump the water in the water tank 123 to the spray heads, and then the water is evenly sprayed onto the heat exchange component 122 by the spray heads; the water storage tank 111 of the solar collector 11 is connected to the water tank 123 through a control pipeline 14 and can circulate with the water in the water tank 123.

[0022] In use, the temperature regulator 12 is fixed to the air conditioner mounting bracket by bolting and is located inside the outdoor unit 21 of the air conditioner 2, i.e., on the air inlet side, so that the air flow entering the outdoor unit 21 of the air conditioner 2 first passes through the temperature regulator 12 for temperature regulation. When the air conditioner 2 is cooling, the water storage tank 111 of the solar collector 11 is disconnected from the water tank 123, and the water in the water tank 123 is at room temperature. The spray water pump 3 pumps the water to the spray device 121 and then sprays it onto the heat exchange component 122, so that the air flow passing through the temperature regulator 12 exchanges heat with the heat exchange component 122. After the air flow passes through the heat exchange component 122 and is cooled, it enters the outdoor unit 21 of the air conditioner 2 to exchange heat with the condenser 211 in the outdoor unit 21, significantly improving the condensation effect of the condenser 211 and reducing the condensation energy consumption at the same time. When the air conditioner 2 is heating, the water storage tank 111 of the solar collector 11 is connected to the water tank 123, so that the water heated by the solar collector 11 in the water storage tank 111 circulates to the water tank 123. The spray device 121 sprays the hot water in the water tank 123 onto the heat exchange component 122, so that the air flow passing through the temperature regulator 12 exchanges heat with the heat exchange component 122. After the air flow is heated, it enters the condenser 211 in the outdoor unit 21 of the air conditioner 2 to exchange heat, enabling the air conditioner to operate in heating mode under rated conditions, significantly increasing the evaporation temperature of the refrigerant in the condenser 211, increasing the heating capacity of the air conditioner, and reducing the energy consumption.

[0023] The control pipeline 14 includes a water inlet pipeline 141, a water return pipeline 142, a circulation water pump 143, a one-way valve 144 and a water tank temperature sensor.

[0024] The water inlet pipeline 141 is arranged between the water outlet of the water storage tank 111 of the solar collector 11 and the water inlet of the water tank 123, and the water return pipeline 142 is arranged between the water outlet of the water tank 123 and the water inlet of the water storage tank 111 of the solar collector 11, enabling the water between the water tank 123 and the water storage tank 111 to flow. The circulation water pump 143 and the one-way valve 144 are arranged on the water return pipeline 142 to drive the water in the water storage tank 111 and the water in the water tank 123 to circulate unidirectionally.

[0025] The water tank temperature sensor is disposed in the water tank 123 and electrically connected to the controller of the air-conditioning system. The controller is electrically connected to the circulation water pump 143. When the air conditioner 2 operates for heating and the water temperature in the water tank 123 is lower than the set value, the circulation water pump 143 starts to circulate the water in the water tank 123 to the water storage tank 111 for heating by solar energy. In this embodiment, it is set to be heated to above 50°C. At the same time, the hot water in the water storage tank 111 is supplemented into the water tank 123 to heat the heat exchange component 122. Through the induction of the water tank temperature sensor, when the water temperature in the water tank exceeds 25°C, the circulation can be stopped, so that the water temperature in the water tank is maintained at 15-25°C, reducing the working time of the circulation water pump and lowering the energy consumption. During actual use, the water temperature in the water tank can be controlled according to the actual ambient temperature, the amount of hot water in the heat preservation water tank, and the hot water production amount of the solar collector. A float valve 131 is provided at the water inlet of the water tank 123. When the water level in the water tank 123 is lower than a certain level, the float valve 131 opens to supplement hot water.

[0026] The auxiliary temperature adjustment device 1 further includes a heat preservation water tank 13. The heat preservation water tank 13 is disposed on the water inlet pipeline 141 and communicated with the water tank 123. The heat preservation water tank 13 can realize the constant-temperature storage of hot water, and can also provide hot water for auxiliary heating on rainy days or at night; it can also store a large amount of hot water to be used by multiple air-conditioning systems simultaneously, and can also meet other hot water usage requirements.

[0027] The heat preservation water tank 13 is also directly communicated with the return water pipeline 142 through a valve body. The valve body is a first electric three-way valve 145. The first electric three-way valve 145 is electrically connected to the controller, and its three valve ports are respectively connected to the water inlet end of the circulation water pump 143, the water outlet end of the one-way valve 144, and the water outlet of the heat preservation water tank 13. Under this pipeline structure, according to actual usage requirements, by controlling the first electric three-way valve 145, the circulation between the solar collector 11, the water storage tank 111 and the heat preservation water tank 13 can be realized, and the flow between the water storage tank 111, the water tank 123 and the heat preservation water tank 13 can also be realized, significantly improving the flexibility of the entire air-conditioning system.

[0028] A water tank temperature sensor is provided in the heat preservation water tank 13, and the water tank temperature sensor is electrically connected to the circulating water pump 143 and the first electric three-way valve 145. That is, the water tank temperature sensor is electrically connected to the controller, and sends the temperature signal to the controller, and then the controller controls the operation of the circulating water pump 143 and the first electric three-way valve 145. When the water temperature in the heat preservation water tank 13 is lower than the set value, such as 50 °C, through the first electric three-way valve 145, the heat preservation water tank 13 is directly connected to the circulating water pump 143, and the circulating water pump 143 pumps the water in the heat preservation water tank 13 into the storage water tank 111. At the same time, the hot water in the storage water tank 111 is replenished into the heat preservation water tank through the water inlet of the heat preservation water tank 13, so as to circulate to make the water temperature in the heat preservation water tank 13 not lower than 50 °C for use. When the water temperature in the water tank 123 is lower than the set value, the first electric three-way valve 145 connects the one-way valve 144 and the circulating water pump 143, so that the water circulates among the heat preservation water tank 13, the water tank 123 and the storage water tank 111. That is, the circulating water pump 143 drives the water flow in the water tank to enter the storage water tank 111 after passing through the one-way valve, the liquid level of the water tank drops, and the hot water in the heat preservation water tank 13 is replenished into the water tank through the float valve on the water inlet of the water tank until the water temperature sensor in the water tank senses that the water temperature reaches the set value.

[0029] A float valve 131 is also connected to the heat preservation water tank. The float valve 131 is connected to the tap water pipe. When the water level in the heat preservation water tank is lower than the replenishment water level of the float valve, tap water is replenished into the heat preservation water tank through the float valve.

[0030] The heat exchange component 122 includes a mounting frame 1222 mounted above the water tank 123 by clamping or bolt mounting and a wet film 1221 provided in the mounting frame 1222. There is a flow channel between the wet films 1221 for the air flow to flow from the side away from the outdoor unit 21 of the air conditioner 2 to the side facing the outdoor unit 21 of the air conditioner 2. The spray water pump 3 sends the hot water at 15-25 °C in the water tank to the top spray device 121, and the spray device evenly distributes it on the wet film. The wet film infiltrated with hot water exchanges heat with the air, and can heat the air at 2 °C to about 7 °C. The air at 7 °C then passes through the condenser in the outdoor unit of the air conditioner to ensure that the air conditioner operates for heating under near-rated conditions, so as to achieve a higher energy efficiency ratio, reduce energy consumption, and at the same time ensure that the heating capacity of the air conditioner meets the indoor heating demand.

[0031] By setting the heat exchange area of the wet film 1221 and the length of the flow channel, the passing air can be heated to 10-15 °C, greatly increasing the heating capacity of the air conditioner and obtaining a higher energy efficiency ratio. The heat exchange area of the wet film 1221 and the flow channel structure are prior arts, and only the dimensions need to be adjusted in this embodiment.

[0032] Taking the energy efficiency ratio of refrigerant R410A at evaporation temperatures of -8°C and -3°C as an example, under normal operating conditions, the evaporation temperature of the refrigerant is about 10°C lower than the ambient air temperature. Therefore, when the evaporation temperature of refrigerant R410A is -8°C and -3°C, the inlet air temperatures of the outdoor unit 21 of the air conditioner 2 are 2°C and 7°C respectively: Set operating conditions -8.0 / 48.0 °C Compressor ZP83KFE-TFD Refrigerating capacity, kW 10.25 Compressor power, kW 5.59 COP 1.83 Current at 380V, A 10.83 Suction mass flow rate, g / s 63.70 Heating capacity, kW 15.85 Isentropic efficiency, % 58.08 When the evaporation temperature of refrigerant R410A in the outdoor unit condenser is -8°C, the inlet air temperature of the outdoor unit 21 of the air conditioner 2 is 2°C, the air conditioner operates in heating mode, the heating capacity of the air conditioner unit is 15.85kW, the compressor power is 5.59kW, and the heating energy efficiency ratio is 2.83; Set operating conditions -3.0 / 48.0 °C Compressor ZP83KFE-TFD Refrigerating capacity, kW 14.90 Compressor power, kW 5.63 COP 2.65 Current at 380V, A 10.84 Suction mass flow rate, g / s 90.50 Heating capacity, kW 20.50 Isentropic efficiency, % 66.30 When the evaporation temperature of refrigerant R410A in the outdoor unit condenser is -3°C, the inlet air temperature of the outdoor unit 21 of the air conditioner 2 is 7°C, the air conditioner operates in heating mode, the heating capacity of the air conditioner unit is 20.5kW, the compressor power is 5.63kW, and the heating energy efficiency ratio is 3.64.

[0033] By comparison, when the auxiliary temperature regulating device 1 is not working, driven by the outdoor unit fan of the air conditioner, the 2°C air directly passes through the outdoor unit condenser, and the refrigerant in the outdoor unit condenser evaporates and absorbs heat. At this time, the evaporation temperature of the refrigerant is about -8°C, and the heating energy efficiency ratio is 2.83; when the auxiliary temperature regulating device 1 is working, driven by the outdoor unit fan of the air conditioner, the 2°C air is heated to 7°C after heat exchange with the temperature regulator 12, and then passes through the outdoor unit condenser. The refrigerant in the outdoor unit condenser evaporates and absorbs heat. At this time, the evaporation temperature of the refrigerant is about -3°C, and the heating energy efficiency ratio is 3.64, and the heating energy efficiency ratio is significantly improved. According to the working characteristics of the common refrigerant R410A, compared with the rated working condition, the energy efficiency ratio is reduced by nearly 25%, and at the same time, the heating capacity of the air conditioner will also decrease significantly.

[0034] The auxiliary temperature regulating device 1 further includes a photovoltaic auxiliary heating device 5, and the photovoltaic auxiliary heating device 5 includes a photovoltaic panel power generation component 51, a storage battery 52 and a heating component 53. The photovoltaic panel power generation component 51 is connected to the storage battery 52 to charge the storage battery 52. The heating component 53 is arranged in the heat preservation water tank 13 and is connected to the storage battery 52. When the air-conditioning system is used for heating in the daytime with sufficient sunlight, the solar collector 11 can be used to heat the water in the heat preservation water tank 13, and the heating component 53 does not need to work. When the air-conditioning system is used for heating at night or in rainy weather, the solar collector 11 cannot generate hot water by solar energy, and when the hot water stored in the heat preservation water tank 13 cannot meet the hot water consumption of the temperature regulator 12, the heating component 53 powered by solar energy can be started to heat the water in the heat preservation water tank 13 to the set value, so that the temperature regulator 12 can be used for heating the air for a long time at night or in rainy weather. The heating component 53 is arranged in the heat preservation water tank 13 instead of in the solar collector 11, so that the present invention has two independent heating devices to heat the water in the heat preservation box. When any component in the solar collector 11 or the photovoltaic auxiliary heating device 5 fails, it will not affect the use of the temperature regulator 12 for heating the air. Secondly, when the water temperature in the heat preservation water tank 13 is lower than the set value at night or in rainy weather, the heating component 53 can be directly started for heating, without transferring the water in the heat preservation water tank 13 to the solar collector 11 for heating, which can not only avoid heat loss during the water flow process, but also save the power consumption required for the operation of the circulation water pump 143.

[0035] A second electric three-way valve 6 is further arranged on the return water pipeline 142, and the second electric three-way valve 6 is also connected to the controller of the air-conditioning system. The three valve ports of the second electric three-way valve 6 are respectively connected to the water inlet of the solar collector 11, the water outlet of the circulation water pump 143 and the water inlet of the heat preservation water tank 13. When the temperature regulator 12 is used for heating at night or in rainy weather, since the solar collector 11 cannot generate hot water, in this case, the second electric three-way valve 6 conducts the circulation water pump and the heat preservation water tank 13, and at the same time disconnects the circulation water pump from the water inlet of the solar collector 11, and the circulation water pump directly passes the water flowing out of the water tank into the heat preservation water tank 13, shortening the water flow path and reducing heat loss. As the water in the water tank circulates to the heat preservation water tank 13 for multiple times, when the water temperature in the heat preservation water tank 13 is lower than the set value, the heating component 53 is started for heating.

[0036] The heating component 53 includes an air compressor 533, a heating pipe 531, and a throttle valve 532. The heating pipe 531 is arranged in a coil shape in the heat preservation water tank 13. The air inlet end and the air outlet end of the heating pipe 531 are respectively connected to the air compressor 533 and the throttle valve 532, and the air compressor 533 is connected to the storage battery 52. During operation, the storage battery 52 supplies power to the air compressor 533. The air compressor 533 compresses the air and sends it into the heating pipe 531 through a pipeline. After being compressed, the air temperature rises and enters the heating pipe 531, where it exchanges heat with the water in the heat preservation water tank 13, and finally is discharged after passing through the throttle valve 532, achieving a heating effect on the water in the heat preservation water tank 13.

[0037] During specific use, the heating component 53 can also directly use an electric heating wire or a carbon fiber heating cloth.

[0038] In the temperature regulator 12 structure, it includes a frame body 124, and the frame body 124 is a hollow quadrilateral frame structure. There is a front opening, i.e., an air inlet 1241, on the front side of the frame body 124, and a rear opening, i.e., an air outlet 1242, on the rear side. At the same time, the frame body 124 forms a groove structure in the up, down, left, and right directions corresponding to the front opening and the rear opening. The groove structure at the bottom is the water tank 123. The four edges of the mounting frame 1222 of the heat exchange component 122 are respectively sealed and clamped on the notches of the four groove structures, so that the front and rear sides of the heat exchange component 122 respectively correspond to the air inlet 1241 and the air outlet of the frame body 124. The spray heads in the spray device 121 are arranged in the groove structure at the top of the frame body 124, and the pipeline 4 in the spray device 121 is arranged in the groove structure on the left or right side of the frame body 124, so that when the water in the water tank is pumped to the spray device 121, it is all inside the frame body 124, reducing heat loss.

[0039] A heat preservation layer, such as a foaming layer, is provided on the outer surface of the frame body 124, and a surface layer is provided on the outside of the heat preservation layer to insulate the frame body 124 and reduce heat loss.

[0040] A filtering component 125 is provided at the air inlet of the temperature regulator 12. Specifically, the filtering component 125 is clamped or bolted to the air inlet of the frame body 124. The filtering component 125 is an air filter element, and the filter element covers the entire air inlet of the frame body 124, so that the air entering the frame body 124 and contacting the heat exchange component 122 is filtered by the filter element to improve the cleanliness of the wet film 1221 and the water.

[0041] During the low-temperature heating process of this air-conditioning system, in order to increase the contact heat exchange time between the gas heated by the temperature regulator 12 and the condenser in the outdoor unit 21, the auxiliary temperature regulation device 1 is also provided with a seal 126, a baffle 7, and a grille cover 8.

[0042] The seal 126 is disposed between the air outlet 1242 of the temperature regulator 12 and the rear air inlet of the outdoor unit 21. Specifically, a rubber seal 126 with a corrugated structure is fixed on the air outlet 1242 of the frame body 124 by means of embedding or bonding. The shape of the seal 126 is adapted to the shape of the air outlet 1242 of the temperature regulator 12, which is a quadrilateral, and encloses the air outlet 1242 of the frame body 124. When the temperature regulator 12 is assembled to the back of the air conditioner outdoor unit, one end of the seal 126 facing away from the frame body 124 closely adheres to the outer side wall of the outdoor unit, and at the same time encloses the rear air inlet on the side of the outdoor unit facing the frame body 124, avoiding the problem that the gas heated by the temperature regulator 12 leaks from the gap between the frame body 124 and the outdoor unit, and reducing heat loss.

[0043] The baffle 7 is detachably disposed on the side wall of the temperature regulator 12 and extends to the side of the outdoor unit to block the side air inlet 212 on the side wall of the outdoor unit. Specifically, there are two connecting plates 71 on the side of the baffle 7 facing the temperature regulator 12. The two connecting plates 71 are fixed on the side wall of the frame body of the temperature regulator 12 by bolts. A rubber sealing layer is provided on the side of the baffle 7 facing the outdoor unit. The rubber sealing layer corresponds to the side air inlet 212 of the outdoor unit to seal the side air inlet 212, avoiding the outdoor ambient temperature air flow entering the outdoor unit through the side air inlet 212 during the heating process and affecting the heat exchange between the heated gas and the condenser.

[0044] The grille cover 8 is arranged on the air outlet of the outdoor unit. A pull rod assembly for pressing the grille cover 8 against the air outlet of the outdoor unit is provided between the grille cover 8 and the temperature regulator 12. The grille cover 8 can increase the resistance of the gas flowing out of the outdoor unit, and at the same time can reduce the gas flow rate, so that the heated gas can be located in the outdoor unit for a longer time, increasing the heat exchange time with the condenser, making full use of the temperature of the heated gas, and at the same time increasing the evaporation effect of the refrigerant in the condenser.

[0045] There are two groups of the pull rod assemblies, which are respectively located at the top and bottom of the temperature regulator 12, and each includes a positioning seat 92, an extension rod 9 and a pressing rod 10.

[0046] Two L-shaped positioning seats 92 are fixed at the top and bottom positions of the frame body of the temperature regulator 12 by bolts or welding and have through holes. The first end of the extension rod 9 is fitted in the through hole and is fitted with a nut 91, and the second end extends to the front side of the outdoor unit. The pressing rod 10 is integrally formed at the second end of the extension rod 9 and is perpendicular to the extension rod 9. One end of the pressing rod 10 facing away from the extension rod 9 presses against the stepped edge position 81 of the grille cover 8. After turning the nut 91, the extension rod 9 can be pulled towards the back side of the outdoor unit, so that the pressing rod 10 presses the grille cover 8 against the air outlet of the outdoor unit.

[0047] To improve the stability of the pressing rod 10 pressing on the grille cover 8, an arc-shaped plate 101 is further provided at one end of the pressing rod 10 facing the grille cover 8. The extending trajectory of the arc-shaped plate 101 is the same as the circular arc trajectory of the edge position 81 of the grille cover 8, so that the entire arc-shaped plate 101 can press against the edge position of the grille cover 8, increasing the contact area and thus improving the stability of the grille cover 8.

[0048] The baffle 7 and the grille cover 8 are generally used when the temperature is below zero. When the ambient temperature is above 7°C, the baffle 7 and the grille cover 8 can be disassembled, and the refrigerant in the condenser can be effectively evaporated through the ambient temperature. It should be noted that the baffle 7 and the grille cover 8 are suitable for use when the user is likely to touch the outdoor unit of the air conditioner.

[0049] In the above air-conditioning system, without changing the structure of the outdoor unit itself, the auxiliary temperature regulating device can be used in cooperation with the outdoor unit of the air conditioner, which is convenient for the user to install according to actual usage needs. For users who already have an installed air conditioner, they only need to install the auxiliary temperature regulating device, which has the characteristics of high usage flexibility.
