請再配合參考圖1所示，若本發明係進行一冷氣運轉模式，壓縮機10將冷媒壓縮後吐出。冷媒係經過四方閥11與第五管體24進入室外熱交換器14。該壓縮機10所吐出之冷媒係為一高溫高壓之冷媒。 Referring to FIG. 1 again, if the present invention performs a cool air operation mode, the compressor 10 compresses the refrigerant and discharges it. The refrigerant enters the outdoor heat exchanger 14 through the square valve 11 and the fifth pipe body 24. The refrigerant discharged from the compressor 10 is a high temperature and high pressure refrigerant.
冷媒於室外熱交換器14進行一散熱的動作，以形成一低溫冷媒，該低溫冷媒會經由第六管體25分別進入第一膨脹閥130與第二膨脹閥131。該低溫冷媒係為一低溫高壓之冷媒。 The refrigerant heats the outdoor heat exchanger 14 to form a low-temperature refrigerant that enters the first expansion valve 130 and the second expansion valve 131 via the sixth pipe body 25, respectively. The low temperature refrigerant is a low temperature and high pressure refrigerant.
該低溫冷媒會於第二膨脹閥131中進行膨脹的動作，以形成 一低溫低壓之冷媒。該低溫低壓之低溫冷媒會經由第一管體20進入室內熱交換器12，以進行一吸熱的動作，藉此將一冷氣提供給一室內，經過吸熱的低溫低壓係形成為一高溫低壓冷媒。 The low temperature refrigerant is expanded in the second expansion valve 131 to form A low temperature low pressure refrigerant. The low-temperature low-pressure low-temperature refrigerant enters the indoor heat exchanger 12 via the first pipe body 20 to perform an endothermic action, thereby supplying a cold air to a room, and the low-temperature low-pressure system through the heat absorption is formed into a high-temperature low-pressure refrigerant.
該高溫冷媒係由第二管體21流入四方閥11，再由第三管體22流入壓縮機10中，以再進行壓縮冷媒之動作，以形成一高溫高壓之冷媒。 The high-temperature refrigerant flows into the square valve 11 from the second pipe body 21, and then flows into the compressor 10 from the third pipe body 22 to further compress the refrigerant to form a high-temperature high-pressure refrigerant.
假若本發明之裝置因負載變化或室外環境變化，而處於一種不平衡的狀態時，前述之第一膨脹閥130就會開啟，以供低溫高壓冷媒進行膨脹，經過膨脹的低溫低壓冷媒會由第七管體26流入第二管體21，並與來自室內熱交換器12的高溫低壓冷媒混合，以形成一中溫低壓冷媒，該中溫低壓冷媒係流入四方閥11，再由由第三管體22流入壓縮機10中，以再進行壓縮冷媒之動作。藉由兩種溫度與壓力的冷媒進行混合，以到該裝置呈現一平衡的狀態。該中溫低壓之低壓係大於該高溫低壓之低壓。第一膨脹閥130的開度係取決於該裝置所需達到平衡的程度，若該裝置所欲達到之平衡程度越大時，則第一膨脹閥130的開度越大。反之，假若該裝置所欲達到之平衡程度越小時，則第一膨脹閥130的開度越小。 If the device of the present invention is in an unbalanced state due to load changes or changes in the outdoor environment, the aforementioned first expansion valve 130 is opened for the low temperature and high pressure refrigerant to expand, and the expanded low temperature and low pressure refrigerant will be The seven pipe body 26 flows into the second pipe body 21 and is mixed with the high temperature and low pressure refrigerant from the indoor heat exchanger 12 to form a medium temperature low pressure refrigerant, which flows into the square valve 11 and then from the third pipe. The body 22 flows into the compressor 10 to perform the operation of compressing the refrigerant. The two devices are mixed with a temperature of pressure to bring the device to a balanced state. The low temperature of the medium temperature and low pressure is greater than the low pressure of the high temperature and low pressure. The degree of opening of the first expansion valve 130 depends on the degree to which the device needs to be balanced, and the greater the degree of balance desired by the device, the greater the opening of the first expansion valve 130. On the other hand, if the degree of balance desired by the device is small, the opening degree of the first expansion valve 130 is smaller.
若第二感知器16與室內溫度感知器18感測出室內應進行一除濕的動作時，第三膨脹閥132就會開啟，一冷媒會由第八管體27流入第五管體24，位於第八管體27的冷媒會被壓縮機10提昇至一特定溫度，以形成一高溫高壓冷媒，再進入第三膨脹閥132中膨脹，以形成一高溫低壓之冷媒，位於第八管體27之高溫高壓之冷媒的高溫係大於位於第五管體24之高溫高壓之冷媒的高溫。該高溫低壓之冷媒會流入第一管體20，並與來自第二膨脹閥131的低溫低壓之冷媒進行混合，以形成一中溫低壓冷媒，再進入室內熱交換器12中，以進行一熱交換，故可使室內溫度能夠維持於穩定，並能達到除濕的效果。來自第三膨脹閥132之高溫低壓之冷媒的低壓係大於來自第二膨脹閥131的低溫低壓之冷媒的低壓。該第三膨脹閥132的開度係取決於該裝置所需達到除濕的程 度，若該裝置所欲達到之除濕程度越大時，則第三膨脹閥132的開度越大。反之，假若該裝置所欲達到之除濕程度越小時，則第三膨脹閥132的開度越小。 If the second sensor 16 and the indoor temperature sensor 18 sense that the room should perform a dehumidification operation, the third expansion valve 132 is opened, and a refrigerant flows from the eighth pipe body 27 into the fifth pipe body 24, which is located. The refrigerant of the eighth pipe body 27 is lifted by the compressor 10 to a specific temperature to form a high temperature and high pressure refrigerant, and then expanded into the third expansion valve 132 to form a high temperature and low pressure refrigerant, which is located in the eighth pipe body 27. The high temperature and high pressure refrigerant has a higher temperature than the high temperature and high pressure refrigerant of the fifth tube body 24. The high temperature and low pressure refrigerant flows into the first pipe body 20 and is mixed with the low temperature and low pressure refrigerant from the second expansion valve 131 to form a medium temperature low pressure refrigerant, and then enters the indoor heat exchanger 12 to perform a heat. Exchange, so that the indoor temperature can be maintained stable, and can achieve the effect of dehumidification. The low pressure of the high temperature and low pressure refrigerant from the third expansion valve 132 is greater than the low pressure of the low temperature and low pressure refrigerant from the second expansion valve 131. The opening degree of the third expansion valve 132 depends on the degree of dehumidification required by the device. The degree of opening of the third expansion valve 132 is greater if the degree of dehumidification desired by the device is greater. On the other hand, if the degree of dehumidification desired by the apparatus is small, the opening degree of the third expansion valve 132 is smaller.
請配合參考圖2所示，若本發明進行一暖氣模式運轉，壓縮機10係將一高溫高壓之冷媒吐出。該高溫高壓之冷媒係經過第四管體23進入四方閥11，再由第二管體21進入室內熱交換器12，以進行一放熱的動作，藉此提供一暖氣給室內。經過放熱的該高溫高壓之冷媒係形成為一低溫高壓之冷媒。 Referring to FIG. 2, if the present invention performs a heating mode operation, the compressor 10 discharges a high temperature and high pressure refrigerant. The high-temperature high-pressure refrigerant enters the square valve 11 through the fourth pipe body 23, and then enters the indoor heat exchanger 12 from the second pipe body 21 to perform a heat release operation, thereby providing a heating to the room. The exothermic high temperature and high pressure refrigerant is formed into a low temperature and high pressure refrigerant.
該低溫高壓之冷媒會由第一管體20流入第二膨脹閥131與第三膨脹閥132。該低溫高壓之冷媒係於第二膨脹閥131進行一膨脹的動作，以形成一低溫低壓之冷媒，該低溫低溫冷媒係由第六管體25流入室外熱交換器14，以進行一吸熱的動作，以形成為一高溫低壓冷媒，再由第五管體24流入四方閥11，並由第三管體22流入壓縮機10中，以進行一壓縮冷媒的動作，以形成一高溫高壓之冷媒。 The low-temperature high-pressure refrigerant flows into the second expansion valve 131 and the third expansion valve 132 from the first pipe body 20. The low-temperature high-pressure refrigerant is subjected to an expansion operation by the second expansion valve 131 to form a low-temperature low-pressure refrigerant that flows from the sixth pipe body 25 into the outdoor heat exchanger 14 to perform an endothermic action. In order to form a high temperature and low pressure refrigerant, the fifth pipe body 24 flows into the square valve 11 and flows into the compressor 10 from the third pipe body 22 to perform a compression refrigerant operation to form a high temperature and high pressure refrigerant.
若本發明欲進行一平衡時，第三膨脹閥132就會開啟，來自第一管體20的低溫高壓之冷媒就會進入第三膨脹閥132，以進行一膨脹的動作，以形成一低溫低壓之冷媒。來自第三膨脹閥132之低溫低壓之冷媒的低壓係大於來自第一膨脹閥131之低溫低壓之冷媒的低壓。 If the present invention is to perform an equilibrium, the third expansion valve 132 is opened, and the low-temperature high-pressure refrigerant from the first pipe body 20 enters the third expansion valve 132 to perform an expansion operation to form a low-temperature low pressure. The refrigerant. The low pressure of the low temperature and low pressure refrigerant from the third expansion valve 132 is greater than the low pressure of the low temperature and low pressure refrigerant from the first expansion valve 131.
來自第三膨脹閥132之低溫低壓之冷媒會由第八管體27進入第五管體24。位於第八管體27的低溫冷媒會被壓縮機10提昇至一特定的溫度，以形成為一高溫低壓之冷媒。該高溫低壓之冷媒之高溫係低於位於第五管體24之高溫低壓之冷媒的高溫。 The low temperature and low pressure refrigerant from the third expansion valve 132 enters the fifth pipe body 24 from the eighth pipe body 27. The low temperature refrigerant located in the eighth pipe body 27 is lifted by the compressor 10 to a specific temperature to form a high temperature and low pressure refrigerant. The high temperature and low pressure refrigerant has a higher temperature than the high temperature and low pressure refrigerant of the fifth tube body 24.
因室外熱交換器14可能處於一種結霜的情況，故原先進入室外交換器14的低溫低壓之冷媒係無法吸熱，而形成高溫低壓之冷媒，反而釋出更多的熱能，並形成更為低溫的低溫低壓之冷媒，若該低溫低壓之冷媒直接流入壓縮機10中，則有可能造成液壓縮的情況。 Because the outdoor heat exchanger 14 may be in a frosting condition, the low temperature and low pressure refrigerant originally entering the outdoor exchanger 14 cannot absorb heat, and the high temperature and low pressure refrigerant is formed, which in turn releases more heat energy and forms a lower temperature. The low-temperature low-pressure refrigerant may cause liquid compression if the low-temperature low-pressure refrigerant directly flows into the compressor 10.
所以來自第八管體27的高溫低壓之冷媒與上述之低溫低壓之 冷媒係於第五管體24中混合，以形成為一中溫低壓之冷媒，該高溫低壓之冷媒的低壓係大於該中溫低壓之冷媒的低壓。該中溫低壓之冷媒係經由四方閥11與第三管體22，再流入壓縮機10中，以避免該冷媒發生液壓縮的現象，並能使本發明達到一平衡的效果。 Therefore, the high temperature and low pressure refrigerant from the eighth pipe body 27 and the above low temperature and low pressure The refrigerant is mixed in the fifth pipe body 24 to form a medium temperature and low pressure refrigerant, and the low pressure of the high temperature and low pressure refrigerant is greater than the low pressure of the medium temperature and low pressure refrigerant. The medium-temperature low-pressure refrigerant flows into the compressor 10 via the square valve 11 and the third pipe body 22 to prevent the refrigerant from being compressed, and the present invention achieves a balanced effect.
該第三膨脹閥132的開度係取決於該裝置所需達到平衡的程度，若該裝置所欲達到之平衡程度越大時，則第三膨脹閥132的開度越大。反之，假若該裝置所欲達到之平衡程度越小時，則第三膨脹閥132的開度越小。 The opening degree of the third expansion valve 132 depends on the degree to which the device needs to reach equilibrium. If the degree of balance desired by the device is greater, the opening degree of the third expansion valve 132 is larger. On the other hand, if the degree of balance desired by the device is small, the opening degree of the third expansion valve 132 is smaller.
若室外溫度感知器17與第一感知器15感測出應進行一除霜動作時，第一膨脹閥130就會開啟，位於第二管體21中之高溫高壓冷媒係由第七管體26流入第一膨脹閥130中，以進行一膨漲動作，而形成一高溫低壓之冷媒。， If the outdoor temperature sensor 17 and the first sensor 15 sense that a defrosting action should be performed, the first expansion valve 130 is opened, and the high temperature and high pressure refrigerant located in the second pipe body 21 is the seventh pipe body 26 The first expansion valve 130 flows into the first expansion valve 130 to perform a swelling operation to form a high temperature and low pressure refrigerant. ,
該高溫低壓之冷媒流入第六管體25中，而與來自第二膨脹閥131之低溫低壓之冷媒混合後，以形成一中溫低壓冷媒，再流入室外熱交換器14，以進行一除霜的動作，並同時進行一吸熱的動作，以形成一高溫低壓之冷媒，來自第一膨脹閥130之高溫低壓之冷媒的高溫係大於外熱交換器14之高溫低壓之冷媒的高溫。如無法形成該高溫低壓之冷媒則如上述之平衡效果，來自室外熱交換器14的低溫冷媒係與來自第八管體27的高溫冷媒於第五管體24中進行混合，以形成一中溫低壓之冷媒，如上之暖氣模式運轉所述，該高溫冷媒或該中溫冷媒係經由第五管體24流入四方閥11，並由第三管體22流入壓縮機10中。 The high temperature and low pressure refrigerant flows into the sixth pipe body 25, and is mixed with the low temperature and low pressure refrigerant from the second expansion valve 131 to form a medium temperature low pressure refrigerant, and then flows into the outdoor heat exchanger 14 to perform a defrosting. The action is performed simultaneously with an endothermic action to form a high temperature and low pressure refrigerant. The high temperature and low pressure refrigerant from the first expansion valve 130 has a higher temperature than the high temperature and low pressure refrigerant of the outer heat exchanger 14. If the high temperature and low pressure refrigerant cannot be formed, the low temperature refrigerant from the outdoor heat exchanger 14 and the high temperature refrigerant from the eighth pipe body 27 are mixed in the fifth pipe body 24 to form a medium temperature. In the low-pressure refrigerant, as described above in the heating mode operation, the high-temperature refrigerant or the intermediate-temperature refrigerant flows into the square valve 11 through the fifth pipe body 24, and flows into the compressor 10 from the third pipe body 22.
請配合圖3所示，其為本發明之具除濕與除霜功能之裝置之第二實施例。於本實施例中，壓縮機10、四方閥11、室內熱交換器12、冷媒控流機構13、室外熱交換器14、第一感知器15、第二感知器16、室外溫度感知器17、室內溫度感知器18、第一管體20、第二管體21、第三管體22、第四管體23、第五管體24、第六管體25、第七管體26與第八管體27的配置方式係如上述之第一實施例，故元件符號係沿用上一實施例。 Please refer to FIG. 3, which is a second embodiment of the device with dehumidification and defrosting function of the present invention. In the present embodiment, the compressor 10, the square valve 11, the indoor heat exchanger 12, the refrigerant flow control mechanism 13, the outdoor heat exchanger 14, the first sensor 15, the second sensor 16, the outdoor temperature sensor 17, Indoor temperature sensor 18, first tube body 20, second tube body 21, third tube body 22, fourth tube body 23, fifth tube body 24, sixth tube body 25, seventh tube body 26 and eighth The arrangement of the tubular body 27 is as in the first embodiment described above, so that the component symbols follow the previous embodiment.
於本實施例中，一閥體28係設於第八管體27，該閥體28係分別耦接第八管體27的一第一位置270與一第二位置271。該第一位置270係位於第三膨脹閥132與壓縮機10之間。該第二位置271係位於壓縮機10與第五管體24之間。該閥體28為一單向閥，故僅允許冷媒遵循單一方向流動。 In the present embodiment, a valve body 28 is coupled to the eighth tubular body 27, and the valve body 28 is coupled to a first position 270 and a second position 271 of the eighth tubular body 27, respectively. The first position 270 is located between the third expansion valve 132 and the compressor 10. The second position 271 is located between the compressor 10 and the fifth tubular body 24. The valve body 28 is a one-way valve, so that only the refrigerant is allowed to flow in a single direction.
若於冷氣運轉模式中進行除濕動作時，假設欲降低除濕效果，則閥體28就會開啟，因流體具有由高壓流向低壓的特性，故高溫冷媒會自動由該第二位置271流向該第一位置270，而不會通過繞設於壓縮機10的第八管體27，而使該高溫冷媒不會藉由壓縮機10再提昇至一特定溫度，藉此降低除濕的效果。 If the dehumidification operation is performed in the air-conditioning operation mode, it is assumed that the dehumidification effect is to be lowered, the valve body 28 is opened, and since the fluid has a characteristic of flowing from a high pressure to a low pressure, the high-temperature refrigerant automatically flows from the second position 271 to the first. At position 270, the high temperature refrigerant is not lifted by the compressor 10 to a specific temperature by winding the eighth pipe body 27 of the compressor 10, thereby reducing the effect of dehumidification.
同理，請配合參考圖4所示，因閥體28為一單向閥，若於暖氣模式運轉模式中進行一平衡動作時，來自第三膨脹閥132的低溫冷媒無法通過閥體28，而僅能於第八管體27中流動，並被壓縮機所加熱，以形成一高溫冷媒，該高溫冷媒再流入第五管體24中。 Similarly, please refer to FIG. 4, since the valve body 28 is a one-way valve, if a balancing operation is performed in the heating mode operation mode, the low-temperature refrigerant from the third expansion valve 132 cannot pass through the valve body 28, and It can only flow in the eighth pipe body 27 and is heated by the compressor to form a high temperature refrigerant which flows into the fifth pipe body 24.

若於冷氣運轉模式，當第一溫度小於第二溫度時，第二膨脹閥131就會開啟，第二膨脹閥131的開度係取決於第一溫度與第二溫度的差值，若第一溫度減去第二溫度的數值越小時，則該開度就會越大，以增強冷氣效果。 If in the cold air operation mode, when the first temperature is lower than the second temperature, the second expansion valve 131 is opened, and the opening degree of the second expansion valve 131 is determined by the difference between the first temperature and the second temperature, if the first The smaller the value of the temperature minus the second temperature, the larger the opening will be to enhance the cooling effect.

As shown in the figure, curve A indicates that the present invention is in a state of providing heating, and the outdoor temperature is about 7 ° C or more. After about several minutes, the curve A starts to appear flat, that is, the heating supply system tends to In the steady state, if the running time is longer, the flatness of the curve A will be more obvious.
曲線B係表示室外溫度約界於7℃至0℃之間，本發明係進行一除霜運轉，並調整冷段回路與熱段回路。該冷段回路係上述之低溫冷媒所流經的路線。該熱段回路係上述之高溫冷媒所流經的路線。約於數分鐘後，曲線B與貼近於曲線A，並呈現一平坦狀，即除霜與暖氣提供係趨於一穩定狀態。 Curve B indicates that the outdoor temperature is between about 7 ° C and 0 ° C. The present invention performs a defrosting operation and adjusts the cold section circuit and the hot section circuit. The cold section circuit is a route through which the above-mentioned low temperature refrigerant flows. The hot section circuit is a route through which the high temperature refrigerant described above flows. After about a few minutes, the curve B is close to the curve A and presents a flat shape, that is, the defrosting and heating supply tends to be in a stable state.
若要更進一步論述曲線B，請再配合參考圖2所示，一高溫高壓之冷媒係流入室內熱交換器12，並經過一放熱過程，以形成一低溫高壓之冷媒。該低溫高壓之冷媒係由第一管體20流入冷媒控流機構13中，並進行一膨脹過程，以形成一低溫低壓之冷媒。 To further discuss curve B, please refer to FIG. 2 again, a high temperature and high pressure refrigerant flows into the indoor heat exchanger 12 and undergoes a heat release process to form a low temperature and high pressure refrigerant. The low-temperature high-pressure refrigerant flows into the refrigerant flow control mechanism 13 from the first pipe body 20, and performs an expansion process to form a low-temperature low-pressure refrigerant.
