In heating operation, outdoor unit (10) The heat exchanger inside (13) functions as an evaporator and heat exchanger (22) inside the indoor unit (20) as condenser It functions. 20 As shown in Figure 2 and Figure 3, the cooling cycle arrangement is west (100) In addition, the outdoor unit (10) is attached to the heat exchanger (13) with a temperature Temperature sensing tert west (60) also ht va. Temperature sensing tert west (60), 25 where the temperature sensing device (60) of the heat exchanger (13) is installed As long as it can sense the temperature of that part, any type of temperature... Temperature sensing tert west (60) example nbr It is a thermostat. Temperature sensing thermostat (60), heat exchanger main It is attached to the end of the lower part of the body (50). First application In this way, the temperature sensing device (60) is located under the protective element (58) 30 It is attached to the right-hand (Y-side) end on the surface. B r In other words, in the first application method, the temperature sensing device is west. 22 (60), inside the end part at the bottom of the main body of the heat exchanger (50) 5 It is attached to the end near the k nc port section (54). As the next step, the defrosting procedure will be explained. Defrosting The operation is to remove the ice formed inside the heat exchanger (13). is carried out. During the heating operation described above, the outdoor 10 heat exchanger (13) which functions as an evaporator (10) the cooler inside the numerous heat transfer pipes (55) Article (40) removes heat from the air in contact with the main body of the heat exchanger (50). Accordingly, the temperature of the main body of the heat exchanger (50) is the heating operation. It falls during this time. In this case, for example, the outdoor unit (10) 15 arranged outdoors, the outdoor temperature is relatively low. when and the outdoor air humidity is relatively low When the temperature is high, the air in contact with the main body of the heat exchanger (50) The moisture inside reaches the dew point temperature, about to condense. and adheres to the surface of the main body of the heat exchanger (50). Main body of the heat exchanger 20 the moisture adhering to the surface of the body (50) temperature is above the freezing point When the temperature is lower, the water solidifies and becomes ice. Application B In the form of, the surface heat transfer pipes of the main body of the heat exchanger (50) (55) surface n, br nc heat transfer fins (56) surface n, k nc heat let the surface of the wings (59a, 59b) and the protective elements (57, 25 58) Surfaces absorb n ht. When the ice is collected on the surface of the main body of the heat exchanger (50), heat the gap between the heat transfer pipes (55) and the heat transfer pipes (55) The gap between the protective elements (57, 58) is for air heat exchanger 30 It is filled in such a way that it will be difficult to pass through the main body (50). This Therefore, coolant flows through numerous heat transfer pipes (55). 23 The heat exchange efficiency between article (40) and the air may decrease and heating 5 The heating capacity in the operation may decrease. Therefore, the heating operation... In a situation where heat continues for a certain period of time, To remove the ice formed on the heat exchanger (13), the heating operation br reverse cycle as defrost operation period as run It is necessary. 10 The water flowing in the circulation path part (30) of the de-icing operation The direction of the coolant (40), circulation during the cooling operation with respect to the direction of the coolant flowing in the path section (30) (40). It is the same. In the defrosting operation, similarly to the cooling operation, the outside 15 heat exchanger (13) inside the space unit (10) as condenser It functions and the heat exchanger (22) inside the indoor unit (20) It functions as an evaporator. In Figure 3, the flowing refrigerant is shown. (40) The direction indicated by the arrowhead is the defrosting operation or cooling. During operation, the direction of flow of the coolant is (40). In Figure 3, 20 As shown, the defrosting operation is according to the first application method and During cooling, from the br nc port section (53) br nc collection coolant that has flowed into the cavity (S1) of the pipe (51) (40), numerous br nc heat transfer pipes on the right side (-Y side) (55a) flows into it. Numerous first heat transfer pipes (55a) flow into it 25 the coolant (40) that has leaked through the heat transfer pipes (55a) in each section to the left (+Y side) and second addition The pipe (52) flows into it. This means that there are many primary heat transfer pipes. Coolant (40) flowing inside pipe (55a), second collection pipe (52) joins inside. 30 24 Coolant (40) that has leaked into the second collection pipe (52), 5 Numerous k nc heat transfer pipes (55b) on the left side (+Y side) It flows inside. As described above, according to the first application method. During the defrosting process, the coolant (40) contains numerous bronch. After passing through the heat transfer tube (55a), numerous secondary heat sources are present. Heat flows into the heat transfer pipe (55b). Numerous secondary heat transfer pipes 10 (55b) Coolant (40) that has flowed into the interior, second heat transfer through the pipes (55b) each br flows to the right side (-Y side). and flows into the inner cavity (S2) of the third collecting pipe (51). This meaning that the water flows inside numerous secondary heat transfer pipes (55b). The coolant (40) combines in the inner space (S2). The inner space (S2) is 15 The coolant that has leaked into the inside (40), from the knc port part (54) It passes through the heat exchanger (13) and flows out. As described above, defrosting and cooling operations. During this time, 20 leaked from the br nc port part (53) into the heat exchanger (13). The coolant (40) is inside a number of heat transfer pipes (55) coolant (40) that has flowed into the heat transfer pipes (55), It flows out of the heat exchanger (13) by passing through the k nc port section (54). During heating operation, the coolant flowing inside the heat exchanger (13) direction of the substance n (40), during the defrosting operation and cooling operation 25 It is opposite in direction. This means that during heating operation, the second port coolant that flowed into the heat exchanger (13) from part (54) (40) flows into numerous heat transfer tubes (55) and numerous heat The coolant (40) that has flowed into the pipe (55), first It flows out of the heat exchanger (13) by passing through the port section (53). 30 Defrosting of the refrigerant n (40) as described above 5 In a situation where it flows as is the case in the operation and cooling operation, a coolant with a high temperature (40), heat exchanger (13) The numerous heat transfer pipes inside (55) flow into it and many Coolant (40) flowing inside a number of heat transfer tubes (55) transfers heat It contacts the main body of the heat exchanger (50) to release it into the air. 10 Therefore, during defrosting, the coolant (40) Thanks to the flow of heat in the same direction in the cooling system, a large number of heats discharged from the coolant (40) flowing inside the let m pipe (55) heat formed on the surface of the main body of the heat exchanger (50) by means of heat It is possible to melt and remove the ice. 15 The controller (17) obtains the temperature sensing device (60) Defrosting based on temperature, cooling cycle, western (100) enables execution. Specifically, for example, temperature sensing. the temperature perceived by the west (60) is predetermined br 20 for a period equal to or longer than that period, brbr nc nc In a situation where the temperature remains lower than the temperature, the controller (17) heat exchanger It is determined that ice has formed on the surface of the main body (50). and cooling cycle arrangement west (100) defrost operation execution It provides. For example, the first temperature is a temperature in the range of -5°C to 0°C. 25 On the other hand, during the defrosting process, the temperature sensing device... The temperature obtained by (60) is equal to the brix nc temperature or In a situation where it is higher than this, the controller (17) heat exchanger 30 of the ice formed on the surface of the main body (50) They determine that the ice has melted and terminate the defrosting operation. The second temperature example is a temperature between 5°C and 10°C. The second... 26 In the application method of temperature, "predetermined temperature" is 5 The corresponding change should be taken into consideration. During the defrosting process, too much Coolant (40) flowing inside a number of heat transfer tubes (55), Coolant material temperature (40) from the port section (53) to the port section It releases heat to melt the ice, so that it falls as it flows into part (54). Therefore, while the ice is still there, to the k nc port part (54) er şen 10 The temperature of the cooling substance (40) is relatively low. On the other hand, ice When completely removed, the heat of the coolant (40) is in the second port part (54) the cooling substance (40) temperature of the ice remains depending on the situation, the temperature will be higher for melting the ice. It is not used. Therefore, the controller (17) is inside the heat exchanger (13) 15 on the downstream side of the flow direction of the coolant (40), side Temperature sensing device on the side near the k nc port (54) By sensing the temperature of the heat exchanger (13) by (60), the ice mold He can perceive that it is gone. According to the first application method, during the defrosting process, the cooler Article (40) contains numerous secondary heat transfer pipes (55b) at the bottom. Before flowing, first at the top there are numerous primary heat transfer pipes. (55a) flows inside. Accordingly, when the defrosting operation is started, much number br nc heat conduction tube (55a) surface, br nc heat conduction 25 its wings (56) are connected to numerous br nc heat transfer tubes (55a). surface of, k nc heat transfer fins (59a) surface and protective Ice adhering to the surface of the elements (57) is first melted. Ice adhering to numerous heat transfer pipes (55a) and similar surfaces 30 In each case, a refrigerant with a relatively high temperature (40), k nc heat transfer pipes (55b) surface, br nc heat transfer 27 its wings (56) are connected to numerous k nc heat transfer pipes (55b) 5 surface of, k nc heat transfer fins (59b) surface and protective The ice adhering to the surface of the elements (58) will be melted one by one. A number of k heat transfer pipes (55b) flow into it. Meanwhile, a large number Ice adhering to the surfaces of the k nc heat transfer pipe (55b) and similar pipes, near the first heat transfer pipes (55a) where the ice has already melted 10 Starting from the top, the temperature gradually decreases and is relatively high. This Therefore, ice forms on the surface of the main body of the heat exchanger (50), until the end of the main body of the heat exchanger (50) on the lower end It shows a tendency to stay put. This means it is moving in a predetermined direction. (in the direction of the key (Z)) numerous heat transfer pipes arranged side by side 15 (55) inside the main body of the heat exchanger (50), the coolant n (40) the part of the port that flows out during the defrosting operation (54), inside the refrigerant (40) during the defrosting operation on the side where it is positioned according to the port part (53) through which it flows (lower (on the side) the end part positioned remains ice until the end 20 It's easy. Here, for example, a large number of secondary heat transfer pipes (55b) flow into it. within the part where the refrigerant (40) is collected, for example the nc port part (54) or circulation path part (30) or similar heat inside 25 with its heat exchanger (13) and flow rate adjustment valve (14) and The perceived temperature k is equal to or higher than the nc temperature t. when the defrosting process ends, the temperature inside the part that stops the defrosting process A situation in which it is perceived will be taken into consideration. In this case, the perceived The temperature is 30, which is formed by the merging of numerous secondary heat transfer pipes (55b). The temperature is based on the temperature of the coolant substance n (40). However, As described above, numerous secondary heat transfer pipes (55b) 28 and similar surfaces, ice adhering to them, starting from the top and in order of priority, 5 Therefore, before all the ice is removed, on the top side... flowing inside the positioned k nc heat transfer pipe (55b) The temperature of the coolant (40) is relatively high and the bottom inside the second heat transfer pipes (55b) positioned on it The temperature of the flowing coolant (40) is relatively low. A result 10 as a result, the temperature of the combined coolant (40) is on the upper side flowing inside the positioned k nc heat transfer pipes (55b) a situation where n is relatively high due to the refrigerant (40). It exists. Accordingly, the perceived temperature is equal to or greater than the k-th temperature. It is higher than this and 15 is located on the lower side Ice formed on the surface of the k nc heat transfer pipes (55b) a situation where the defrosting operation was terminated before the defrosting process was completed It is available. In this case, the k-th is positioned on the bottom of the ice. heat continues to accumulate on the surface of the heat transfer pipes (55b) and The accumulated ice can break and damage the secondary heat transfer pipes (55b). 20 In comparison, the perceived temperature is higher for a period of time than the second. Even if the temperature is equal to or higher than this, the defrosting operation... If carried out, it is possible to suppress the formation of ice. However, this In this case, the defrosting operation time is longer than necessary (25). This tends to cause a malfunction, and the period during which the heating operation is not running increases. Therefore, for the user using the cooling cycle system (100) Comfort decreases. Also, during the defrosting process, the interior unit... (20) The blower fan (23) inside the room blows low temperature air into the room. It is also stopped so as not to send it. Therefore, the refrigerant (40), 30 The liquid does not evaporate inside the heat exchanger (22) of the indoor unit (20). The refrigerant (40) flows into the compressor (12). Therefore, 29 The amount of refrigerant (40) compressed inside the compressor (12) is 5 the pressure increases and there is a possibility that the compressor (12) may be damaged. In addition, the concentration of lubricating oil inside the compressor (12) in the sliding parts inside the compressor (12) A jam may occur. To solve the problem shown above, the current method of application... According to, temperature sensing terminal west (60), heat exchanger main body nn (50) to the end of the bottom side, side port (54) first port It is attached to the end of the side where it is positioned according to part (53). Therefore, coolant flows through numerous heat transfer pipes (55) 15 a heat in which the substance (40) does not combine and the ice tends to remain The temperature of the main body (50) of the heat exchanger is detected by the heat sensing device. It is possible to detect by (60). Accordingly, the controller (17), temperature sensing device based on the temperature obtained by (60) It is advisable to determine that all the ice has been removed by taking the measurements. 20 Therefore, when the de-icing process ends, the ice must remain. It is possible to prevent this. Accordingly, the main body of the heat exchanger (50) the ice continues to accumulate on the lower part It is possible to suppress it. As a result, heat transfer pipes (55) It is possible to prevent damage from the accumulating ice. 25 Furthermore, the defrosting process takes time after all the ice has been removed. Because the defrosting operation can be properly terminated at this point. It is possible to suppress the extension of the execution period. As a result, suppressing the prolongation of the heating system's inability to operate. It is possible and the user using the cooling cycle system (100) 30 It is possible to suppress the decrease in comfort. In addition, the compressor (12) In order to suppress the damage that occurs inside, the compressor (12) inside To suppress the increase in the amount of compression of the coolant (40) 5 It is possible. In addition, the sliding part of the compressor (12) in a way that will prevent the jamming from occurring, compressor (12) the decrease in the concentration of lubricating oil inside It is possible to suppress it. Also, according to the application method, the temperature sensing device is western (60), to the second port part (54) on the lower side of the main body of the heat exchanger (50) It is attached to the nearest end. Heat exchanger main body nn (50) k nc The part closer to the port (54) is where the temperature is about to melt the ice. The cooling level will rise slowly during the defrosting process. The substance (40) is located downstream on the flow side. This Therefore, the end part of the lower side of the main body of the heat exchanger (50) near the port part (54) heat exchanger main body (50) end part By installing the temperature sensing terminal (60) on the main body of the heat exchanger (50) the temperature of the part where the ice tends to stay longer is 20 Temperature sensing can be detected by tert west (60). Therefore, the temperature sensed by the western temperature sense (60) based on the termination of the de-icing process While suppressing the prolongation of the thawing process execution time, the ice It is possible to suppress its persistence. 25 In addition, according to the application method, the main body of the heat exchanger (50), d key direction (Z) connecting heat transfer pipes (55) which are adjacent to each other The first heat transfer fins (56) have. The first heat transfer fins (56), 30 along the left-right direction (Y) where the heat transfer pipes (55) are extended They are grooved fins. Accordingly, the heat exchanger main body (50) inside heat exchange efficiency through the first heat transfer fins (56) 31 It can be improved. In addition, the supply of such first heat transfer fins (56) 5 In the case of ed ld ğ, the first heat transfer fins (56) are in view of Because of this, the temperature between neighboring heat pipes (55) It is difficult to regulate the perception of the inner self (60). The opposite of this is, br nc Application method temperature sensing device (60), heat exchanger main It is attached to the end of the lower part of the body (50). Therefore, the temperature is 10 sensing arrangement west (60) br nc heat transfer wings (56) gr ş m It can be adjusted without doing anything. Also, the temperature sensing device is the first one. To attach heat transfer fins (56) or similar, inside them There is no need to carry out operations such as opening the holes. In addition, according to the application method, the heat transfer pipe (55) d key The directional (Z) dimension of the heat transfer pipe (55) is both left-right directional (Y) and the front where the heat pipe (55) extends in the direction (Z) min- It is smaller than the rear (X) dimension. Heat transfer pipes (55) In a situation where these types of flat pipes are present, in the first application method 20 the gbbr nc collecting tube (51) and k nc collecting the pipe (52) was supplied and numerous heat transfer pipes (55) It's easy to accept the configuration that b rb r is connected to. Therefore, through the heat exchanger (13) the coolant (40) passes through it. The temperature of the outlet port where the ice flows out is 25 during the defrosting operation. Even if it is detected, in the third application form, in the second port section (54) Even if the temperature is detected, the combined coolant (40) The temperature, which is based on its temperature, is perceived as described above, and the point at which all the ice has melted appropriately It is likely that determining this will be difficult. Conversely, the first application is 30 In this way, the temperature sensing device (60) detects heat as described above. Since the heat exchanger is attached to the end part of the main body (50) below, 32 Based on the temperature before combining the coolant (40) 5 to properly determine the point at which all the ice has been removed It is possible. In this way, the heat exchanger of the temperature sensing device (60) obtained by attaching the structure to the end part of the lower part of the main body nn (50). ed len etk nn, çer s ndek ısı transfer m borularının (55) yası borular It can be obtained effectively thanks to the heat exchanger (13) 10 It is probable. In addition, depending on the application method, the heat exchanger (13) has numerous br nc heat transfer pipe (55a) inner part and br nc port part (53) connecting part c, br nc connecting part (51a) and numerous k nc 15 the inner part of the heat transfer pipe (55b) and the inner part of the second port (54) The connecting part k nc connection part (51b) ht va. Defrosting During operation, the coolant (40) transfers numerous primary heat transfers. After flowing through the inside of the pipe (55a), numerous secondary heat transfers The water flows into the pipe (55b). Therefore, as described above, 20 Ice adhering to the surface of the k nc heat transfer pipes (55b), br nc heat let m pipes (55a) melt slower than the ice adhering to the surface It is more likely. Also, among the second heat transfer pipes (55b), k nc heat transfer pipes (55b) br nc heat transfer pipes (55a) If they are positioned that far apart, the ice that adheres to the surface will be 25 slow speed. Therefore, the temperature sensing device (60) heat exchanger main by attaching it to the end of the lower part of the body (50) to keep the ice in place more likely near the k nc heat transfer pipes (55b) It is possible to sense temperature. As a result, temperature sensing Defrost based on the temperature perceived by tert west (60) 30 Thanks to the termination of the operation, the de-icing operation is running. while suppressing the lengthening of the process, it makes the ice stay in place more suitable. 33 It is possible to suppress it. 5 In addition, depending on the application method, the heat exchanger (13) has a large number of heat let m pipe (55) br end part connected br nc collection pipe (51) and the other end of numerous heat transfer pipes (55) It contains the k nc collection pipe (52) to which it is connected. B r nc collection 10 pipe (51) to the connection part (51a) and to the connection part (51b) Accordingly, numerous first heat transfer pipes (55a) and numerous k nc heat transfer tubes (55b) are arranged in a suitable manner in the first collection. It is connected via pipe (51) and k nc collection pipe (52) and Coolant (40) suitable 15 from each heat transfer pipe (55) It can flow in this way. Also, the first collection pipe (51) inside the first by supplying the connecting part (51a) and the second connecting part (51b), br nc port part (53) and k nc port part (54) in the left-right direction (Y) It is also possible to arrange them on the same side. Accordingly, the pipes can be heated. to the port (53) of the heat exchanger (13) and to the port (54) 20 The binding can be easily performed. In addition, according to the application method, the main body of the heat exchanger (50), numerous heat transfer tubes (55) side by side on the bottom regulated protective element (58) and protective element (58) and heat 25 The second heat transfer fins (59b) connecting the heat transfer pipes (55) ht va eder.
