In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0063] In some embodiments of the present application, an air-cooled hot and cold water unit is provided, comprising:

[0064] A refrigerant circulation path formed by connecting the compressor, the heat exchanger 810 and the shell-and-tube heat exchanger;

[0065] And a water circulation flow path is formed inside the shell and tube heat exchanger, and the water flowing through the shell and tube heat exchanger can be output after heat exchange with the refrigerant flowing through the shell and tube heat exchanger;

[0066] In some embodiments of the present application, a four-way valve is arranged between the compressor and the heat exchanger 810, and the four-way valve is respectively connected to the compressor and the heat exchanger 810. The heat exchanger 810 is connected to the shell and tube heat exchanger through a refrigerant pipeline, and is used to transport the refrigerant flowing through the heat exchanger 810 for heat exchange to the shell and tube heat exchanger.

[0067] The shell and tube heat exchanger includes an outer shell and tube heat exchange tube group and an inner shell and tube heat exchange tube group. When connected, the outer shell and tube heat exchange tube group is connected to the heat exchanger 810 through a refrigerant pipeline;

[0068] A water circulation flow path for water circulation is formed inside the inner shell-and-tube heat exchange tube group.

[0069] A water inlet and a water outlet are arranged on the inner sleeve heat exchange tube group.

[0070] The external water flows into the inner shell-and-tube heat exchange tube group from the water inlet and then is discharged from the water outlet.

[0071] The shell and tube heat exchanger is an intermediate transfer heat exchanger 810, which is used to achieve heat exchange between the refrigerant flowing out of the condenser and the water entering the shell and tube heat exchanger.

[0072] For the convenience of explanation, this embodiment is described by taking the outlet water obtained by the air-cooled hot water unit as cold water as an example.

[0073] The high-temperature and high-pressure gas discharged from the compressor flows out through the four-way valve and flows into the heat exchanger 810 connected to the four-way valve, enters the heat exchanger to exchange heat with the air and release heat, then flows out of the heat exchanger 810 and enters the outer shell heat exchange tube group of the shell-and-tube heat exchanger;

[0074] At this time, water with higher temperature is input into the inner shell and tube heat exchange tube group from the water inlet, and the refrigerant flowing through the outer shell and tube heat exchange tube group exchanges heat with the water in the inner shell and tube heat exchange tube group inside the shell and tube heat exchanger. The refrigerant absorbs the heat of the water in the inner shell and tube heat exchange tube group and cools the water so that the cold water discharged from the water outlet is the cold water required by the user.

[0075] On the contrary, when the air-cooled hot water unit needs to obtain hot water from the water outlet, the flow direction of the refrigerant is opposite to the flow direction of obtaining cold water.

[0076] The high-temperature and high-pressure gas discharged from the compressor passes through the gas-liquid separator and the oil separator return oil and enters the four-way valve, and then enters the outer shell heat exchange tube group from the four-way valve line to exchange heat with the water flowing through the inner shell heat exchange tube group. The refrigerant entering the outer shell heat exchange tube group releases heat, and the water flowing through the inner shell heat exchange tube group absorbs heat, so that the water is heated up so that the water flowing out of the water outlet is hot water.

[0077] Heat is exchanged between water and the refrigerant in the compressor unit to obtain water at the required temperature for user use.

[0078] When the refrigerant flows through the heat exchanger 810 for heat exchange, frost will form on the heat exchanger 810, and then defrost water will be produced.

[0079] The water receiving tray 100 is used to receive condensed water from the heat exchanger 810 and to support the heat exchanger 810, and includes:

[0080] A protrusion 110 is formed in the middle of the water receiving tray 100. The protrusion 110 is a protrusion. The protrusion 110 is protruded upward and is used to support and carry the heat exchanger 810.

[0081] and a water receiving portion 120 arranged around the protruding portion 110 for receiving defrosting water dropped from the heat exchanger 810;

[0082] The top surface of the protrusion 110 is arranged higher than the water receiving portion 120. On the one hand, it can ensure that the defrost water falling from the heat exchanger 810 will fall to the lower water receiving portion 120. On the other hand, it can also ensure that the defrost water in the water receiving portion 120 will not penetrate into the bottom position of the heat exchanger 810 arranged on the protrusion 110, causing corrosion to the bottom of the heat exchanger 810 and affecting the performance of the heat exchanger 810.

[0083] The water receiving portion 120 is arranged at a circumferential position of the protrusion 110, and the heat exchanger 810 is arranged on the protrusion 110, so that the defrost water dropped from the heat exchanger 810 arranged on the protrusion 110 can just fall into the water receiving portion 120 at the circumferential position, so as to better receive the defrost water and prevent the defrost water from falling out.

[0084] The main heating component 200 is arranged in the water receiving portion 120 and is used to heat the defrost water in the water receiving portion 120 .

[0085] In some embodiments of the present application, the main heating component 200 is a heating belt, which is arranged to fit tightly on the bottom surface of the water receiving portion 120. The power of the heating belt needs to be large enough. The high temperature generated by the heating belt can ensure that the defrost water of the unit flows smoothly in a high humidity and low temperature environment, thereby preventing the defrost water from freezing in the water receiving tray 100.

[0086] In some embodiments of the present application, the main heating component 200 is a main heating tube, which is bent and arranged along the circumference of the protrusion 110 and generates heat by electrical heating.

[0087] In some embodiments, the main heating component 200 is a heating sheet or a heating wire.

[0088] When the air-cooled hot and cold water unit is in operation, the refrigerant passes through the heat exchanger 810 for heat exchange. After long-term heat exchange use, especially after absorbing heat and cooling for a period of time, frost will condense on the surface of the heat exchanger 810. The frost condensed on the surface of the heat exchanger 810 may melt to form defrosting water and drip down.

[0089] In an environment with high humidity and low temperature, the defrost water dropped from the heat exchanger 810 will directly condense into ice in the water receiving tray 100 under the influence of the ambient temperature and cannot be discharged to the outside of the entire device.

[0090] If the defrost water condenses into ice and cannot be discharged in time, it will affect the heat exchange performance of the heat exchanger 810 and the components inside the entire unit. To avoid the above problems, the air-cooled hot and cold water unit correspondingly sets a main heating component 200 at the water receiving part 120 used to serve as the main water receiving part 120.

[0091] The main heating component 200 arranged in the water receiving portion 120 can be used to heat the water in the water receiving portion 120 to transfer heat, thereby preventing the defrost water in the water receiving portion 120 from condensing into ice when the ambient temperature is low, thereby ensuring that the defrost water in the water receiving tray 100 can be discharged normally.

[0092] The water receiving portion 120 is arranged around the circumference of the protrusion 110, and the main heating component 200 arranged inside the water receiving portion 120 is also arranged around the protrusion 110 to achieve uniform temperature heating of the water flow in the water receiving portion 120, ensuring that no area of ​​the water receiving portion 120 will freeze, ensuring that the defrost water in the water receiving tray 100 can be completely discharged to the outside of the unit, and ensuring the drainage effect of the defrost water.

[0093] In some embodiments of the present application, the air-cooled hot and cold water unit includes: a drainage pipe group 300, which is used to discharge the defrosted water in the water receiving tray 100 to the outside, is connected to the water receiving tray 100, and is extended downward along the height direction of the unit;

[0094] The drainage pipe group 300 is composed of a plurality of drainage pipes 310 . The drainage pipes 310 are connected to the bottom of the water receiving tray 100 , so as to discharge the defrosted water in the water receiving tray 100 to the outside of the unit.

[0095] The drainage pipe group 300 is arranged to extend downward along the height direction of the unit, so as to ensure that the defrost water entering the water receiving pipe group is discharged smoothly and accelerated under the action of gravity.

[0096] The auxiliary heating element 400 has one end fixed on the water receiving tray 100 and another end extending into the drain pipe assembly 300 , and is used to heat the defrost water flowing through the drain pipe 310 .

[0097] In some embodiments of the present application, the auxiliary heating element 400 is an auxiliary heating belt, one end of which is assembled and fixed on the water receiving tray 100, and the other end extends into the interior of the drain pipe group 300. When the auxiliary heating belt is working, it can generate heat. The heat generated by the auxiliary heating belt is used to heat the defrost water to prevent the defrost water from freezing inside the drain pipe group 300 and blocking the defrost water flow channel, thereby ensuring that the defrost water is discharged normally.

[0098] In some embodiments of the present application, the auxiliary heating element 400 is an auxiliary heating tube or an auxiliary heating wire.

[0099] The auxiliary heating element 400 is arranged to extend along the length direction of the drain pipe group 300, and its length is at least 2 / 3 of the length of the drain pipe group 300 to ensure that the length of the auxiliary heating element 400 extending into the drain pipe group 300 is long enough to ensure the heating effect on the flowing defrost water.

[0100] In some embodiments of the present application, the drain pipe 310 is made of stainless steel to ensure the safety of the drain pipe 310 in the high temperature environment generated by the auxiliary heating element 400. If PV or PE material is used, the high temperature generated by the auxiliary heating element 400 will damage the drain pipe 310, reducing or even damaging the drainage performance of the unit.

[0101] In some embodiments of the present application, the drain pipe 310 is in the form of a bellows, which has strong deformability and can be bent inside the unit, which can effectively avoid the components of the unit and ensure the safety of the components. The end of the drain pipe 310 is outside the unit to ensure that the defrost water is discharged from the inside of the unit.

[0102] In some embodiments of the present application, the water receiving tray 100 includes: long sides, arranged along the length direction of the water receiving tray 100, and the first long sides are provided with two, arranged oppositely;

[0103] There are two short sides arranged opposite to each other, and the two short sides are connected between the ends of the two long sides.

[0105] Bending plate groups are arranged on both sides of the protruding portion 110 , and the water receiving portion 120 is formed by the bending plate groups.

[0106] In some embodiments, the bending plate group includes: a first bending plate formed on the side of the protrusion 110, a second bending plate connected to the first bending plate, and a third bending plate and a blocking plate connected to the second bending plate.

[0107] The second bending plate is formed by bending from the end of the first bending plate, the third bending plate is formed by bending from the second bending plate, the third bending plate is arranged opposite to the first bending plate, and the second bending plate is connected between the first bending plate and the third bending plate.

[0108] Sealing plates are arranged at both ends of the first bending plate, the second bending plate and the third bending plate.

[0109] The water receiving portion 120 is formed by surrounding the first bending plate, the second bending plate, the third bending plate and the blocking plate.

[0110] The water receiving portion 120 includes two water receiving grooves 121 , which are arranged on both sides of the water receiving tray 100 and extend along the length direction of the water receiving tray 100 .

[0111] The two water receiving grooves 121 are symmetrically arranged at both sides of the protruding portion 110 .

[0112] The two water receiving grooves 121 are both formed by bending plate groups arranged on both sides of the protrusion 110. The water receiving grooves 121 are surrounded by the bending plate groups to form a closed groove body, ensuring that the defrost water located therein will not flow out from the two ends of the water receiving grooves 121.

[0113] There are two sets of drain pipe groups 300, and the two sets of drain pipe groups 300 are respectively arranged corresponding to the positions of the two water receiving tanks 121. The drain pipe groups 300 are arranged in a manner corresponding to the water receiving tanks 121, so that each water receiving tank 121 can be provided with a drain pipe group 300 adapted thereto, so as to ensure that the defrost water in each water receiving tank 121 can be guided and discharged to the outside of the unit.

[0114] In some embodiments of the present application, each drainage pipe group 300 includes a plurality of drainage pipes 310 , and the plurality of drainage pipes 310 are arranged at equal intervals along the length direction of the water receiving tray 100 .

[0115] The multiple drain pipes 310 of each drain pipe group 300 are arranged in sequence at equal intervals along the length direction of the water receiving tray 100 to ensure that a drain pipe 310 is arranged at each area position of the water receiving tray 100, thereby ensuring that a drain pipe 310 is configured at each area position of the drain tray, which can ensure that the water flow in each area of ​​the water receiving tray 100 is discharged to the outside of the unit, thereby ensuring the uniformity of drainage of the water receiving tray 100.

[0116] In some embodiments of the present application, the main heating component 200 includes:

[0117] A main heating section 210 arranged in two water receiving tanks 121;

[0118] and auxiliary heating sections 220 connected to both ends of the main heating section 210 , wherein the auxiliary heating sections 220 are arranged on the protruding portion 110 .

[0119] The main heating section 210 is extended along the length direction of the water receiving groove 121. When arranged, the main heating section 210 is set in contact with the bottom surface of the water receiving groove 121 to ensure that it can heat the defrost water regardless of the water level in the water receiving tray 100.

[0120] The auxiliary heating section 220 is arranged on the protrusion 110 and can be used to indirectly transfer heat to the water receiving tray 100, and transfer heat to the water receiving groove 121 adjacent to the protrusion 110 through the protrusion 110 to achieve the function of indirect auxiliary heating.
