In this way, it is inconvenient to arrange the connecting pipes, and the appearance is messy. Utility Model Content

[0004] Based on this, it is necessary to provide a chiller for year-round refrigeration that can easily arrange connecting pipes and has a more compact structure.

[0005] A chiller for year-round refrigeration comprises a compressor, a heat recovery device, a liquid reservoir, an evaporator, connecting pipes and a support base, wherein the compressor, the heat recovery device, the liquid reservoir and the evaporator are connected through connecting pipes to form a refrigerant circuit, and the liquid reservoir and the evaporator are both installed on the support base; the liquid reservoir and the evaporator both extend along a first direction X; and, along a second direction Y, the liquid reservoir is located below the evaporator, and along a third direction Z, the liquid reservoir and the evaporator are staggered to form a first space and a second space in the third direction Z, and the second space is staggered with the first space; wherein part of the connecting pipes are arranged in the first space, and the heat recovery device is arranged in the second space; the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other.

[0006] In one embodiment, along the second direction Y, the heat recovery device is connected to the top of the liquid reservoir and extends along the first direction X; the compressor is connected to the top of the evaporator and extends along the first direction X, and along the third direction Z, the heat recovery device and the evaporator are arranged in parallel. It can be understood that, in such a configuration, the liquid reservoir supports the heat recovery device, and the evaporator supports the compressor, so that the liquid reservoir, the heat recovery device, the evaporator and the compressor can be integrated together, which is conducive to improving the integration of the chiller for year-round cooling. In addition, the liquid reservoir, the heat recovery device, the evaporator and the compressor are arranged in parallel with each other, which can make full use of the space and make the structure of the chiller for year-round cooling more compact.

[0007] The support base includes a first support plate and a second support plate arranged at intervals along a first direction X, the liquid reservoir and the evaporator are both installed between the first support plate and the second support plate, and the first support plate and the second support plate are both arranged in an L shape. It can be understood that such an arrangement facilitates the diagonal arrangement of the liquid reservoir and the evaporator in the three-dimensional space formed by the first direction X, the second direction Y and the third direction Z, and can save the material of the support base.

[0008] In one embodiment, the chiller for year-round cooling further includes a condenser, the heat recovery device includes an outlet end, the outlet end is connected to the inlet of the condenser, and the connecting pipeline further includes a connecting pipe, one end of the connecting pipe is connected to the outlet of the condenser, and the other end of the connecting pipe is connected to the refrigerant inlet of the liquid reservoir. It can be understood that, with such a configuration, the refrigerant in the heat recovery device can enter the inlet of the condenser through the outlet end, and then the refrigerant enters the connecting pipe from the outlet of the condenser and flows into the refrigerant inlet of the liquid reservoir through the connecting pipe.

[0009] In one embodiment, along the third direction Z, the outlet and the connecting pipe are located on both sides of the heat recovery device and are arranged away from each other; one end of the connecting pipe used to connect to the outlet of the condenser is overlapped above the evaporator along the second direction Y and is located between the compressor and the evaporator, and the other end of the connecting pipe is wound around to communicate with the refrigerant inlet of the liquid storage device. It can be understood that such a configuration can avoid interference between the connecting pipe and the heat recovery device. In addition, the evaporator can support the connecting pipe, thereby facilitating the installation and fixing of the connecting pipe.

[0010] In one embodiment, the connecting pipeline also includes an air outlet pipe, along the first direction X, one end of the heat recovery device close to the first support plate is configured as the first end, and one end of the heat recovery device close to the second support plate is configured as the second end, and the second end is spaced apart from the second support plate; one end of the air outlet pipe is connected to the air outlet of the compressor, and the other end is connected to the second end. It can be understood that, in this embodiment, the second end is configured as the inlet end of the heat recovery device, and the high-temperature and high-pressure refrigerant vapor flowing out of the compressor outlet flows into the second end of the heat recovery device, that is, the inlet end, through the air outlet pipe. In addition, since the second end is spaced apart from the second support plate, interference between the air outlet pipe and the second support plate can be avoided.

It can be understood that, in such a configuration, the heat recovery water is passed into the heat recovery water channel from the water inlet, absorbs the heat of the refrigerant in the refrigerant channel and heats up, and then flows out from the water outlet. By arranging the water inlet and the water outlet at the same end of the heat recovery device, it is convenient for the heat recovery device to be connected to an external water supply pipeline.

[0012] In one embodiment, the connecting pipeline further includes a bypass pipeline, one end of the bypass pipeline is connected to the air outlet pipe, the other end of the bypass pipeline is connected to the liquid reservoir, and a first switch valve is provided on the bypass pipeline; along the first direction X, the bypass pipeline is located between the air outlet pipe and the second support plate. It can be understood that, in this arrangement, the bypass pipeline is arranged in parallel with the condenser, and the bypass pipeline can be connected or disconnected by the first switch valve, so as to ensure that the chiller for year-round refrigeration can be started smoothly in a low temperature environment.

[0013] In one embodiment, the connecting pipeline also includes a throttle tube group, one end of the throttle tube group is connected to the refrigerant outlet of the liquid storage device, and the other end is connected to the evaporator, and a throttle valve element is provided on the throttle tube group for throttling and reducing the pressure of the refrigerant.

[0014] In one embodiment, along the second direction Y, the refrigerant outlet is located at the bottom of the accumulator, and part of the throttle tube assembly is installed in the first space and connected to the evaporator. It can be understood that such an arrangement can not only fully utilize the first space, but also reduce the shaking of the throttle tube assembly.

[0015] Compared with the prior art, the present application provides a chiller with year-round cooling. The support seat is used to support the reservoir and the evaporator. Since the reservoir and the evaporator both extend along the first direction X; and along the second direction Y, the reservoir is located below the evaporator, and along the third direction Z, the reservoir and the evaporator are staggered. Therefore, in the three-dimensional space formed by the first direction X, the second direction Y and the third direction Z, the reservoir and the evaporator are parallel to each other and distributed diagonally, so that two diagonally distributed avoidance spaces are formed above the reservoir and below the evaporator—the second space and the first space. In addition, the second space and the first space provide accommodation space for the heat recovery device and some connecting pipes, which is convenient for the chiller with year-round cooling to arrange the connecting pipes and the heat recovery device, so that the appearance of the chiller with year-round cooling looks more beautiful.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0028] See also Figures 1 to 5 The present application provides a chiller for year-round refrigeration, which comprises a compressor 10, a heat recovery device 20, a liquid reservoir 40, an evaporator 50, a connecting pipe 61 and a support base 70. The compressor 10, the heat recovery device 20, the liquid reservoir 40 and the evaporator 50 are connected through the connecting pipe 61 to form a refrigerant circuit, and the liquid reservoir 40 and the evaporator 50 are both installed on the support base 70. The liquid reservoir 40 and the evaporator 50 extend along the first direction X; and along the second direction Y, the liquid reservoir 40 is located below the evaporator 50, and along the third direction Z, the liquid reservoir 40 and the evaporator 50 are staggered to form a first space 51 and a second space 52 in the third direction Z, and the second space 52 is staggered with the first space 51; wherein, part of the connecting pipe 61 is arranged in the first space 51, and the heat recovery device 20 is arranged in the second space 52; the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other.

[0029] The support seat 70 is used to support the liquid reservoir 40 and the evaporator 50. Since the liquid reservoir 40 and the evaporator 50 extend along the first direction X, and the liquid reservoir 40 is located below the evaporator 50 along the second direction Y, and the liquid reservoir 40 and the evaporator 50 are staggered along the third direction Z, the liquid reservoir 40 and the evaporator 50 are parallel to each other and diagonally distributed in the three-dimensional space formed by the first direction X, the second direction Y and the third direction Z, so that two diagonally distributed avoidance spaces are formed above the liquid reservoir 40 and below the evaporator 50—the second space 52 and the first space 51. In addition, the second space 52 and the first space 51 provide accommodation space for the heat recovery device 20 and part of the connecting pipe 61, which facilitates the arrangement of the connecting pipe 61 and the heat recovery device 20 in the chiller for year-round cooling, thereby making the appearance of the chiller for year-round cooling look more beautiful.

[0030] like Figure 3 and Figure 4 As shown, along the second direction Y, the heat recovery device 20 is connected to the top of the liquid reservoir 40 and extends along the first direction X; the compressor 10 is connected to the top of the evaporator 50 and extends along the first direction X; along the third direction Z, the heat recovery device 20 and the evaporator 50 are arranged in parallel. In this way, the liquid reservoir 40 supports the heat recovery device 20, and the evaporator 50 supports the compressor 10, so that the liquid reservoir 40, the heat recovery device 20, the evaporator 50 and the compressor 10 can be integrated together, which is conducive to improving the integration of the chiller for year-round cooling. In addition, the liquid reservoir 40, the heat recovery device 20, the evaporator 50 and the compressor 10 are arranged in parallel with each other, which can make full use of the space and make the structure of the chiller for year-round cooling more compact.

[0031] Furthermore, if Figure 4 As shown, the support base 70 includes a first support plate 71 and a second support plate 72 arranged at intervals along the first direction X, and the liquid reservoir 40 and the evaporator 50 are installed between the first support plate 71 and the second support plate 72. The first support plate 71 and the second support plate 72 are arranged in an L shape. In this way, the same end of the liquid reservoir 40 and the evaporator 50 along the first direction X can be connected to the two short sides of the L-shaped first support plate 71 or the second support plate 72 respectively. That is, it is convenient to arrange the liquid reservoir 40 and the evaporator 50 diagonally in the three-dimensional space formed by the first direction X, the second direction Y and the third direction Z, and the material of the support base 70 can be saved.

[0032] See also Figure 2 , Figure 4 and Figure 5The year-round refrigeration chiller also includes a condenser 30, a heat recovery device 20 includes an outlet port 26, and the outlet port 26 is connected to the inlet of the condenser 30. The connecting pipeline 61 includes a connecting pipe 611, one end of the connecting pipe 611 is connected to the outlet of the condenser 30, and the other end is connected to the refrigerant inlet 41 of the liquid storage device 40. In this way, the refrigerant in the heat recovery device 20 can enter the inlet of the condenser 30 through the outlet port 26, and then the refrigerant enters the connecting pipe 611 from the outlet of the condenser 30, and flows into the refrigerant inlet 41 of the liquid storage device 40 through the connecting pipe 611.

[0033] Optionally, the condenser 30 is configured as an air-cooled condenser, and the air-cooled condenser is arranged outdoors, and the refrigerant in the condenser exchanges heat with the air in the external environment, thereby releasing heat and condensing. The connecting pipe 611 is provided to facilitate the outdoor air-cooled condenser to be connected to the liquid storage tank 40.

[0034] For further information, see Figure 5 A second switch valve 611a is provided on the connecting pipe 611. The second switch valve 611a is used to close the connecting pipe 611, thereby isolating the refrigerant circuit, which is convenient for the staff to diagnose and repair the refrigerant circuit. The second switch valve 611a can be configured as a ball valve.

[0035] Please continue reading Figure 4 , along the third direction Z, the outlet end 26 and the connecting pipe 611 are located on both sides of the heat recovery device 20 and are arranged away from each other. The connecting pipe 611 is used to connect the outlet of the condenser 30. One end is overlapped above the evaporator 50 along the second direction Y and is located between the compressor 10 and the evaporator 50. The other end of the connecting pipe 611 is wound around to communicate with the refrigerant inlet 41 of the accumulator 40. In this way, interference between the connecting pipe 611 and the heat recovery device 20 can be avoided. In addition, the evaporator 50 can support the connecting pipe 611, thereby facilitating the installation and fixing of the connecting pipe 611.

[0036] Specifically, see Figure 2 A first bracket 53 is provided on the evaporator 50 , and the connecting pipe 611 is installed on the first bracket 53 .

[0037] Please continue reading Figure 4, the connecting pipeline 61 also includes an air outlet pipe 614. Along the first direction X, the end of the heat recovery device 20 close to the first support plate 71 is configured as the first end 21, and the end of the heat recovery device 20 close to the second support plate 72 is configured as the second end 22, and the second end 22 is spaced apart from the second support plate 72. One end of the air outlet pipe 614 is connected to the air outlet 12 of the compressor 10, and the other end is connected to the second end 22. In this embodiment, the second end 22 is configured as the inlet end 25 of the heat recovery device 20, and the high-temperature and high-pressure refrigerant vapor flowing out of the air outlet 12 of the compressor 10 flows into the second end 22 of the heat recovery device 20, that is, the inlet end 25, through the air outlet pipe 614. In addition, since the second end 22 is spaced apart from the second support plate 72, interference between the air outlet pipe 614 and the second support plate 72 can be avoided.

[0038] Optionally, the length of the heat recovery device 20 along the first direction X is half of the length of the liquid storage device along the first direction X. In this way, a sufficiently large space can be reserved between the second end 22 of the heat recovery device 20 and the second support plate 72 .

[0039] like Figure 4 and Figure 5 As shown, a refrigerant channel and a heat recovery water channel are provided in the heat recovery device 20, and the air outlet pipe 614 is connected to the refrigerant channel located at the second end 22. The heat recovery water channel has a water inlet 23 and a water outlet 24, and the water inlet 23 and the water outlet 24 are located at the same end of the heat recovery device 20. The heat recovery water is passed into the heat recovery water channel from the water inlet 23, and absorbs the heat of the refrigerant in the refrigerant channel to heat up, and then flows out from the water outlet 24. That is, the heat recovery water can pre-condense the refrigerant before entering the condenser 30. By arranging the water inlet 23 and the water outlet 24 at the same end of the heat recovery device 20, it is convenient for the heat recovery device 20 to be connected to an external water supply pipeline.

[0040] Optionally, the heat recovery device 20 includes two parts: a shell and a tube body. The shell is used to form a refrigerant channel, and the tube body is located inside the shell and is used to form a heat recovery water channel.

[0041] Furthermore, the water inlet 23 and the water outlet 24 are both opened at the first end 21 , so that interference between the external water supply pipeline and the air outlet pipe 614 and the connecting pipe 611 near the second end 22 can be avoided.

[0042] The connecting pipeline 61 further includes a bypass pipeline 62, one end of which is connected to the air outlet pipe 614, and the other end of which is connected to the liquid reservoir 40. A first switch valve 621 is provided on the bypass pipeline 62. Along the first direction X, the bypass pipeline 62 is located between the air outlet pipe 614 and the second support plate 72.

[0043] That is, the bypass line 62 is arranged in parallel with the condenser 30, and the bypass line 62 can be connected or disconnected by the first switch valve 621. Specifically, when the first switch valve 621 is opened, the bypass line 62 is connected with the heat recovery device 20 and the liquid reservoir 40, and the refrigerant in the heat recovery device 20 is divided into two branches, namely the bypass line 62 and the condenser 30, wherein a part of the refrigerant can directly enter the liquid reservoir 40 through the bypass line 62 without flowing through the condenser 30 for condensation and heat release, so this part of the high-temperature and high-pressure refrigerant can be used as heat and pressure to supplement the liquid reservoir 40, thereby quickly establishing a high-pressure environment in the refrigerant circuit to ensure that the chiller for year-round refrigeration can be smoothly started; the other part of the refrigerant normally flows through the condenser 30 for condensation and heat release, and then flows into the liquid reservoir 40. When the first switch valve 621 is closed, the bypass line 62 is cut off, and the refrigerant in the heat recovery device 20 only flows through the condenser 30 and then flows into the liquid storage tank 40 through the condenser 30 .

[0044] Furthermore, the first switch valve 621 can be configured as a solenoid valve. A one-way valve 622 is also provided on the bypass line 62, and the one-way valve 622 is used to prevent the refrigerant from flowing back.

[0045] like Figure 2 and Figure 3 As shown, the connecting pipeline 61 also includes a throttle tube group 612, one end of the throttle tube group 612 is connected to the refrigerant outlet 42 of the liquid storage tank 40, and the other end is connected to the evaporator 50, and a throttle valve element 612a is provided on the throttle tube group 612, and the throttle valve element 612a can throttle and reduce the pressure of the refrigerant flowing through the throttle tube group 612.

[0046] Furthermore, along the second direction Y, the refrigerant outlet 42 is located at the bottom of the accumulator 40, and part of the throttle tube set 612 is installed in the first space 51 and connected to the evaporator 50. In this way, not only the first space 51 can be fully utilized, but also the shaking of the throttle tube set 612 can be reduced.

[0047] Specifically, Figure 2 As shown, one end of the throttle tube set 612 is connected to the side wall of the liquid reservoir 40, and the other end is passed through the first support plate 71 and connected to the evaporator 50. A second bracket 54 is provided below the evaporator 50, and the middle part of the throttle tube set 612 is connected to the second bracket 54.

[0048] Among them, see Figure 4 The connecting pipeline 61 includes an air intake pipe 613 , and the air intake pipe 613 is used to connect the evaporator 50 and the air intake port 11 of the compressor 10 .

[0049] like Figure 1 and Figure 3As shown, the chiller for year-round cooling also includes a unit frequency conversion control cabinet 80 and a water pump frequency conversion control cabinet 90; the unit frequency conversion control cabinet 80 is installed on the side of the heat recovery device 20 away from the evaporator 50 along the third direction Z. The water pump frequency conversion control cabinet 90 is installed on the evaporator 50 and is spaced apart from the compressor 10 along the first direction X.

[0050] See also Figure 5 The operating principle of the year-round refrigeration chiller is as follows: the compressor 10 sucks in the low-temperature, low-pressure refrigerant vapor from the evaporator and compresses it to do work, turning it into high-temperature, high-pressure superheated vapor. The high-temperature, high-pressure superheated vapor enters the heat recovery device 20, heats the heat recovery water in the heat recovery device 20, and then enters the condenser 30 for condensation, and the refrigerant condenses into a high-pressure liquid. After the high-pressure liquid flows through the liquid storage device 40, it is throttled and decompressed to become a low-temperature, low-pressure, and liquid-rich two-phase gas-liquid mixture. These gas-liquid two-phase mixtures enter the evaporator 50, and after absorbing the heat of the chilled water in the evaporator 50, they become low-temperature, low-pressure refrigerant vapor. The refrigerant vapor is sucked into the compressor 10 again, and the cycle repeats.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
