Description

Technical Field

[0001] This utility model relates to the field of water-cooled unit technology, and in particular to an energy-saving device for water-cooled units. Background Technology

[0002] The refrigerant exiting the evaporator is in a gaseous state. After adiabatic compression by the compressor, it becomes a high-temperature, high-pressure state. The compressed gaseous refrigerant is then isobarically cooled and condensed in the condenser, transforming into a liquid refrigerant. This liquid refrigerant then expands to a low pressure through a throttling valve, becoming a gas-liquid mixture. The low-temperature, low-pressure liquid refrigerant absorbs heat from the substance being cooled in the evaporator, returning to a gaseous state. The gaseous refrigerant then re-enters the compressor through piping, beginning a new cycle. These are the four processes of the refrigeration cycle.

[0003] The chiller unit may encounter the following problems during actual operation:

[0004] 1. During the cooling water circulation process in a chiller unit, the unit usually operates at full power according to the set setting. However, the target temperature will change accordingly during the cooling process. If the unit continues to operate at full power during the cooling water circulation process, it will inevitably lead to a large amount of unnecessary waste of electrical energy.

[0005] 2. When the chiller unit is working, it will generate a lot of vibration and noise. This noise will be transmitted to the floor slab through the vibration, causing the noise to be transmitted to the apartment below and causing unnecessary trouble to the tenants in the apartment. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide an energy-saving device for chiller units, so as to solve the technical problem that the chiller units do not continue to operate at full power due to changes in cooling temperature during the cooling water circulation process, which greatly increases the power consumption of the chiller units, and at the same time, the vibration and noise generated by the chiller units during use are transmitted to the floors below.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] An energy-saving device for a chiller unit includes a mounting frame, an evaporator fixedly mounted on the inner surface of the mounting frame, a condenser disposed on the inner surface of the mounting frame away from the evaporator, a connecting frame fixedly mounted on the top of the mounting frame, shock-absorbing and sound-insulating cotton fixedly mounted on the inner surface of the connecting frame, a compressor fixedly mounted on the inner surface of the shock-absorbing and sound-insulating cotton, a rubber pad fixedly mounted on the bottom of the mounting frame, and cooling mechanisms fixedly mounted on the back of both the condenser and the evaporator.

[0010] As an improved technical solution, the cooling mechanism includes a cooling box, the left side of which is fixedly connected to the right side of the evaporator and the condenser. A placement rack is fixedly installed on the inner surface of the cooling box, and four sets of heat dissipation components are fixedly installed on the inner surface of the placement rack.

[0011] As an improved technical solution, the heat dissipation component includes a motor, the outer surface of which is fixedly connected to the inner surface of the mounting frame, and a rotating shaft is fixedly mounted on the output end of the motor via a coupling, with heat dissipation blades fixedly mounted on the outer surface of the rotating shaft.

[0012] As an improved technical solution, the cooling mechanism also includes coolant pipes, the outer surfaces of which are fixedly connected to the inner surfaces of the cooling tank and the condenser.

[0013] As an improved technical solution, the cooling mechanism further includes an air intake plate, the outer surface of which is fixedly connected to the inner surface of the cooling box, and a conical air intake port is provided on the outer surface of the air intake plate.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes the combined use of a motor and rotating shaft with heat dissipation blades and an air intake plate, and the combined use of the air intake plate and conical air inlet with the coolant pipe, to activate several heat dissipation components according to the power of the chiller unit, thereby reducing the power consumption of the cooling system in the chiller unit and achieving the energy-saving effect of the chiller unit. At the same time, by utilizing the different diameters on both sides of the conical air inlet, the air intake pressure increases, thereby increasing the heat dissipation airflow and improving the heat dissipation effect under the same power.

[0016] 2. This utility model reduces the vibration and noise generated by the compressor in the chiller unit by adding a design. Through the use of connecting frame and anti-vibration sound insulation cotton, compressor and fixed frame, and fixed frame and rubber pad, the vibration and noise generated by the compressor during operation are filtered through multiple layers, thereby reducing the vibration and noise and preventing large vibration and noise from being transmitted to the floors below, thus avoiding the problem of disturbing residents during the operation of the chiller unit.

[0028] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides an energy-saving device for a chiller unit. This energy-saving device for a chiller unit includes a fixed frame 1, an evaporator 2 fixedly installed on the inner surface of the fixed frame 1, a condenser 3 disposed on the inner surface of the fixed frame 1 away from the evaporator 2, a connecting frame 4 fixedly installed on the top of the fixed frame 1, an anti-vibration and sound insulation cotton 5 fixedly installed on the inner surface of the connecting frame 4, a compressor 6 fixedly installed on the inner surface of the anti-vibration and sound insulation cotton 5, a rubber pad 7 fixedly installed on the bottom of the fixed frame 1, and a cooling mechanism 8 fixedly installed on the back of both the condenser 3 and the evaporator 2.

[0029] The shock-absorbing and sound-insulating cotton 5 has multiple sponge holes, which can absorb some of the vibration and noise, while the compressor 6 is fixed to the connecting frame 4 by bolts.

[0030] like Figure 1 and Figure 3 As shown, the cooling mechanism 8 includes a cooling box 81. The left side of the cooling box 81 is fixedly connected to the right side of the evaporator 2 and the condenser 3. A placement rack 82 is fixedly installed on the inner surface of the cooling box 81. Four sets of heat dissipation components 83 are fixedly installed on the inner surface of the placement rack 82.

[0031] like Figure 1 and Figure 3 As shown, the heat dissipation assembly 83 includes a motor 831, the outer surface of the motor 831 is fixedly connected to the inner surface of the mounting bracket 82, the output end of the motor 831 is fixedly mounted with a rotating shaft 832 via a coupling, and heat dissipation blades 833 are fixedly mounted on the outer surface of the rotating shaft 832.

[0032] Motor 831 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0033] like Figure 1 and Figure 3 As shown, the cooling mechanism 8 also includes a coolant pipe 84, the outer surface of which is fixedly connected to the inner surface of the cooling box 81 and the condenser 3.

[0034] Coolant flows inside coolant pipe 84 and is driven by a water pump.

[0035] like Figure 3 and Figure 4 As shown, the cooling mechanism 8 also includes an air intake plate 85, the outer surface of which is fixedly connected to the inner surface of the cooling box 81, and a conical air intake port 86 is provided on the outer surface of the air intake plate 85.

[0036] During operation, the vibration noise generated by the compressor 6 in the chiller unit is first partially absorbed by the anti-vibration and sound insulation cotton 5, then transmitted and partially dampened by the condenser 3 and evaporator 2 below, and then partially offset by the rubber pad 7 under the mounting bracket 1, thus largely eliminating the vibration noise of the compressor 6. When the chiller unit is in use, the coolant pipe 84 in the condenser 3 circulates the coolant through the water pump. When it circulates into the cooling box 81, the chiller unit will start several of the four heat dissipation components 83 through the operating power. The motor 831 drives the heat dissipation blades 833 to rotate through the rotating shaft 832, drawing outside air into the cooling box 81 through the conical air inlet 86 on the air inlet plate 85 to dissipate heat from the coolant pipe 84. Since the wide opening of the conical air inlet 86 faces outward, the air is compressed and then enters the cooling box 81, increasing the air pressure inside the cooling box 81 and making the airflow faster, so that the heat on the coolant pipe 84 is dissipated more quickly.

[0037] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
