DETAILED DESCRIPTION
[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0032] Example 1
[0033] like Figure 1 and Figure 3 As shown, the present embodiment provides a dual-purpose air conditioner indoor unit, including a cabinet 11, a compressor 12, an evaporator 13 and two fans 14. The cabinet 11 is vertically arranged, and two partitions 111 are vertically spaced in the cabinet 11. The two partitions 111 divide the cabinet 11 into two end chambers 112 spaced apart from each other and a middle chamber 113 located between the two end chambers 112. The compressor 12 is arranged in the middle chamber 113. The cabinet 11 is provided with an air inlet 1121 and an air outlet 1122 connected to each of the end chambers 112. An evaporator 13 is arranged at each of the air inlet 1121. The two fans 14 correspond to the two end chambers 112 one by one. Each fan 14 is arranged in the corresponding end chamber 112, and the air outlet end of each fan 14 faces the corresponding end chamber 112. The air outlet 1122 of the end chamber 112, one port of the multiple evaporators 13 is connected to a port of the compressor 12, and the other ports of the compressor 12 and the multiple evaporators 13 are respectively used to connect with two ports of the condenser. In this way, for the end chamber, the evaporator at the air inlet is used to cool the air entering the end chamber, and the fan in the end chamber blows out the cold air in the end chamber. The middle chamber is for installing the compressor. The cold air in the upper end chamber is used to cool the room, and the cold air in the lower end chamber is cooled to the trench in the CT room. In this way, the dual-purpose air-conditioning indoor unit can cool the room and the CT machine at the same time, and the compressor is set in the middle chamber. This is to improve the applicability of the equipment, keep the operating temperature of the compressor close to the indoor temperature, and its operation is stable.
[0034] In this embodiment, at least one air inlet can be set corresponding to each end chamber, so that the cooling effect can be controlled. For example, two air inlets can be set corresponding to the end chamber located at the top, and one air inlet can be set corresponding to the end chamber located at the bottom, and the air inlet is covered by a grille-shaped evaporator.
[0035] The air outlet end of the fan described in this embodiment can be directly connected to the corresponding air outlet.
[0036] In this embodiment, the side wall on any side of the end chamber can be directly open and form an air inlet.
[0037] The reason why the compressor is arranged in the cabinet in this embodiment is that the compressor has a minimum operating temperature, which is usually about ten degrees below zero. For areas with extremely cold winters, if the compressor is placed in the outdoor unit, it will not be able to start. Therefore, it is arranged in the cabinet and placed indoors together with the cabinet, so that it can operate normally in extremely cold areas in winter (after all, the indoor temperature in extremely cold areas will not be below 10 degrees Celsius below zero).
[0038] In the above technical solution, the air inlets 1121 are all arranged on the side walls of the cabinet 11, and the air outlets 1122 are arranged at the upper and lower ends of the cabinet 11, so that the air outlets located at the upper end blow out cold air upward to cool the room, and the air outlets located at the lower end blow out cold air downward to cool the trench in the CT room.
[0039] In the above technical solution, the compressor 12 is installed in the middle chamber 113 through the shock-absorbing seat 15. By providing the shock-absorbing seat, the noise during the operation of the compressor can be reduced.
[0040] The above technical solution also includes a humidifier 16 disposed in the cabinet 11, and the humidifier 16 is used to humidify the end chamber 112 located above, so that the humidifier can humidify the cold air in the end chamber located above, thereby achieving indoor cooling and humidification, which can maintain the indoor humidity and improve the working comfort of the staff. Preferably, the humidifier can be disposed in the middle chamber, but its mist outlet extends upward to the end chamber located above.
[0041] The inner wall of the cabinet 11 described in the above technical solution is provided with a sound insulation layer (which may be a sound insulation and heat insulation cotton with sound insulation and heat insulation functions), which can further reduce the noise of the entire dual-purpose air conditioner indoor unit during operation.
[0042] In the above technical solution, a plurality of supporting legs 114 are further provided at the lower end of the cabinet 11, so that the bottom of the cabinet can be suspended in the air to avoid falling to the ground and getting wet.
[0043] like Figure 2 As shown, the air outlet 1122 in the above technical solution is provided with a grille cover 115, so as to prevent insects or foreign objects from entering the end chamber.
[0044] The fan 14 described in the above technical solution is a low-noise fan (under the same air volume supply conditions, a fan with large blades and low speed can be selected, so that its noise is relatively low), which can further reduce the operating noise of the dual-purpose air conditioner indoor unit.
[0045] At least one side panel is detachably mounted on the side walls of the cabinet body corresponding to the middle chamber and the end chamber, so that the corresponding side panel can be removed to maintain and protect the components inside, such as adding water to the humidifier.
[0046] Example 2
[0047] like Figure 4 and Figure 5 As shown, this embodiment provides a rapid cooling air conditioner in a machine room, including an outdoor unit 2 and a dual-purpose air conditioner indoor unit 1 as described in Example 1, wherein the outdoor unit 2 is arranged outdoors in the CT machine room, and the cabinet 11 is arranged in the trench indoors in the CT machine room, and a condenser 21 is arranged in the outdoor unit 2, and the other ports of the compressor 12 and the plurality of evaporators 13 are respectively connected to the two ports of the condenser 21 through pipes (the pipes can be copper pipes), so that the outdoor unit and the dual-purpose air conditioner indoor unit 1 together form a complete air conditioning device, except that the air conditioning device has two cold air outlets and faces different directions for dual use. Of course, an expansion valve 23 can also be arranged in the cabinet, and the expansion valve is arranged between the connection point between the condenser and the plurality of evaporators.
[0048] The outdoor unit 2 in the above technical solution also includes a cabinet 22, the condenser 21 is arranged in the cabinet 22, and a heat dissipation window 221 is arranged on the cabinet 22. Both ports of the condenser 21 are extended to the outside of the cabinet 22. Its structure is simple and makes it easy to install the outdoor unit outdoors.
[0049] The rapid cooling air conditioner in the CT room provided in this embodiment can maintain normal operation in both winter and summer. In summer, it is mainly for cooling, while in winter, the room can be heated. This makes the temperature in the CT room around 15-20°C, which makes it comfortable. At the same time, for the CT machine, its heat dissipation is also stable, and there will be no obvious heat dissipation wind noise due to the heavy heat dissipation load.
[0050] in, Figure 5 It mainly represents the refrigerant circulation loop composed of the compressor 12, the evaporator 13, the condenser 21 and the expansion valve 23. Of course, the other components in the circulation loop belong to the common knowledge in the field and are not described here. In addition, a fan with an air outlet aligned with the heat dissipation window can be added to the cabinet, so that the fan can accelerate the air flow in the cabinet.
[0051] In this embodiment, the trench in the CT machine room is used for routing the cables of the CT machine, and is communicated with the internal annular cavity of the CT machine. When the air outlet of the dual-purpose air-conditioning indoor unit located below blows cold air into the trench, the cold air will enter the annular cavity. When the CT machine is started, the temperature in the annular cavity is relatively low due to the action of the dual-purpose air-conditioning indoor unit, so the operating power of the cooling system of the CT machine will not be too high. At this time, the noise during heat dissipation is small, and silent operation can be maintained.
[0052] In this embodiment, since the power of the CT machine is relatively large, a large amount of heat will be generated at the moment of startup. In order to dissipate the heat in time, the rapid cooling air conditioner in the CT machine room provided by this embodiment needs to be able to quickly increase a large amount of cold energy to dissipate the heat. However, it is necessary to reduce the speed at which the cold air is sent out (to maintain a relatively quiet state), so the dual-use air conditioner indoor unit needs to maintain a low wind speed and high temperature difference state (that is, the delivered cold air temperature is low, but the air volume is small). This requires the use of an evaporator with a relatively large area to quickly cool the airflow (on the one hand, the temperature of the airflow can be lower, and on the other hand, it can avoid the cold energy from accumulating on the evaporator and causing condensation and ice on the evaporator, affecting the operation of the equipment). That is, the rapid cooling air conditioner in the machine room has the characteristic of rapid cooling.
[0053] Of course, the rapid cooling air conditioner in the machine room provided by this embodiment is not only used for cooling the CT machine room and the CT machine, but can also be used to cool other equipment rooms. Of course, for each of the end chambers, the setting positions of the air inlet and the air outlet can be adjusted as needed, and the direction of the air outlet of the fan is also adjusted according to the position of the corresponding air outlet (taking the end chamber located at the top as an example, the air outlet and the air inlet can be set on the side wall, and of course the air inlet can also be set on the top wall, and the air outlet can be set on the side wall).
[0054] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
