Computer room dedicated cabinet air conditioning system

This creation is about an air conditioning system, especially a computer room dedicated cabinet air conditioning system.

There are many types of air conditioning systems available today, from early window types, box types used in large spaces, or now widely accepted discrete types, and many types of air conditioning systems, except Widely known as the cold room effect, there is also an air conditioning system that has both dehumidification and warm room effects.

The above air conditioning system can be seen in various office buildings, computer rooms or households, and it usually installs different types of air conditioning systems depending on the user's needs and their space conditions. Currently, the common air conditioning systems in the market are mainly from outdoor units. The compressor compresses a low-pressure medium-temperature liquid refrigerant into a high-pressure high-temperature gaseous refrigerant, and sends it to a heat exchanger to cool it into a high-pressure medium-temperature liquid refrigerant, which is then sent to a condenser to cool down to become a high-pressure low-temperature liquid. The refrigerant, and the high-pressure low-temperature liquid refrigerant is depressurized into a low-pressure low-temperature liquid refrigerant through an expansion valve, and the low-pressure low-temperature liquid refrigerant is sent to the cooling coil of the indoor unit, and the external hot air is taken in by a fan. And exchange heat energy with the cooling coil here, so that cold air can be blown into the room, and the refrigerant in the cooling coil forms a low-pressure medium-temperature liquid refrigerant immediately after heat exchange, and then sent back to the outdoor unit. The compressor is compressed, and the operation is repeated, so that the air conditioning system continuously blows out the cold air.

Most of the above air-conditioning systems are planned according to the size of the space at the time of installation, which means that when the number of tonnages of the air-conditioning system is determined, if the space is changed or the environmental factors cause the cold room of the air-conditioning system to be too weak, For example, the number of computers in a computer room often changes the number of computers. When the number of computers is too large, the air defense system's cold prevention effect will be worse. Therefore, the usual solution is to add another air conditioning system or replace it with a cold room effect. A strong air-conditioning system is used as a countermeasure, but this method is too wasteful for the user, and if it is a new air-conditioning system, it is necessary to take extra space for the newly added air-conditioning system, which is inconvenient. In view of the above problems, it is necessary to seek a viable solution.

About this creation department provides a computer room-specific cabinet air-conditioning system, which mainly installs a heat exchanger that can increase or decrease the number in the indoor unit of the air-conditioning system, so as to increase or decrease the effect of the cold room or the warm room at any time according to the user's demand.

The technical means for achieving the above object is that the air conditioning system includes one or more indoor units and one or more outdoor units, wherein the indoor unit includes: a body that is hollow, and the machine is provided with a body a hot water inlet, an ice water inlet and a second warm water outlet; one or more cold coils are provided in the body and can be increased or decreased, and have an output end and an input end, and the input end and the output end respectively The ice water inlet on the body is connected with a warm water outlet, and the outer wall of the cold coil is provided with a plurality of heat dissipation fins; One or more hot coils are disposed in the body and have an output end and an input end, and the input end and the output end are respectively connected to the hot water inlet and the other warm water outlet on the body, The outer wall of the hot coil has a plurality of fins; more than one fan is disposed in the body and opposite to the hot coil and the cold coil; the outdoor unit includes: a compressor having a refrigerant inlet and a a refrigerant recovery device, which is mainly provided with a refrigerant coil in a hot water tank, the hot water tank has a water inlet and a water outlet, one end of the refrigerant coil is connected with a refrigerant outlet of the compressor; And a refrigerant inlet and a refrigerant outlet, the refrigerant inlet of the condenser is connected to the other end of the refrigerant coil of the heat recovery device; an expansion valve has an input end and an output end, and the input end is connected to the condenser a refrigerant outlet connection; an ice water device is mainly provided with a first coil and a second coil in a cold water tank, the two ends of the first coil and the output end of the expansion valve and the compressor Refrigerant inlet connection; The two coils respectively form an ice water outlet and a warm water recovery port, which are respectively connected with the cold coil of the indoor unit; the air conditioning system formed by the above structure has the effect of the cold room and the greenhouse, and if the cold room effect is required, The refrigerant compressed by the compressor of the outdoor unit is a high-pressure high-temperature gaseous refrigerant, and a low-temperature liquid refrigerant is formed through the heat recovery device and the condenser, and then the pressure is reduced to a low pressure by the expansion valve, and then the first coil is passed through, and the first coil is used. After the tube and the cold water tank exchange heat energy, the water stored in the cold water tank is formed into ice water and the second coil heat energy is exchanged to make the ice water output of the ice water device The mouth can flow out the ice water to the body, and the ice water inlet flows into the cold coil, and the fan draws in the outside air to exchange heat energy with the cold coil to form cold air, and then blows into the indoor space, and the ice in the cold coil at this time The water thus turns into warm water and flows out from a warm water outlet, and flows back to the second coil of the ice water device to repeatedly output the ice water outlet to output ice water, and at the same time, the first coil The refrigerant inside forms a medium temperature and flows into the compressor for the compressor to compress again. The repeated operation can continuously blow out the cold air. Conversely, if the warm room effect is required, the high-pressure high-temperature gaseous refrigerant flowing out of the compressor passes through. After the heat recovery device exchanges heat with the low-temperature and medium-temperature warm water of the hot water tank, the heat recovery device can send the low-pressure hot water and flow into the heat coil through the hot water inlet of the body, and the air is taken in through the fan. The heat exchange is performed, and the hot air is blown out to the indoors. At this time, the hot water is converted into low-pressure warm water, and is discharged from another warm water outlet, and flows back into the hot water tank of the heat recovery device, and the compressor sends out height of After the high-temperature gaseous refrigerant passes through the heat recovery device, a high-pressure medium temperature is formed, and then the condenser and the expansion valve become a low-pressure low-temperature liquid refrigerant, and then exchanged with the warm water heat energy in the cold water tank to make the refrigerant form. After the warm gas state, it flows into the compressor and then compresses. After repeated operation, the heating can be continuously blown out to the indoor space. In the above design, the cold coil and the hot coil system of the indoor unit can be increased or decreased according to the demand, such as cooling capacity. When it is insufficient, the flow direction of the cold water circuit is changed to form a double cooling coil to improve the cooling effect, thereby improving the efficiency of heat exchange in the same space of the body, so that the number of indoor units can be increased without increasing the number of indoor units. In the state, the effect of cooling room or greenhouse is improved, so as to reduce the waste of resources, and no additional waste of space.
