Description

A Separate Type Constant Temperature and Humidity Chamber

The present invention relates to a constant temperature and humidity device, and more particularly, in a constant temperature and humidity device for constant temperature and humidity of a computer room, a humidifier, a condenser, a compressor, a cooling water pipe, and a humidification pipe among components of the constant temperature and humidity device are located outside the computer room. An improved thermo-hygrostat device with no possibility of leaking is configured.

Computer circuit boards and memory chips of computers and electronic devices are very sensitive to changes in temperature and humidity, and are likely to malfunction due to only a slight rise or fall of temperature or humidity. The maintenance of temperature and humidity, ie, constant temperature and humidity, is strictly required.

Constant temperature means constant temperature, and constant humidity means constant humidity, so constant temperature and humidity is to maintain an internal space such as a computer room at a constant temperature and humidity. First, computer equipment that requires precision for constant temperature should be kept at a constant temperature to prevent errors caused by temperature expansion of the device or shrinkage expansion due to temperature change. Typical temperature conditions are 20 ° C ± 2 ° C, depending on equipment requirements. For the following humidity, if the ambient air dew point is always lower than the temperature due to its own temperature change in the computer equipment, it is possible to prevent condensation and rust on the surface. High humidity causes various problems due to mold, corrosion, condensation, etc., and too low humidity may cause malfunction of computing equipment due to static electricity. Computer room humidity conditions are typically around 50% ± 5% and can vary depending on the equipment requirements.

Various constant temperature and humidity devices for maintaining a constant temperature and humidity in the computer room for the constant temperature and humidity are provided. The thermo-hygrostat is classified into a water-cooled thermo-hygrostat and an air-cooled thermo-hygrostat according to the cooling method of the condenser. When the distance between the outdoor unit installation location and the thermo-hygrostat in the computer room is long, the heat generated by the thermo-hygrostat is cooled. The water-cooled constant temperature and humidity device which transfers heat from the outdoor unit to the air through the pipe through the pipe is mainly used. In other words, the water-cooled installation is better if the one-way is about 25M or more, including the horizontal and vertical distance, the cooling efficiency is superior to the air-cooled (for example, the field measurement results at about 45% better than the horizontal 40M, 25M vertical distance), refrigerant Constant pressure and flow, less influence from outdoor load fluctuations, fewer pipes, longer compressor life than air-cooled, no outdoor unit noise near computer room windows, good aesthetics, and other distance and efficiency advantages Therefore, almost all computer rooms are equipped with water-cooled thermo-hygrostats.

Figure 1 schematically shows a conventional water-cooled constant temperature and humidity device. Referring to the drawings, the conventional thermo-hygrostat is a compressor 110, condenser 120, evaporator 130, blower 140, reheat heater 150, humidifier 160, dust collecting filter 170, cooling water The pipe 180 is configured to include a humidifying pipe 190.

The compressor 110 compresses the gaseous refrigerant of low temperature and low pressure to form a refrigerant of high temperature and high pressure, and transfers the refrigerant to the condenser, and the condenser 120 exchanges gaseous refrigerant of high temperature and high pressure with the cooling water transferred through the cooling water pipe 180 from the cooling tower. It is made of a high-pressure liquid refrigerant, the evaporator 130 is a part that exerts the actual refrigerant effect by the evaporation of the refrigerant by converting the high-pressure liquid refrigerant to indoor air by heat exchange with the indoor air. The blower 140 circulates indoor air to a blower, a computer room, a dust collecting filter, an evaporator, and a blower, and the reheat heater 150 performs heating when the room temperature is low or compensates for room temperature when the dehumidification circuit is operated. The humidifier 160 automatically humidifies the water transferred from the water tank through the humidifying pipe 190 when the humidity is low. The dust collecting filter 170 removes dust, microorganisms, odors, etc. generated in the computer room.

Referring to the constant temperature and humidity action of the constant temperature and humidity device 100, the heat generated from the computer equipment cools and the hot air passes through the dust collecting filter 170 of the constant temperature and humidity chamber 100, removes the dust and the evaporator 130 Cooling while passing through the cooling coil of the air is supplied to the computer room by the blower 140. At this time, the compressor 110, the condenser 120, the humidifier 160, the heat heater 150, etc. are operated as necessary by the action of a sensor (not shown) installed at the rear end of the constant temperature and humidity chamber 100, and the temperature of the computer room. And constant temperature and humidity in a manner to maintain humidity.

2 is a layout view of a conventional water-cooled constant temperature and humidity device. Referring to the drawings, the condenser 120 of the components of the conventional water-cooled constant temperature and humidity device requires a coolant pipe 180 for the transfer of the coolant for cooling the refrigerant of high temperature and high pressure, such a coolant pipe 180 Is preferably transferred from the cooling tower 210 disposed on the roof outside of the computer room through the pump 220 and transferred to the condenser 120 inside the thermo-hygrostat device 100 to cool the condenser 120 by heat exchange. The condenser 120 again functions as a moving passage of the cooling water transferred to the cooling tower 210.

In addition, the humidifier 160 requires a humidifying pipe 190 for the transfer of the humidifying water to evaporate inside the humidifier to increase the humidity in the computer room. The humidifying pipe 190 may also be provided from the outdoor water tank 230. It is transferred to the constant temperature and humidity device 100 in the computer room of the evaporation inside the device 100 to function as a moving passage of the humidifying water for humidifying the computer room.

Since the conventional constant temperature and humidity apparatus 100 has a configuration in which the condenser 120 and the humidifier 160 are integrally included in the constant temperature and humidity apparatus 100, the cooling water pipe 180 and the humidification pipe 190 are included. As shown in Figure 2 is usually connected directly to the constant temperature and humidity device 100 through the bottom (or ceiling) inside the computer room.

Therefore, such a conventional water-cooled constant temperature and humidity device is a humidifier body built in the cooling water pipe 180 and the humidifying pipe 190 and the constant temperature and humidity device 100 is concealed installed in the bottom or ceiling of the interior of the computer room among the components. Since all of 160 contain water, it is pointed out as a problem that there exists a possibility of a leak accident in piping and a constant temperature and humidity apparatus. A number of leaks actually occur, such as leaks in the humidifier supply, leaks in the main body of the humidifier, leaks in the cooling water pipes, etc. due to various reasons such as aging of pipes, inadvertent operation during maintenance and repair, etc. In case of damage, enormous damage is occurring.

The present invention has been made to solve the problems of the prior art as described above, the constant temperature and humidity of the new structure in which the cooling water and humidification pipe that can structurally prevent the possibility of damage due to the leakage of the pipe is not installed in the computer room at all It is an object to provide a device.
