在博物館里很多展出的文物由于其性質特殊所以需要存放在恒溫恒濕展柜中，恒溫恒濕展柜跟普通展柜的區別在與溫濕度的控制，什么是恒溫恒濕展柜的溫濕控制中高效能比
Many of the relics on display in the museum are stored in the constant temperature and constant humidity display cabinet because of its special nature, and the difference between the constant temperature and humidity display cabinet and the common display cabinet is with the temperature and humidity control, and what is the high efficiency ratio in the temperature and humidity control of the constant temperature and constant humidity display cabinet.
在傳統的恒溫恒濕空調系統設計中，在溫度和濕度的控制上，機組有風冷和水冷型兩種，配備有多級電加熱器和電極加濕罐及微電腦控制器。在冷卻祛濕工況條件下，蒸發盤管使空氣溫度低于露點溫度而去濕，通過加熱器的再熱控制室內溫度保持在設定值。該類機組由于冷量的調節一般僅二檔或三檔，機組出口空氣的露點溫度不易穩定，對室內相對濕度的控制能力較低，一般宜用于相對濕度控制精度在±5%的試驗室，目前大多采用了該種定型產品。
In the design of the traditional constant temperature and constant humidity air conditioning system, in the control of temperature and humidity, the unit has two kinds of air cooling and water cooling, equipped with multistage electric heater and electrode humidifying tank and microcomputer controller. Under the condition of cooling and humidifying, the evaporating coil makes the air temperature lower than the dew point temperature, and the temperature of the heater is kept in the set value by the reheat of the heater. This kind of unit is usually only second or third gear due to the adjustment of cooling capacity. The dew point temperature of the air of the unit is not easy to stabilize, and the control ability of the relative humidity in the room is low. Generally, it should be used in the test room with the precision of relative humidity control in 5%. At present, most of this type of product is used.
簡單來說就是冷卻、加溫、除濕的過程。雖然效果比較明顯，但是很顯然這個過程的當中的空調能耗會比較大，尤其在濕度比較高的環境下，既要保證除濕的效果，又要保證預設的溫度，此時的耗能量將遠遠大于一般機房空調的耗能量。
Simply speaking, it is the process of cooling, heating and dehumidification. Although the effect is obvious, it is clear that the air conditioning energy consumption in this process is relatively large, especially in the high humidity environment, not only to ensure the effect of dehumidification, but also to guarantee the temperature of the preset, at this time the energy consumption will be far greater than the energy consumption of the air conditioning in the general machine room.
為了避免這種情況，再設計上可以將室外空氣處理到機器露點再同室內回風混合，進入主空調箱干冷卻送風，把送風溫差控制在相應的規范范圍內；直到環境內冷負荷減小至一定數值，再用冷卻盤管的冷凍水流量或進水溫度的改變來調節冷量，進一步減小送風溫差。在這類空調工程設計中，應該對其能耗和節能問題給予特別重視，提倡棄用二次加熱，以降低能耗
In order to avoid this, the outdoor air can be treated to the dew point of the machine and then mixed with the indoor air return, into the dry cooling air of the main air conditioner, and control the air temperature difference within the corresponding standard range, until the cooling load in the environment is reduced to a certain value, and then the cooling water flow or the inlet temperature of the cooling coil is used. Change to adjust the cooling capacity, and further reduce the air temperature difference. In this type of air-conditioning design, special attention should be paid to its energy consumption and energy saving, and two heating should be abandoned to reduce energy consumption.
