在博物館里很多展出的文物由于其性質(zhì)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(qū)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(tǒng)的恒溫恒濕空調(diào)系統(tǒng)設(shè)計(jì)中，在溫度和濕度的控制上，機(jī)組有風(fēng)冷和水冷型兩種，配備有多級(jí)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(fā)盤管使空氣溫度低于露點(diǎn)溫度而去濕，通過(guò)加熱器的再熱控制室內(nèi)溫度保持在設(shè)定值。該類機(jī)組由于冷量的調(diào)節(jié)一般僅二檔或三檔，機(jī)組出口空氣的露點(diǎn)溫度不易穩(wěn)定，對(duì)室內(nèi)相對(duì)濕度的控制能力較低，一般宜用于相對(duì)濕度控制精度在±5%的試驗(yàn)室，目前大多采用了該種定型產(chǎn)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(jiǎn)單來(lái)說(shuō)就是冷卻、加溫、除濕的過(guò)程。雖然效果比較明顯，但是很顯然這個(gè)過(guò)程的當(dāng)中的空調(diào)能耗會(huì)比較大，尤其在濕度比較高的環(huán)境下，既要保證除濕的效果，又要保證預(yù)設(shè)的溫度，此時(shí)的耗能量將遠(yuǎn)遠(yuǎn)大于一般機(jī)房空調(diào)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(shè)計(jì)上可以將室外空氣處理到機(jī)器露點(diǎn)再同室內(nèi)回風(fēng)混合，進(jìn)入主空調(diào)箱干冷卻送風(fēng)，把送風(fēng)溫差控制在相應(yīng)的規(guī)范范圍內(nèi)；直到環(huán)境內(nèi)冷負(fù)荷減小至一定數(shù)值，再用冷卻盤管的冷凍水流量或進(jìn)水溫度的改變來(lái)調(diào)節(jié)冷量，進(jìn)一步減小送風(fēng)溫差。在這類空調(diào)工程設(shè)計(jì)中，應(yīng)該對(duì)其能耗和節(jié)能問(wèn)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.
