目前，食品冷库建立温度控制主要采用了蒸汽压力控制、电子控制两种，其中电子式温度控制器主要应用在我国的小型食品冷库建立和空调温度控制。控制器介绍：
At present, the establishment of food cold storage temperature control mainly uses the steam pressure control, electronic control two kinds, in which the electronic temperature controller is mainly used in the establishment of small food cold storage and air conditioning temperature control. Controller introduction:
1.电子式温度控制器是采用了电阻式温度感应来停止温度控制的，电阻式温度控制适合使用在小型的环境里，以铜丝和钨丝为最主要的电阻，目前最先进的是电子式温度控制器都采用了可编顺序控制，用户可以同通过自定义温度来控制最佳的制冷温度。

Electronic temperature controller is the resistive temperature sensor to stop temperature control, resistance type temperature control is suitable for use in the environment of the small, the main resistance to copper and tungsten, the most advanced is electronic temperature controller using the programmable logic control, the user can through custom temperature to control the optimum refrigeration temperature.

2.蒸汽压力式温度控制器一种通过波纹管来停止温度开关的装置。在空调机的入风口出设置毛细管，当室内温度发作变化，温度到达设定值的时候，毛细管就会收到感温计的影响，迅速的收缩，当收缩到一定的体积的时候就会接通开关，这个时候压缩机通过对温度的判别，就会自动停止制冷，当温度下降，感温剂就会受冷，毛细管就会逐渐的收缩，当收缩到一定水平的时候，就会断开开关，压缩机就会停止重复的制冷制热任务，里外控制整个环境的温度。
2.the steam pressure type temperature controller is a device that stops the temperature switch through the bellows. In air conditioner into the air inlet arranged capillary, happens when the indoor temperature changes, temperature reaches the set value, capillary will receive thermometer effect, rapid contraction, when the contraction to a certain volume when will be connected to the switch, the compressor through the discrimination of the temperature, it will automatically stop refrigeration, when the temperature drops, the temperature sensing agent will be affected by the cold, capillary will gradually shrink, when the contraction to a certain level, it will break open switch, compressor will stop repeated cooling and heating task, inside and outside the control of the temperature of the environment.
家庭中常用的冰箱冰柜等的温度控制原理就有些不同，冰箱使用的温度控制器是由一个犯规电路和比较器组成的，在温度设置好之后，会用温敏电阻测量箱内温度，当高于设定温度时,会加大功率,增强迫冷,反之减小；这样一直作用，就会使之到达设定温度。这种温度控制原理，主要适应在冰箱和冰柜的使用用。
Commonly used in the family fridge freezers and other temperature control principle is somewhat different, the refrigerator temperature controller is composed of a foul and a comparator circuit, the temperature set, with a temperature sensitive resistor measuring the temperature inside a box. When the temperature exceeds the preset, increasing work rate, enhance the forced cooling, contrary to reduce; this effect, would make the reaches the set temperature. The temperature control principle, mainly used in refrigerators and freezers for use.
