Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] Such as figure 1 As shown, the automatic control device includes a storage temperature sensor, a storage temperature secondary instrument, a control circuit and a cooling fan connected in sequence, and also includes a frost temperature sensor, a frost temperature secondary instrument, a control circuit and a refrigerator connected in sequence. When the temperature sensed by the storage temperature sensor reaches the upper limit temperature set by its secondary instrument, the corresponding control circuit will start the cooling fan in the storage, and the frost temperature sensor on the evaporator of the cooling fan and its secondary instrument will start to work. When there is frost on the surface of the evaporator, the frost temperature secondary instrument stops the refrigerator through the control circuit, and the air cooler evaporator starts to defrost; If it i...

Abstract

The invention discloses a cool house instant automatic defrosting control device, which comprises a cool house temperature sensor for measuring the temperature of the cool house, a frost temperature sensor for measuring the temperature of frost on the surface of an evaporator of an air cooler, a cool house temperature secondary instrument for setting temperature bound of the cool house, a frost temperature secondary instrument for setting temperature bound of the frost, the air cooler arranged in the cool house, a refrigerator arranged outside of the cool house and a control circuit for controlling the operation of the air cooler and the refrigerator. The control device makes the evaporator of the air cooler in the cool house defrost instantly and release cooling air to the cool house, so that the cool house has no frost and high-efficiency and safe operation. The control device has the advantages of delicate and simple structure of circuits, strong operability and low failure rate.

Description

technical field [0001] The invention relates to an instant automatic frost control device for a cold storage. Background technique [0002] The current manual control and automatic control of cold storage are difficult to ensure that the evaporator in the cold storage does not accumulate frost. In order to keep the evaporator in the cold storage at a scientific and reasonable evaporation temperature, external heating is generally used for defrosting. Although this method can reduce the reduction of refrigeration efficiency and liquid shock damage to the refrigerator caused by frost accumulation on the evaporator, the storage temperature fluctuates greatly and consumes a lot of energy. Although some control devices that utilize cold storage temperature and frost temperature automatic frosting can avoid severe frost accumulation in the evaporator. However, the combination of storage temperature and frost temperature requires high technical requirements, and it is generally di...
