Temperature control device of plate processor solution

Abstract

A temperature control device of a plate processor solution comprises a solution tank for bearing the solution, a refrigerant pipe type heat exchanger arranged in the solution tank, a compressor, a heat exchanger and a temperature control device. The temperature control device is characterized in that an intermediate heat exchanger is arranged, and the intermediate heat exchanger comprises a freezing water tank and an intermediate refrigerant pipe type heat exchanger arranged in the freezing water tank. Compared with the prior art, the temperature control device has the advantages that the temperature control requirement for less needed cold energy per unit of time can be met, the temperature control requirement for much needed cold energy per unit of time can further be met, and temperature control is precise.

Description

Technical field: [0001] The invention relates to a printing device. Background technique: [0002] Existing temperature control devices for plate processing liquid medicine generally include a liquid medicine tank carrying liquid medicine, a refrigerant pipe heat exchanger arranged in the liquid medicine tank, a compressor, an air-cooled heat exchanger, a temperature control device, and a refrigerant pipe heat exchanger. The medium outlet of the exchanger is connected to the inlet of the compressor, the outlet of the compressor is connected to the medium inlet of the air-cooled heat exchanger, and the medium outlet of the air-cooled heat exchanger is connected to the medium inlet of the refrigerant tube heat exchanger through the evaporator Connected, the temperature control device controls the work of the compressor according to the temperature measured by the temperature sensor in the liquid medicine tank. With this kind of temperature control technology, since the power ...

AI Technical Summary

Problems solved by technology

With this kind of temperature control technology, since the power output per unit time of each operation of the compressor is basically unchanged, the cold energy produced per unit time is also basically unchanged, and the temperature change of the liquid medicine tank is uncertain, sometimes It is relatively large, and sometimes it is relatively small. If a compressor with a small cooling energy manufactured per unit time is used, when the temperature of the liquid medicine tank changes greatly and a large cooling energy is required in a short period of time, the compressor with a small cooling energy cannot meet the requirements. Requirements; and the compressor with large cooling energy manufactured per unit time, when the temperature change of the liquid medicine tank is small and needs small cooling energy to adjust in a short time, the compressor with large cooling energy is easy to supply due to the large cooling energy and cause the temperature of the chemical tank to change beyond the required control range
