Temperature adjusting system for closed heating space under full work conditions

Abstract

The invention discloses a temperature adjusting system for closed heating space under full work conditions. The temperature adjusting system for closed heating space under full work conditions comprises a refrigerating system, a ventilating system, a heating system and an electronic control system, wherein the refrigerating system comprises a compressor, a condenser, a liquid storage device, a filter, an expansion valve and an evaporator; the ventilating system comprises an air return system, a fresh air inlet system, an exhaust system, an evaporation fan, a condensing fan and closed space; the heating system comprises an electric heating device; the electronic control system comprises a control unit and a protecting system; and the protecting system comprises a temperature sensor A and a temperature sensor B. The temperature adjusting system for closed heating space under full work conditions has the characteristics of simple structure, easiness in implementation, small numbers of equipment and assemblies, high efficiency, low cost, convenience in repair and high efficiency, can normally work in an environment at the temperature of minus 45-60 DEG C, can refrigerate to cool circularly under the condition that the environment temperature is high, can circularly cool in an air-cooled manner under the condition that the environment temperature is relatively low, and can heat under the condition that the temperature is low.

Description

technical field [0001] The invention relates to the technical field of air conditioning for air conditioning equipment, in particular to a temperature regulating system for a closed heating space under all working conditions. Background technique [0002] Due to its high efficiency, high reliability, low cost, energy saving and many other advantages, the temperature regulation system of the closed heating space under all working conditions has become the first choice for the temperature regulation of the closed space with special high heat generation. Based on the development of the special high-power electronic heating equipment industry At present, many special high-power electronic heating equipment need to adjust the temperature in the range of full working conditions, especially in the case of low ambient temperature. The realization of temperature adjustment and other technologies within the scope of the application puts forward new requirements for the air conditionin...

AI Technical Summary

Problems solved by technology

Usually, in the case of low temperature, if the vapor compression refrigeration is still used to cool down, this kind of refrigeration requires many adjustment devices, such as setting a condensing pressure regulating valve, and adopting stepless speed regulation for the condensing and cooling fans. This method is complicated to adjust. High cooling cost, high power consumption, frequent start and stop of compressors, reduced system life, reduced reliability, etc.
