Energy-saving enthalpy difference laboratory

Abstract

According to an energy-saving enthalpy difference laboratory provided by the invention, through the design of a barrel pump refrigeration system, the evaporation temperature of 15 DEG C or above can be formed on a first evaporator and a second evaporator, so that under the working conditions of high temperature and high humidity, the refrigeration system cannot spontaneously generate redundant dehumidification, and the excessively low air humidity can be prevented, thereby avoiding a large amount of humidification compensation; when the outdoor temperature is low, different evaporation temperatures can be formed indoors and outdoors for cooling through a liquid storage barrel; meanwhile, the room is subjected to heating regulation through heat of a second condenser and a third condenser, so as to take the heat recovery effect and avoid investment of electric heating; and by ultrasonic humidifiers on the indoor side and the outdoor side, the problem of redundant heat of electric humidification is avoided according to the principle of isenthalpic humidification, and the energy-saving effect of the laboratory is greatly improved.

Description

technical field [0001] The invention relates to an energy-saving enthalpy difference laboratory. Background technique [0002] In the refrigeration system of the existing air-conditioning laboratory, the evaporation temperature of the evaporator is often low, generally below 15°C. Since this temperature is much lower than the dew point temperature of the air, the refrigeration system will spontaneously generate redundant dehumidification of the air, making the temperature in the laboratory The air humidity is too low. When the test room needs to be tested under high temperature and high humidity conditions, a large amount of electric heating and electric humidification are required to balance the working conditions, which makes the energy consumption of the test room high, especially when the humidification is brought into redundancy. Even more so when it comes to heat. In addition, the existing air-conditioning laboratory refrigeration system has a small temperature contro...

Even more so when the heat

In addition, the existing air-conditioning laboratory refrigeration system has a small temperature control range and cannot freely switch between low-temperature cycle and high-temperature cycle, which cannot meet the needs of various working conditions in the laboratory.
