Enthalpy difference laboratory based on temperature and humidity independent controlling

Abstract

The invention discloses an enthalpy difference laboratory based on temperature and humidity independent controlling. The enthalpy difference laboratory is internally provided with a humidity adjusting system and a temperature adjusting system which are mutually independently controlled. The humidity adjusting system comprises a solution humidity adjusting air conditioner unit, and the temperature adjusting system comprises a heater. The solution humidity adjusting air conditioner unit and the heater are connected with a computer, and the computer is further connected with a temperature sensor and a humidity sensor which are arranged in the enthalpy difference laboratory. Compared with a method for adjusting the indoor temperature and humidity of a traditional enthalpy difference laboratory, the enthalpy difference laboratory based on temperature and humidity independent controlling has the advantage that the energy-saving effect is remarkably achieved, unnecessary energy source waste caused by cold and hot counteracting is omitted, the control logistic and the control process are simpler, and the adjusting speed is high.

Description

technical field [0001] The invention relates to the technical field of enthalpy difference laboratory, in particular to an enthalpy difference laboratory based on independent control of temperature and humidity. Background technique [0002] China is the world's largest producer and second largest consumer of refrigeration and air-conditioning equipment. In 2003, the country implemented a production license system for the refrigeration and air-conditioning industry, requiring manufacturers to have product performance testing devices. It may reduce the energy consumption of the experiment, which has practical significance. [0003] The enthalpy difference laboratory is a common laboratory for testing the performance of air conditioners. When the current enthalpy difference laboratory measures the performance of air conditioners, refrigeration units, electric heating, and electric humidification are usually used to make the temperature and humidity of the room meet the accura...

AI Technical Summary

Problems solved by technology

[0005] 1. High energy consumption

Since the air needs to be treated to be lower than the air supply point requirements through refrigeration and dehumidification first, and then the temperature meets the air supply requirements through electric heating, and the humidity meets the air supply requirements through electric humidification. The heating capacity of electric heating and electric humidification is used for Offset the excess cooling capacity of the refrigeration unit, wasting a lot of energy;

[0006] 2. Slow adjustment speed

The air must go through three steps of cooling and dehumidification, heating and humidification, and the control and adjustment steps are complicated
