Low-temperature and low-humidity type air conditioner device

Abstract

The invention discloses a low-temperature and low-humidity type air conditioner device. The low-temperature and low-humidity type air conditioner device comprises a compressor, a condenser, a condensation fan, a liquid storage device, a first throttling element, a second throttling element, a first evaporator, a second evaporator, an evaporation fan, a gas-liquid separator, a plurality of temperature sensors, a pipe system and the like, wherein the first evaporator and the second evaporator each are composed of a supercooling pipe group and an evaporation pipe group, the supercooling pipe groups are correspondingly and evenly distributed in the middles of the evaporation pipe groups, an outlet of the liquid storage device is divided into two paths, the first path sequentially passes through the supercooling pipe group of the second evaporator, the first throttling element and the evaporation pipe group of the first evaporator to reach the gas-liquid separator, and the second path sequentially passes through the supercooling pipe group of the first evaporator, the second throttling element and the evaporation pipe group of the second evaporator to reach the gas-liquid separator. During work, the first evaporator and the second evaporator work alternately by controlling the first throttling element and the second throttling element. By the adoption of the unique design, the low-temperature and low-humidity type air conditioner device can be widely applied to multi-stage refrigeration air conditioner projects.

Description

technical field [0001] The invention relates to the field of special refrigeration equipment, in particular to a low-temperature and low-humidity air conditioner. Background technique [0002] With the rapid development of special refrigeration equipment, there are more and more environmental guarantee requirements for special cabins. For example, the air supply temperature of air conditioners is required to be lower and lower, and the temperature and humidity fluctuation range requirements are smaller and smaller, which brings refrigeration. Various changes in the scheme lead to oversized equipment and complicated electronic control scheme. [0003] At present, most of the refrigeration schemes used in aircraft air-conditioning vehicles and cylinder-supported air-conditioning vehicles adopt the fresh air multi-stage refrigeration method, which cools the air with high temperature and high humidity (such as dry bulb temperature 40°C and relative humidity 60%) in stages. The ...
