functions of heat pump high-temperature dehumidifier:
1. Heat pump high temperature dehumidification the machine has the functions of temperature rising, dehumidification and fast drying, beautiful product appearance, fast installation, control system using German < / span > PLC touch screen control (485 communication), computer automatic setting control dehumidification and heating, control system operation is convenient and simple.
2. The equipment adopts the temperature and humidity sensor imported from Japan Shenrong, which has the advantages of long service life, good stability, high linearity, wide temperature and humidity measurement and control range, high resolution, and can also be connected with microcomputer to realize centralized monitoring.
3. The product has stable performance and reliable quality. The imported fully enclosed scroll compressor is also selected for the compressor. Compared with the piston compressor, it has less vulnerable parts, strong liquid compression resistance and temperature regulation.
4. Adopting the international famous brand Dajin compressor, the equipment has the characteristics of stable operation performance, low noise, low energy consumption, large dehumidification capacity and excellent refrigeration effect.
5. It adopts humanized design control, optimizes energy saving, and has high operation efficiency. It is equipped with antifreeze, oil pressure protection, overload protection and three minute delay protection of compressor, which ensures safe and stable operation.
6 energy saving, purification and high temperature dehumidifier has multiple functions, and the temperature can be set freely. When the environment is in a low temperature and high humidity environment, the equipment temperature will automatically run in the heating and dehumidification mode; when the indoor temperature reaches the set requirements, the equipment temperature rise mode will automatically stop working.
7, high temperature dehumidifier is the principle of direct expansion dehumidification for indoor air. The wet air is filtered into the equipment by the fan through the filter screen, and the water in the air is condensed into water through the exchanger. The dry high temperature and low humidity air is discharged to the outdoor by the water pipe through the water pan. After the dehumidification treatment, the dry high temperature and low humidity air is sent to the warehouse for recycling, so as to achieve the effect of rapid drying and dehumidification.
Equipment selection requirements:
Drying room project:
L according to the parameters and requirements provided by customers, the voltage is 380V / 50Hz
L equipment use area: (the influence of local annual temperature and humidity variation range shall be considered)
L indoor volume of drying oven: 35m3
L surface temperature requirement of heated workpiece: 55 ± 10 ° C
L indoor humidity requirement: within 20%
L air supply outlet humidity ≤ 12%
L the air supply outlet can set the air supply temperature, and the temperature setting interface is required. The setting temperature range is 40 ~ 65 ° C
L temperature fluctuation range of air supply outlet: t ± 5 ° C (t is set temperature)
L air supply is required to raise the room temperature from normal temperature to 40 ℃ within 15 minutes
L the recovery time is less than 90s (under the constant temperature of 40 ℃, the opening time shall not exceed 1 min, and the time to recover to 40 ℃ after closing the door)
L timing control: 120 ~ 420s
L it has reliable overheat protection mode and clearly indicates the mode content
(if the temperature sensor is set after the electric heating, the PLC detects the temperature of the sensor, if the temperature exceeds the set temperature, stop the electric heating)
Main heating circuit: air switch + contactor + solid state relay / voltage regulator + heating element
Among them, Schneider brand is selected for air switch and contactor, and Goode brand is selected for solid state relay / voltage regulator
The control system can read, monitor and set the air outlet temperature and humidity of the equipment
L the central control system adopts the components of Lefu brand
L the main program of central control PLC is open for editing. If there is parameter algorithm and other confidential content, Party B can write it into function block / function / subroutine for encryption, but digital IO and analog read-write interface shall be opened
L touch screen program is open, which can facilitate the development of new functions
L 20% - 30% space reserved for electric control cabinet
L equipment noise ≤ 65dB
Dehumidification calculation
Dehumidification calculation formula: D = ρ V (d1-d2) / 1000
Note: D - wet load Λ - air density V - air volume
D1 - ambient moisture content D2 - supply air moisture content
