Temperature control and humidity box
The refrigeration cycle adopts an inverse card cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the consumed work causes the exhaust gas temperature to rise. The refrigerant is then isothermally exchanged with the surrounding medium via a condenser to transfer heat to the surrounding medium. After the refrigerant is adiabatically expanded by the shut-off valve, the temperature of the refrigerant is lowered. Finally, the refrigerant absorbs heat from the higher temperature object isothermally through the evaporator, so that the temperature of the object to be cooled is lowered. This cycle is repeated to achieve the purpose of cooling.
Temperature control and humidity box
The refrigeration system is designed with energy adjustment technology to ensure the normal operation of the refrigeration unit, and to effectively adjust the energy consumption and cooling capacity of the refrigeration system to keep the refrigeration system in optimal operation. Balanced temperature regulation (BTC) is adopted. When the refrigeration system is in continuous operation, the control system controls the output of the heater according to the result of the PID automatic calculation output according to the set temperature point, and finally achieves a dynamic balance.Kids sleep headphones, specially designed for children, made of soft fabric, built-in speaker, cover your eyes while sleeping, fixed with Velcro.It connects the phone, playing music, and let you relax, help to sleep.The shape can be customized, it can be a unicorn, crocodile, chicken, duck, cow, etc., cute shape, loved by children.
