Preferably, described heat pipe circuit can be one or more groups, and being provided with that one group of heat pipe circuit can reach can be antifreeze, and effect that again can cold air distribution is provided with many group heat pipe circuit and can makes heat exchange effect better.
Preferably, the working media in the described heat pipe circuit is any of R134a, R13, R22, R407c, and the condensation temperature of aforementioned working media is low, can also can select the low working media of other condensation temperatures for use in operate as normal under the low temperature environment.
Preferably, also comprise pressure fan, accelerate air supply velocity.
Preferably, also comprise one or more levels filter, to entering the outdoor new wind of air-conditioning unit, carry out filtration treatment, remove airborne impurity, the multistage filtering device is concentrated and is arranged on the place in the air-conditioning unit or is distributed in many places, can make filtration treatment more thorough, the air of sending is cleaner.
Preferably, also comprise humidifier, the air that enters in the air-conditioning unit is added wet process, make the humidity of sending air suitable.
Preferably, also comprise muffler, reduce the noise that unit operation brings.
Preferably, also comprise sterilizer, to entering the air disinfection in the air-conditioning unit.
Compare with existing air-conditioning unit, the utlity model has following advantage with operation antifreeze function:
The utility model is owing to be provided with heat pipe circuit before and after heat(ing) coil, the evaporation of under the evaporimeter hot environment, absorbing heat of the inner working media that fills of heat pipe circuit, heat release condensation under the condenser low temperature environment, because working media can form inner loop between evaporimeter and condenser, self can finish heat from evaporation ends to the transfer of condensation end and do not need external force, this makes the transfer of heat of high temperature gas flow of heating tube dish air side give the air-flow of inlet side as preheating, thereby improve the EAT of heat(ing) coil, can realize the antifreeze effect of air conditioner unit in winter operation, also can reduce the wind pushing temperature of air-conditioning unit simultaneously, and conserve energy, simple in structure, need not safeguard, cost is low.
