If the temperature of external environment is higher than the temperature in the cabinet, compressor refrigeration system will start so.Compressor is the power of compressor assembly when running refrigerating, cold-producing medium enters in the condenser become the gas of HTHP through the compression of compressor after, heat release becomes the liquid refrigerant of high pressure low temperature in condenser, after becoming the low-pressure low-temperature state after the throttling arrangement throttling, enter in the evaporimeter, refrigeration machine absorbs heat and becomes gaseous medium and absorbed to finish the circulation of compressor cooling by compressor again in evaporimeter, so repeatedly.Condenser and evaporimeter to strengthen cross-ventilation, are strengthened the heat exchange effect by separately circulating fan.Wherein the heat exchange of condenser and air is carried out outside switch board, and the heat exchange of evaporimeter and air then circulates in airtight switch board and carries out.
If the temperature of external environment is lower than the temperature in the cabinet, this moment, heat-exchange system will start.In VMC, because the physical effect of medium, when temperature is hanged down cabinet outside, the medium condensation liquefy of will dispelling the heat, effect by gravity flow into the kinetic pump porch, by kinetic pump liquid medium is delivered to evaporation channel in the cabinet again, because the temperature in the cabinet is higher, satisfy the evaporating temperature of medium fully, so medium will absorb the heat in the cabinet, medium absorbs and enters condensation channel again after heat becomes gas, carries out repeatedly according to this, reaches the cooling-down effect in the cabinet.Condenser and evaporimeter to strengthen cross-ventilation, are strengthened the heat exchange effect by separately circulating fan.Wherein the heat exchange of condenser and air is carried out outside switch board, and the heat exchange of evaporimeter and air then circulates in airtight switch board and carries out.In sum, after heat-exchange system starts operation, kinetic pump produces motive force, making efficiently, cold-producing medium enters in the parallel flow condenser, because ambient temperature is low, this medium can immediately form liquid form, then in the evaporimeter in the inlet chamber, because the indoor temperature height, this medium absorbs heat at once and becomes gaseous material and suck to finish a kind of refrigeration cycle by kinetic pump again.Just need not compressor operating during heat exchanger work, can reduce energy consumption.
The fan of system sucks hot gas in cabinet, become cold gas behind the distinguished and admirable process evaporator fin and get rid of from the air channel, to reach the effect of lowering the temperature in the cabinet.And following blower fan sucks the gas the environment outside cabinet, and the gas that becomes heat behind the distinguished and admirable process condenser fin is discharged from the air channel.So form with heat from indoor to outdoor transfer.
When the temperature outside the cabinet was higher than temperature in the cabinet, control system will be closed kinetic pump, and the passage of medium will block from kinetic pump, so do not needed to worry medium the problem of dispelling the heat because the outer temperature of cabinet is higher than in-cabinet temperature in cabinet.When the temperature outside the cabinet was higher than temperature in the device, controller 12 will cut out kinetic pump, and the passage of medium will block from kinetic pump, avoided medium thus because the outer temperature of cabinet is higher than in the device temperature and dispels the heat in device.
