Description
Technical field
The invention belongs to the air-conditioner technical field, particularly relate to and a kind ofly can keep constant distance, difficult drop-off or displacement, defrosted less, heat the temperature sensor fixing structure of the air-conditioner outdoor unit that running influences with condenser.
Background technology
In general, air-conditioner makes refrigerant and indoor flow air carry out heat exchange to realize indoor cooling, intensification or air cleaning, for people provide fresh, comfortable air ambient by its coolant circulating system and air circulation system.The coolant circulating system of air-conditioner mainly by compressor, reversal valve, condenser, expansion valve, evaporimeter, etc. parts form.
Air-conditioner can roughly be divided into the package AC plant that detachable air conditioner that off-premises station and indoor set be provided with respectively and off-premises station and indoor set are wholely set.
Be provided with parts such as compressor, condenser, outdoor fan, expansion valve and control box in the off-premises station of detachable air conditioner.The off-premises station inner space is by the dividing plate separated into two parts, the secondary space that the principal space of condenser and outdoor fan promptly is set and parts such as compressor, expansion valve and control box are set.Dividing plate is used for being provided with and installing expansion valve and control box.
When detachable air conditioner carries out refrigerating operaton, compressor in the off-premises station is compressed into the gaseous coolant of low-temp low-pressure high-temperature high-pressure state and sends into condenser, the gaseous coolant of HTHP carries out heat exchange with outdoor fan forced circulation flow air in condenser, warm highly pressurised liquid state in being cooled into.Behind the absorption of air heat in the off-premises station, temperature raises and is discharged in the external environment.The liquid refrigerants of warm high pressure is through expansion valve decompression cooling in being cooled into, and its temperature and pressure all drops to original low-temp low-pressure state.The liquid refrigerants of low-temp low-pressure enters the evaporimeter in the indoor set again, and carries out heat exchange with room air that the indoor fan forced circulation flows.In the evaporimeter in the refrigerant absorption chamber of low-temp low-pressure state airborne heat become gaseous state by liquid state, the refrigerant after the gasification carries and enters condenser again after heat in the room air that is absorbed returns the compressor in the off-premises station again and is compressed into high-temperature high-pressure state again and circulate successively ...
Like this, detachable air conditioner is by being circulated in the refrigerant in compressor, indoor machine evaporation and the outdoor condenser, and the circulating air with indoor and outdoors carries out the heat exchange circulation respectively, is reached for the purpose of room air refrigeration.
Fig. 1 is general air-conditioner outdoor unit STRUCTURE DECOMPOSITION figure.
