Specific implementation mode
For a further understanding of the utility model, the utility model is carried out with reference to the accompanying drawings and embodiments further detailed
It describes in detail bright.It is understood that specific embodiment described herein is used only to explain the utility model, it is not used to limit
The utility model.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of seperated refrigerator outdoor compressor cold-starting auxiliary device of the present embodiment, including pressure
Contracting machine 5,5 outside of the compressor are equipped with insulation shell 1, and the insulation shell 1 is equipped with compressor input port and compressor is defeated
Outlet, the compressor output channel are connected by insulation shell delivery outlet with the condenser 8 in outdoor machine shell, the compressor
Input channel is connected by insulation shell with evaporator in refrigerator 4, and ptc heater 2, the PTC are equipped in the insulation shell 1
2 bottom of heater is equipped with circulating fan 3.
The insulation shell 1 is made of the insulating layer filled between shell wall and shell wall.
The shell wall is metal or nonmetallic materials.
The insulating layer 6 is using pixel, the one of which of polyurethane, polyphenyl or phenolic aldehyde.
The ptc heater 2 and circulating fan 3 are controlled by PLC controller to be started.
The circulating fan 3 uses centrifugal blower or AC blower fan.
The compressor 5 uses the one of which of reciprocating compressor, rolling rotor compressor or scroll compressor.
The operation principle of the present embodiment is：The utility model use environment temperature is minimum to be started at -40 DEG C, and ring is reduced
Border temperature restraint ability, expands application range, and use has good user in such as supermarket, family, hotel, hotel etc.
Experience, shell 1 are totally-enclosed and have insulating layer 6, shell 1 wherein, to hinder compressor 5, ptc heater 2, the package of circulating fan 3
Only heat exchange is carried out with extraneous air.When compressor 5 needs to start under less than -10 DEG C environment, shell 1 inside PTC heating
Device 2, circulating fan 3 are started to work, and heat cycle in shell 1, since 1 inner space of shell is small, heater 2, cycle are generated
1 interior space temperature of shell can be heated to 0 DEG C or more by fan 3 in very short time, when compressor 5 is in 0 DEG C or more of space
When, the refrigeration oil of compressor 5 is not in condensation situation, can smoothly be started.In addition it is filled with above-mentioned material in insulation shell
Insulating layer so that the rate of heat exchange of insulation shell and outdoor cold air reduce, greatly accelerated the startup time of compressor,
It ensure that seperated outdoor unit normal operation.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the methodology of the utility model
The improvement of the various unsubstantialities carried out with technical solution, or it is not improved that the design of the utility model and technical solution is direct
Applied to other occasions, it both is within the protection scope of the present invention.
