Specific implementation mode
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application are clearly and completely described, it is clear that described embodiment is only
The embodiment of the application part, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
The every other embodiment that member is obtained without making creative work should all belong to the model of the application protection
It encloses.
It should be noted that the term " comprising " in the description and claims of this application and above-mentioned attached drawing and " tool
Have " and their any deformation, it is intended that cover it is non-exclusive include, for example, containing series of steps or unit
Process, method, system, product or equipment those of are not necessarily limited to clearly to list step or unit, but may include without clear
It is listing to Chu or for these processes, method, product or equipment intrinsic other steps or unit.
Air-conditioner outdoor unit refrigerant heating device is as shown in Figures 1 to 3, includes the sealing control of copper pipe structure 1, heat tape end
Box 2, heat tape 3 and the band-like temperature sensor of hard processed and control box 4.
Electrical heating module diagram is as shown in figure 4, the mounting groove 5 of the band-like temperature sensor of hard is arranged outside copper pipe structure
Portion, the band-like temperature sensor of hard and control box 4 are fixed on the positioning by mounting groove 5 on copper pipe and heat tape 3.
Heat tape 3 is wound outside copper pipe structure 1, between copper pipe structure 1, heat tape 3 and the band-like temperature sensor of hard
For blind-mate.When refrigerant passes through copper pipe structure 1, copper pipe structure 1 is heated by heat tape 3, the copper pipe after heating
Structure 1 transfers heat to refrigerant by way of heat transfer, while the high temperature refrigerant for absorbing heat enters system and recycled.
In addition to being provided with power circuit and the on/off electric control of heat tape in heat tape end part seal control box 2
Device is additionally provided with moisture seal button in heat tape port, which is similar to bottle cap；In moisture seal button and electrical heating band edge
Humidity sensor is set between face, in the season (such as summer) for not needing the work of refrigerant heating device, humidity sensor detection
Humidity, and the on/off electric controller of heat tape is fed back to, when humidity is more than the 80% of the threshold values allowable of selected heat tape
