Description

[Detailed Description of the Invention] This invention relates to an air conditioner, and particularly to prevention of frost formation on a cooler thereof.

In general, air conditioners have a temperature controller that senses the room temperature and starts and stops the operation, and frost forms on the cooler.
It is necessary to have a temperature controller to prevent frost formation, which senses when the temperature of the cooler drops and stops the air conditioner. In some cases, a vessel serves both of the above two purposes.
However, this method is not particularly effective in preventing frost formation on the cooler.

Conventionally, in this type of anti-frost device for air conditioner coolers, when one temperature controller is used to control room temperature and prevent frost on the cooler, the first
As shown in the figure, on the surface of the cooler 1, on the windward side of the air to be cooled passing through the cooler, there are two to three
The temperature sensing part 3 of the temperature regulator 2 is provided at a distance of mm.

To explain the operation of the air conditioner configured in this way, firstly, regarding room temperature control, the temperature controller 2 provided on the surface of the cooler 1
Since the temperature-sensing section 3 of Starts and stops the harmonizer.

Furthermore, when the air conditioner is operated under low temperature conditions and frost forms on the cooler 1, the frost 4 forms and grows on the surface of the cooler 1 as shown in the cross-sectional view of FIG. The temperature sensor 3 of the temperature controller 2 senses the temperature of the frost 4 and stops the operation of the air conditioner. If the frost 4 melts when the air conditioner is stopped, the temperature sensing section 3 of the temperature controller 2 senses this and starts operating the air conditioner again. In this way, the temperature regulator 2 can prevent frosting of the cooler 1. However, in the case of this frost prevention, although it is sufficiently effective when frost 4 is uniformly generated on the cooler 1,
For example, if the path of the cooler is divided into upper and lower parts, frost will form unevenly on the upper and lower parts, and only the one with the temperature sensing part 3 of the temperature regulator 2 will sense it, so the other had the disadvantage of leaving behind frost.

This invention was made in view of these points, and is intended to sufficiently prevent frost formation even when the cooler has two or more passes.

An embodiment of this invention shown in FIG. 3 will be described below.

1 is a cooler having a path divided into upper and lower parts, and arrows indicate the flow of refrigerant. 2 is a temperature controller,
Reference numeral 3 denotes a temperature sensing part extending from this temperature regulator, which faces the windward surface of the air to be cooled of the cooler 1 having the two-divided path, and is bent into a crank shape and has two upper and lower paths. It is installed across the.

To explain the operation of the air conditioner configured in this way, the temperature control is the same as the conventional one, but in the case of frost prevention, the frost 4 is , even if it occurs only on one path, it will be detected and the air conditioner will be stopped, and while the air conditioner is stopped, the air conditioner will start operating before the frost on one path has completely melted. It is possible to sufficiently prevent frost formation without starting the process.

As mentioned above, this invention includes a temperature regulator that serves both room temperature control and frost prevention control of the cooler;
The temperature control device is composed of a cooler having a path divided into two upper and lower parts, and the temperature control device is arranged so as to face the windward surface of the air to be cooled of the cooler having two divided paths, spanning each path. Since the temperature-sensing part of the container is extended, it has the excellent effect of being able to completely control the room temperature and prevent frost on the cooler with a single temperature controller.
