Embodiment 1

[0073] In this embodiment, there are two inlet and outlet pipes (lower left end and lower right end), all of which are arranged at the bottom of the liquid storage tank (such as figure 1 shown); during heating or defrosting, the refrigerant flows in from the lower left end and flows out from the lower right end (such as figure 2 shown); during refrigeration, the refrigerant flows in from the lower right end and flows out from the lower left end (such as image 3 shown).

Embodiment 2

[0075] In this embodiment, there are three inlet and outlet pipes (lower left end, lower right end and upper end), wherein the lower left end and the lower right end are arranged on the bottom of the liquid storage tank, and the upper end is arranged on the top of the liquid storage tank (such as Figure 4 shown); during heating, the refrigerant flows in from the lower left end and flows out from the lower right end (such as Figure 5 shown); during defrosting, the refrigerant flows in from the lower left end and flows out from the upper end (such as Figure 6 shown); during refrigeration, the refrigerant flows in from the lower right end and flows out from the lower left end (such as Figure 7 shown). During heating (when the device is powered on) or during defrosting, the refrigerant can also flow in from the lower left end and flow out from the lower right end and upper end simultaneously.

Abstract

The invention provides a refrigerant heating device and an air conditioner. The refrigerant heating device comprises a liquid storage tank (1), an inlet pipe (2), an outlet pipe (3) and a heating component (4), wherein the liquid storage tank (1) is arranged in a vertical direction; the inlet pipe (2) is connected with the liquid storage tank (1) and communicates with the interior of the liquid storage tank (1), and refrigerant can be introduced into the liquid storage tank (1) through the inlet pipe (2); the outlet pipe (3) is connected with the liquid storage tank (1) and communicates with the interior of the liquid storage tank (1), and the refrigerant in the liquid storage tank (1) can be output through the outlet pipe (3); and the heating component (4) is arranged on the liquid storage tank (1) and is located in a position of the vertical lower part of the liquid storage tank (1). By adopting the refrigerant heating device, local overheating generated by overtemperature of gaseousrefrigerant which is heated can be prevented and avoided, the conditions of system blockage caused by decomposition and coking of lubricating oil and short service life of the air conditioner are prevented, the uniform heating degree of the refrigerant is increased, and the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a refrigerant heating device and an air conditioner. Background technique [0002] The defrosting heat of the existing heat pump air-conditioning system mainly comes from the work done by the compressor. If the indoor fan is running during the defrosting period, the defrosting heat will be blown into the room for heating, thereby weakening the defrosting ability. [0003] In order to solve this problem, the patent application number CN201210115635.7 discloses a refrigerant heating device. The device is composed of a shell, an electric heating tube and a refrigerant inlet pipeline; the shell is provided with a refrigerant inlet, a refrigerant outlet, and an electric heating tube installation port; the electric heating tube extends into the inner cavity of the shell through the electric heating tube installation port , The power terminal of the electric heatin...
