Embodiment 1

[0033] Such as figure 1 As shown, the refrigerant heating device of the present invention includes a section of refrigerant heating pipe section arranged in the refrigerant piping 1, and a protection pipe 4 sleeved on the outer surface of the refrigerant heating pipe section. The protection pipe 4 is preferably made of heat-resistant stainless steel, copper or iron, etc. made of magnetic material and / or magnetic heating material, an electromagnetic induction coil 2 is wound on the outer surface of the protection tube 4, and the electromagnetic induction coil 2 is electrically connected with the high-frequency power supply device, and is located near the refrigerant outflow end of the refrigerant piping 1 A temperature sensor 5 is provided, preferably, a high-frequency power supply device is electrically connected to the temperature sensor 5 . The high-frequency power supply device includes a main board and a high-frequency power supply. The main board receives the temperature ...

Embodiment 2

[0036] Such as image 3 As shown, on the basis of Embodiment 1, in order to improve the heating efficiency of the electromagnetic induction coil 2, a heating structure 6 is arranged in the refrigerant heating pipe section of the refrigerant piping 1. The heating structure 6 is preferably made of steel or iron, etc. Made of thermal material and / or magnetic heating material, and preferably the heating structure 6 is composed of a plurality of dispersed stainless steel wires or iron wires, preferably, the stainless steel wires and iron wires are cylinders.

Embodiment 3

[0038] Based on the second embodiment of the present invention, in order to prevent the high-frequency power supply from adjusting the power output too frequently and to control the temperature of the refrigerant heating device, the operator pre-sets the target temperature value Tm in the high-frequency power supply device. The temperature difference between the temperature value Tm and the temperature Tn actually detected by the temperature sensor 5 is ΔT=Tn−Tm.

[0039] According to the actual heating needs of the refrigerant, set the temperature t 1 is the upper critical heating temperature, t 2 is the lower critical heating temperature, where 0℃1 ≤1℃, -1℃≤t 2 <0°C. Set the following control logic in the main board of the high-frequency power supply unit:

[0040] 1) When ΔT≥t 1 When , the high-frequency power supply reduces the output power;

[0041] 2) when t 2 1 , the output power of the high-frequency power supply remains unchanged;

[0042] 3) When ΔT≤t 2 ℃, th...

Abstract

The invention provides a refrigerant heating device and an air conditioner comprising the same. The refrigerant heating device comprises a refrigerant heating pipe section which is arranged inside a refrigerant pipe, wherein the refrigerant heating pipe section comprises a refrigerant incoming end and a refrigerant outgoing end and is made of magnetic heating materials, and an electromagnetic induction coil is twined round the outside of the refrigerant heating pipe section and is electrically connected with a power supply device. According to the refrigerant heating device, the electromagnetic induction coil which is connected with the power supply device is twined round the refrigerant heating pipe section, so that a refrigerant can be heated; by the aid of electromagnetic heating, the processing technology is simple, electricity can be completely isolated from the refrigerant, electrical safety problems such as overheating and circuit breakdowns are solved, and electrical safety and reliability are guaranteed.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a refrigerant heating device and an air conditioner including the device. Background technique [0002] When the air conditioning and refrigeration system operates at low temperature, the evaporation and heat transfer capacity of the refrigeration system is poor, the refrigerant cannot evaporate completely, and cannot absorb enough heat, which leads to poor cooling effect of the air conditioner, frosting or freezing of the evaporative heat exchanger, and compressor suction. Therefore, it is difficult to guarantee the cooling effect and reliability of the air conditioner. [0003] The utility model patent with the notification number CN201314734Y discloses a refrigerant electric heating device, which not only has complicated processing technology, but also cannot control the surface temperature of the heating element when the state of the refrigerant (such as flow rate, temperature...
