Preposed nano enthalpy-increasing device of heat pump

Technical Field

The invention relates to heat pump equipment, in particular to enthalpy increasing equipment of a heat pump.

Background

The heat pump is usually adopted to produce a heat source, the working environment temperature of the heat pump cannot be too low, Freon cannot be completely vaporized if the environment temperature is too low, liquid microbeads exist, the compressor cannot normally work due to the microbeads, the phenomenon is also called the liquid impact phenomenon of the compressor, the efficiency of the compressor is greatly reduced due to the liquid impact phenomenon, and the operation of the heat pump in a low-temperature environment is influenced.

Disclosure of Invention

In order to enable a heat pump machine to work normally at a low temperature, the problem of incomplete vaporization of Freon must be solved, and in order to solve the problem, a method of heating on a gasification channel is adopted to solve the liquid impact phenomenon.

In a heat pump system, in a heat pump compressor, one end of the compressor is a high-pressure liquid state freon output end, and the other end of the compressor is a low-pressure gas state freon input end, and the gas state freon is properly preheated at the low-pressure input end of the compressor, so that liquid microbeads in the gas state freon entering the compressor are completely vaporized, and the work of the compressor is not influenced.

A heat pump preposed nano electric heating enthalpy-increasing device is characterized in that an electric heating preheating device is arranged at the input end of a compressor, so that Freon steam flowing through the compressor is heated by the electric heating preheating device before entering the compressor, and the Freon steam is completely vaporized. The electric heating preheating device is a nano electric heating film wound on the air guide tube, the electric heating film is electrified to heat the air guide tube, freon steam flowing through the air guide tube can be heated, and in addition, a method of heating in the tube can be adopted, so that the effect is better. The method of heating in the pipe is that an electric heating pipe is additionally arranged between an input port of a compressor and an air guide pipe, the electric heating pipe is a pipe with a nano electric heating cone inside, the bottom opening of the cone is aligned with the air flow direction, Freon steam is shot to the cone at a high speed, the steam can turn around the cone in the cone due to being lighter, and liquid microbeads mixed in the Freon steam can collide against the hot cone wall due to the fact that the liquid microbeads are heavier than the steam, the microbeads can be changed into steam on the cone wall, the electric heating nano cone can well remove the liquid microbeads in the Freon steam, so that the compressor can avoid impact of liquid impact and work in a normal state.

A heat pump preposed nano electric heating enthalpy-increasing device is characterized in that two ends of the heat pump preposed nano electric heating enthalpy-increasing device are provided with a pipe with a connecting port, a cone without a bottom is arranged in the pipe, the bottom of the cone faces to a pipe opening, nano electric heating materials are coated on the cone, two electrodes are led out from the pipe wall on the cone, insulators are arranged between the pipe wall and the electrodes for isolation, the inner diameter of the cone is smaller than that of the pipe, the cone is suspended in the pipe, one end of the pipe is connected with an input port of a compressor, the other end of the pipe is connected with an air guide pipe, and the bottom of.

Detailed Description

As shown in figure 1, in the system with a heat pump preposed nano electric heating enthalpy-increasing device, the nano electric heating enthalpy-increasing device is arranged on an input port of a compressor and then is connected with an air duct, two electrodes of the nano electric heating enthalpy-increasing device are connected with commercial power, and when the environmental temperature is particularly low, the nano electric heating enthalpy-increasing device needs to be electrified to work.

Fig. 2 is a structural diagram of a nano electric heating enthalpy-increasing device, when the nano electric heating enthalpy-increasing device is electrified to work, freon steam is sprayed to the bottom of a cone at a high speed under the action of a compressor, the steam can turn around the cone in the cone to enter the compressor due to light mass of the steam, liquid microbeads contained in the freon steam have large momentum due to heavy mass, and the liquid microbeads can directly impact on the wall of the cone and then are heated to be changed into steam, and then the steam is sucked by the compressor, so that the freon steam does not contain the liquid microbeads after being filtered by the cone, the impact and the damage of the liquid microbeads on the liquid impact phenomenon of the compressor are thoroughly avoided, the compressor can normally work at a very low ambient temperature, and the working efficiency of the compressor is greatly improved.
