Pressure control type air energy water heater and control method

Abstract

The invention discloses a pressure control type air energy water heater, which comprises a compressor, a four-way valve, a first heat exchanger and a second heat exchanger, wherein the compressor comprises a high-pressure air outlet and a low-pressure air inlet; the four-way valve comprises a connecting port A, a connecting port B, a connecting port C and a connecting port D; a heat exchange pipe is arranged on a pipeline between the high-pressure air outlet of the compressor and the connecting port A; and the heat exchange pipe comprises a first pipe fitting and a second pipe fitting which sleeves the first pipe fitting. A control method of the pressure control type air energy water heater is that an independent water heating mode, a water heating and air cooling mode, a water heating and air warming mode, an independent air cooling mode and an independent air warming mode are switched. The pressure control type air energy water heater and the control method have the advantages that the heating speed is rapid; electric energy is saved; the pipeline pressure is stable; and the operation is smooth and the like; and the pressure control type air energy water heater can independently operate among the water heating function, the air cooling function and the air warming function, and the three functions are freely switched and mutually combined, so convenience and practicability are realized.

Description

technical field [0001] The invention relates to a pressure-controlled air energy water heater and a control method. Background technique [0002] When the existing air-energy water heater operates in multiple modes such as independent hot water, hot water and cold air, hot water and heating, independent cooling, independent heating, etc., due to the uneven pressure of the internal pipeline, it is easy to appear. The air pressure of some pipelines is too high or too low, which makes the air source water heater easy to stop when it is running, and it is prone to failure, which increases maintenance costs and reduces service life. When the current air energy water heater realizes the functions of water heater and air conditioner at the same time, the water heater function and the air conditioner function cannot be completely independent. The water heater function can only be performed when the air conditioner function has been turned on. Only when two functions are turned on c...

[0002] When the existing air-energy water heater operates in multiple modes such as independent hot water, hot water and cold air, hot water and heating, independent cooling, independent heating, etc., due to the uneven pressure of the internal pipeline, it is easy to appear. The air pressure of some pipelines is too high or too low, which makes the air energy water heater easy to stop when it is running, and it is prone to failure, which increases maintenance costs and reduces service life

When the current air energy water heater realizes the functions of water heater and air conditioner at the same time, the water heater function and the air conditioner function cannot be completely independent. The water heater function can only be performed when the air conditioner function has been turned on. Only two functions can be turned on, which brings great inconvenience to the user, wastes electric energy, increases the failure rate of the air energy water heater, and reduces the service life
