Double-heating and one-evaporation gas-liquid tank type multifunctional energy-saving and efficient water heater and working method thereof

Abstract

The invention relates to a double-heating and one-evaporation gas-liquid tank type multifunctional energy-saving and efficient water heater and a working method thereof. The double-heating and one-evaporation gas-liquid tank type multifunctional energy-saving and efficient water heater is characterized in that the water heater comprises a compressor, a first condensation heating pipe, a four-way valve, an air conditioning condensation pipe, a second condensation heating pipe, a throttling valve, an evaporator and a gas-liquid tank which are connected in sequence, the first condensation heatingpipe is arranged in a domestic hot water tank, the first end of the four-way valve is connected with the output end of the first condensation heating pipe, the second end of the four-way valve is connected with the input end of the air conditioning condensation pipe, and the third end of the four-way valve is connected with the first end of the evaporator. The double-heating and one-evaporation gas-liquid tank type multifunctional energy-saving and efficient water heater is simple in structure and reasonable in design, and can be used for improving the heat efficiency easily.

Description

Technical field: [0001] The invention relates to a dual-heat-steam liquid tank type multifunctional energy-saving high-efficiency water heater and its working method. Background technique: [0002] The current heating and cooling air conditioners or air-conditioning and hot water all-in-one machines and air-source water heaters all have the problem of low thermal efficiency in cold weather or hot summer. This is because the return air temperature absorbed by the compressor is too high in cold weather. low, resulting in low compressor efficiency; and in hot summer, the return air temperature absorbed by the compressor is too high, causing the compressor to work unstable, and sometimes shut down due to the high return temperature, which also reduces the working efficiency. Low. Invention content: [0003] The object of the present invention is to provide a dual-heat-steam liquid tank multi-functional energy-saving high-efficiency water heater and its working method. The...

[0002] The current heating and cooling air conditioners or air-conditioning and hot water all-in-one machines and air-source water heaters all have the problem of low thermal efficiency in cold weather or hot summer. This is because the return air temperature absorbed by the compressor is too high in cold weather. Low, resulting in low compressor efficiency; and in hot summer, the return air temperature absorbed by the compressor is too high, resulting in unstable compressor operation, and sometimes shut down due to high return temperature, which also reduces the working efficiency.
