Abstract

The invention relates to an easy-defrosting multifunctional heat pump water heater and solves a problem that a single air source and water source heat pump has to have both cooling and heating applications and meet different heat needs of all the year around and a frosting problem. The water heater comprises a refrigeration compressor, a fin-type air-cooled heat exchanger with a fan, and double-pipe heat exchangers A and B. An inlet side of the refrigeration compressor is serially connected with a gas-liquid separator. An outlet side of the refrigeration compressor is serially connected with a four-way valve A, a four-way valve B and the fin-type air-cooled heat exchanger with the fan and then forms a circulation loop through a one-way valve, a liquid vessel, a filter drier, level glasses, a three-way pipe and a four-way pipe. The device realizes four separated circulation systems, and can well realize full cooling and heating and supply heat meeting needs through different heat sources. The device has four functions of cooling, heating, making domestic hot water, and cooling and making domestic hot water. A process designed for the device can reasonably and reliably remove frost during operation in winter.

Description

technical field [0001] The invention relates to a water heater, specifically a multifunctional heat pump water heater. Background technique [0002] Heat pumps have obvious energy-saving benefits in providing domestic hot water and heating. A heat pump is a reversely utilized refrigerator, which only utilizes the heat of the condenser in the refrigeration cycle, and the refrigerator only utilizes the cold generated by the evaporator. If the heat discharged by the heat pump in the condenser and the cooling capacity generated by the evaporator can be used at the same time, the heat pump can obtain about double the energy efficiency ratio. However, the demand for cooling capacity and the demand for heat do not match in different seasons throughout the year. In summer, the demand for cooling capacity is large and the demand for heat is low. The situation is reversed in spring and autumn, while only heat is needed in winter. difference. At present, heat pumps with a single win...
