Abstract

The invention discloses a novel frostless air source heat pump water heater which comprises a refrigerating fluid circulation loop, an air compressor and an air expander. The refrigerating fluid circulation loop comprises a compressor, a condenser, a throttling device and a heat exchanger which are connected through refrigerating fluid pipelines. The heat exchanger comprises a shell, a coil placed inside the shell, an air inlet and an air outlet. Refrigerating fluid circulates in the coil, and an air leading-in space is formed inside the shell outside the coil. The air inlet is connected with the air compressor, the air outlet is connected with the air expander, so that the air output through the air compressor is input to the air leading-in space from the air inlet to conduct heat exchange with the refrigerating fluid, and then the air is output to the air expander from the air outlet after heat release. The novel frostless air source heat pump water heater is simple in structure and capable of effectively preventing frosting.

Description

technical field [0001] The invention relates to a water heater, in particular to a novel frost-free air source heat pump water heater. Background technique [0002] The air source heat pump water heater is a "heat transfer" device that uses the principle of refrigeration to absorb heat from the air to produce hot water. The heat in the environment is transferred to the water by allowing the working fluid to continuously complete the thermodynamic cycle process of evaporation (absorbing heat from the environment) → compression → condensation (release heat) → throttling → re-evaporation. The device mainly obtains heat energy from the air, has the advantages of energy saving, environmental protection, and safety of the solar water heater, and solves the problem that the solar water heater relies on sunlight for heating and installation is inconvenient. In addition, it has no danger of electric water heater leakage. [0003] However, the currently used air source heat pump wat...
