Abstract

The present invention relates to a heat recovery system for a multi-functional heat pump and a multi-functional air conditioner, which performs a variety of operation modes such as a cooling mode, a cooling and water heating mode, a heating mode, a heating and water heating, and a water heating mode and a defrost function applied in a cold weather. A simple arrangement of the refrigerant circuit to form the operation is provided.

Description

technical field [0001] The present invention generally relates to a multifunctional heat pump and a multifunctional air conditioner capable of operating in various operation modes including a defrosting function. Background technique [0002] The main difference between an air conditioner and a heat pump is that a heat pump can provide both cooling and heating whereas an air conditioner can provide cooling but not heating. Simple workshop modifications can convert an air conditioner into a heat pump, or vice versa. [0003] Multifunctional heat pumps and multifunctional air conditioners are generally configured with components such as compressors, heat exchangers, and valves such as solenoid valves, check valves, four-way valves, and expansion valves. The components are interconnected via pipes forming a refrigerant circuit. Refrigerant circuits can employ varying numbers of components and routes. [0004] In low ambient temperatures or cold climates, outdoor heat exchang...
