Integral air source and ground source composite heat pump device

Abstract

The invention discloses an integral air source and ground source composite heat pump device. During mixed use of a heat pump, air and soil serve as cold and heat sources for refrigerating / heating. The heat pump mainly comprises a compressor, a four-way valve, an outdoor heat exchanger, a fan, a circulating water pump, a ground source heat exchanger, a throttling mechanism, a one-way valve, a reservoir and an indoor heat exchanger, wherein the outdoor heat exchanger consists of a refrigerant pipe, a water pipe and fins; and the water pipe is arranged on the inner side of the refrigerant pipe, so that circulating water exchanges heat with refrigerants, and the refrigerant pipe comprising the water pipe passes through the fins to realize heat exchange between the refrigerants and the air. The device is a heat pump system, low-energy-consumption environment-friendly shallow soil is used as a cold and heat source, a feasible scheme is provided for solving the problem of hot soil stack caused by long-term use of a ground source heat pump, and the heat pump device has a simple structure, low cost, reliable performance and a high energy efficiency ratio.

Description

technical field [0001] The invention belongs to the field of refrigeration machinery, and relates to a novel integrated air source and ground source composite heat pump device technology, in particular to a combination of air source and ground source as a composite cold and heat source, and a vapor compression refrigeration cycle , a heat pump device that meets the needs of indoor air conditioning.

This invention adds an evaporator, which makes the equipment pipeline more complicated, increases the burden of frequent switching valves of the system, and cannot use the two kinds of evaporators at the same time

[0009] Patent No. ZL 200720062510.7 is an invention patent. This invention provides a water source / air source hybrid evaporator and condenser. The flow of source water dissipates heat or takes heat from the fins to defrost the fins and cool the fins. The design of the auxiliary pipe in this invention cannot improve the efficiency of the refrigeration or heating cycle. On the contrary, the auxiliary pipe will Block the flow of air, affect the heat transfer capacity of the refrigerant pipe, and reduce the performance coefficient of cooling and heating
