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. Background technique [0002] With the development of industry in today's society and the improvement of people's living standards, the requirements for traditional air-conditioning technology in industrial production and living life have also increased. On the basis of maintaining the comfort requirements of air-conditioning devices, they are required to be more energy-efficient. Less impact on the environment. [0003] "Heat pump" technology is recognized as a relatively energy-saving and environmentally friendly HVAC technology. The heat pump consumes the input mechanical wor...
