Abstract

The invention discloses a balcony hanging solar-air source composite heat pump system, which is provided with an air source heat pump module and a hanging solar water heater/heat exchanger module which are connected with each other; wherein, the air source heat pump module is a normal heat pump; an outdoor heat exchanger is connected in parallel with the hanging solar water heater/heat exchanger which mainly consists of a large aperture pressure-bearing vacuum glass heat collecting pipe, a pressure-bearing stainless steel sleeve, a cold water splitting device and a U-shaped refrigeration copper pipe. The hanging solar water heater/heat exchanger can have the effect of the solar water heater and can utilize the solar energy and the condensation heat of the heat pump under different working conditions, thus having the function of the heat exchanger. The system has no heat accumulation water tanks, is simple and easy to assort with a traditional air source heat pump, and is especially applicable to the vertical surface of the southern wall or the lower surface of the southern balcony of a high-rise tower building; the solar heat collector and the air source heat pump can be combined to run, thus achieving the object that the advantages in summer, winter and transitional seasons can be mutually supplemented; and furthermore, the heat supply and coldness supply performance coefficients during the annual running period of the air source heat pump are improved and the stability and reliability problems of the hot water supply of the solar water heater are solved.

Description

technical field [0001] The invention belongs to the technical fields of an environment-friendly compound heat pump, a novel heat pump operation mode and solar energy utilization. Background technique [0002] The development and application of building energy-saving technology has important practical significance for reducing building energy consumption and saving energy. In recent years, energy-saving technologies such as air source heat pump systems and solar water heating systems have made great progress. [0003] Air source heat pumps are widely used in various types of buildings such as modern office buildings, hotels, factories, and residences due to their simple structure, low operating costs, dual-use in winter and summer, high equipment utilization, and convenient installation and use. According to statistics, air source heat pumps account for more than 45% of building air conditioners in my country. [0004] In winter in northern my country, coal (gas) is still t...
