Problems solved by technology

[0014] When the ambient air temperature drops to 5°C, frosting on the surface of the wind-side heat exchanger accelerates, and the heating capacity of the unit decreases intensified; when the ambient air temperature falls below -5°C to -10°C, the ordinary air-cooled heat pump unit It is difficult to operate normally, which affects the application of air-cooled heat pump units in cold regions (such as the north of the Yellow River Basin)

Abstract

A combined air-cooled heat pump set is characterized by that the water-source heat pump set is combined with the air cooled heat pump set via water circulating mechanism to form a whole. In the summer, both heat pump sets are respectively used for refrigeration. In the winter, the air cooled heat pump set is used to heat water to 21 deg.C and then the water-source heat pump set is used to further heat the water to 45 deg.C for heating indoor air.

Description

【Technical field】 [0001] The invention relates to an air-cooled heat pump unit with dual functions of cooling and heating. 【Background technique】 [0002] The air-cooled heat pump is a central air-conditioning unit with air as the cold (heat) source and water as the cooling (heat) medium. As an integrated device with both cold and heat sources, the air-cooled heat pump unit omits cooling towers, water pumps, boilers And the corresponding piping system and many other accessories, the system has a simple structure, occupies a small space, is convenient for maintenance and management, and saves energy, especially suitable for areas lacking water sources. Therefore, air-cooled heat pump units are usually the preferred solution for many HVAC engineering designs that have no heating boilers, heating networks or other stable and reliable heat sources, but require air conditioning throughout the year. [0003] The traditional air-cooled heat pump unit air conditioning system such a...
