Abstract

The invention provides a broad-width type air source heat pump device. A working principle of refrigerating in summer is as follows: a low-temperature refrigeration compressor set does not work, and a high-temperature refrigeration system composed of a middle-temperature and high-temperature refrigeration compressor controls a relative switch to be automatically switched to a refrigeration mode to be operated through an electric control system which is set by the device. A working principle of heating in winter is as follows: when the environment temperature is higher and the humidity is smaller, the low-temperature refrigeration compressor set does not work, and the high-temperature refrigeration system composed of the middle-temperature and high-temperature refrigeration compressor controls the relative switch to be automatically switched to a winter heating mode to be operated through the electric control system which is set by the device; when the environment temperature is lower or the humidity is larger, the middle-temperature and high-temperature refrigeration compressor does not work, and a low-temperature refrigeration system composed of a low-temperature refrigeration compressor controls the relative switch to be automatically switched to be put into work through the electric control system which is set by the device, so that heat can be continuously collected from the environment atmosphere and the requirements of heating under cold and high-humidity conditions are met.

Description

Technical field

[0001] The invention relates to refrigeration and heating technology using ambient air source as a cold and heat medium, in particular to a wide-width air source heat pump device, which can provide sufficient cooling capacity for air-conditioned places in summer and can be under low temperature and high humidity conditions in winter , Collect heat from the ambient atmosphere to meet the heating needs of people in cold and high humidity areas. technical background

[0002] Air source heat pump units have been widely used in various air-conditioned places such as hotels, hotels, offices and residences due to their simple installation and far higher heating efficiency in winter than electric heating methods.

[0003] In fact, the ambient temperature in the Yangtze River Basin in China is around -10°C in winter. The compressor failure rate of traditional air source heat pump units in winter is very high. The fin heat exchangers defrost frequently, and the heating area t...
