Problems solved by technology

The main disadvantages of these methods are: 1. Frosting cannot be avoided, so that the system performance reduction caused by frosting cannot be avoided; 2. The heat released during the defrosting process cannot be recycled, which increases the energy consumption of the system

Abstract

The invention provides a solid adsorption technology based frostless air source heat pump system. The solid adsorption technology based frostless air source heat pump system comprises an air channel, a compressor, a condenser, a drying heat exchanger, an evaporator and a fan. The air channel is in a shape of a Chinese character 'ao', two shoulder portions of the air channel are respectively provided with an air outlet and an air inlet, and two mutually parallel side walls, perpendicular to the air inlet direction, on the air channel are respectively the first air channel side wall and the second air channel side wall. The drying heat exchanger, the evaporator, the fan, a first air valve, a second air valve, a third air valve and a fixing device are arranged in the air channel. The solid adsorption technology based frostless air source heat pump system can avoid evaporator frosting, and the operating energy efficiency of the system is improved. Under the moisture absorption effect of a drying agent, the moisture content of air undergoing heat exchange of the evaporator is reduced, the dew point temperature of the evaporator is reduced and is made lower than evaporation temperature, and the frostless operating effect of the evaporator is achieved.

Description

technical field [0001] The invention relates to a frost-free air source heat pump system, in particular to a frost-free air source heat pump system based on solid adsorption technology. Background technique [0002] An air source heat pump is an electrically driven device that uses a refrigeration cycle to absorb heat from the air for heating water or air. Compared with ordinary electric heating, it can save 50% to 70% of electricity consumption. The advantages of energy saving and environmental protection of air source heat pumps have made them more and more widely used in heating, hot water and other fields. [0003] The working principle of the air source heat pump is that the refrigerant is compressed by the compressor into a high-temperature and high-pressure gas, which passes through the condenser and becomes a high-pressure liquid. In the condenser, the condensation heat is released to the hot water or air to be heated, and becomes The low-pressure gas-liquid two-pha...
