Fresh air purifying system for air source heat pump

Abstract

The invention discloses a fresh air purifying system for an air source heat pump. The fresh air purifying system is characterized in that the air source heat pump serves as a cold / heat source for heating / refrigerating fresh air. Working medium coils of two outdoor fluorine / gas heat exchangers forming the air source heat pump are designed to be two parts of working medium coils which are connected in parallel, one part of the working medium coils are provided with electromagnetic valves. By means of the fresh air purifying system for the air source heat pump, working media can selectively flow through part of or all the working medium coils according to different seasons; and filtering nets are further designed, outdoor fresh air passes through an air channel, the initial-efficiency filtering net, the intermediate-efficiency filtering net, the outdoor fluorine / gas heat exchangers, the high-efficiency filtering net, an air supply machine and an air supply channel and enters a room from an air supply port.

Description

technical field [0001] The invention relates to a fresh air purification system, in particular to a fresh air purification system which utilizes an air source heat pump to heat and / or cool fresh air. The invention belongs to the technical field of air conditioning and air source heat pump. Background technique [0002] The winter smog is severe in the cold regions of northern my country. For the sake of health, more and more families and units have installed air purifiers. In closed buildings, especially in densely populated areas, a fresh air ventilation system has also been installed. [0003] The existing indoor air purifiers on the market cannot introduce fresh air, and are prone to produce ozone harmful substances and carbon dioxide concentrations exceeding the standard. Staying indoors for a long time is easy to dizziness! However, the existing fresh air ventilation system in the market has the function of purifying air and supplying oxygen, but due to its large volu...

[0003] The existing indoor air purifiers on the market cannot introduce fresh air, and are prone to produce ozone harmful substances and carbon dioxide concentrations exceeding the standard. Staying indoors for a long time is easy to dizziness! However, the existing fresh air ventilation system in the market has the function of purifying air and supplying oxygen, but due to its large volume and weight, it is installed under the indoor ceiling, and the installation process is noisy, which is unbearable for users and causes a large damage to the building ceiling. Bearing capacity; the bigger disadvantage is that due to the low temperature of the outdoor fresh air in the cold northern region, even though it is sent into the room through the heat recovery heat exchanger, the temperature of the fresh air is still very low, causing discomfort to the human body
