Problems solved by technology
However, when the full heat exchanger is used, the full heat exchanger will increase the pressure head between the fresh air and the exhaust air, resulting in a large increase in the fan energy consumption of the fresh air dehumidifier
In turn, the filter element of the total heat exchanger is easily damaged, or as the service time of the total heat exchanger increases, the heat exchange efficiency of the total heat exchanger decreases, which cannot meet the use requirements

The invention provides a fresh air dehumidifier. The fresh air dehumidifier comprises an exhaust heat recovery coil pipe, wherein an inlet of the exhaust heat recovery coil pipe is connected with an outer unit liquid pipe connector of an outdoor unit. The fresh air dehumidifier further comprises a backheating coil pipe, an outlet of the exhaust heat recovery coil pipe is connected with the backheating coil pipe through a first one-way valve, an outlet of the exhaust heat recovery coil pipe is connected with a first electromagnetic valve through the first one-way valve, and the first electromagnetic valve and the backheating coil pipe are connected in parallel. The fresh air dehumidifier further comprises a first coil pipe, one end of the first coil pipe is connected with the first electromagnetic valve, the heating coil pipe and a second one-way valve, and the first coil pipe is connected with the outer unit liquid pipe connector of the outdoor unit through the second one-way valve. According to the fresh air dehumidifier, the exhaust heat recovery coil pipe, the backheating coil pipe and the first coil are arranged, so that the circulation flow of a refrigerant can be realized, and the utilization efficiency of energy can be improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a fresh air dehumidifier. Background technique [0002] Current fresh air dehumidifiers usually require fresh air to be pretreated (heated or cooled) when fresh air is introduced into the room. When the fresh air is pretreated, heat or cooling is usually recovered from the indoor exhaust gas, so as to improve energy utilization efficiency. On existing fresh air dehumidifiers, total heat exchangers are usually used to recover heat or cold. However, when the total heat exchanger is used, the total heat exchanger will increase the pressure head between the fresh air and the exhaust air, resulting in a large increase in the fan energy consumption of the fresh air dehumidifier. In turn, the filter element of the total heat exchanger is easily damaged, or as the service time of the total heat exchanger increases, the heat exchange efficiency of the total heat exchang...
