Embodiment Construction
[0049] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0050] In a specific embodiment, the exhaust air heat recovery antifreeze control method provided by the present invention is used to adjust the electric heating capacity of outdoor fresh air at any time according to the freezing point temperature and air conditioner operating parameters when the outdoor environment is low. In order to make the heat recovery efficiency of the fresh air exhaust as...

The embodiment of the invention discloses an exhaust heat recovery anti-freezing control method, device and system. The method comprises the steps that the heat recovery efficiency under the current temperature and humidity and rotating speed conditions is acquired, the exhaust temperature and exhaust humidity of indoor exhaust after heat recovery are calculated, it is judged that the exhaust temperature and exhaust humidity of indoor exhaust after heat recovery reach the freezing point, and the current freezing point is acquired as the temperature and humidity after heat recovery under the current condition; and the temperature value before fresh air heat recovery is used as the heating target temperature value, so that an electric heating device is controlled to heat outdoor fresh air tothe temperature before fresh air heat recovery, the heating quantity of the electric heating device is corrected, and the corrected heating quantity is adopted as the target heating quantity of electric heating. The technical problems that in the prior art, the electric heating quantity of exhaust heat recovery cannot be precisely controlled, and consequently a heat recovery core is frozen, or the heat recovery efficiency cannot be kept are solved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of air conditioners, and in particular to a method, device and system for exhaust air heat recovery antifreeze control. Background technique [0002] In an air conditioner with a fresh air conditioning system, in order to save energy, the heat recovery process will be performed on the exhaust air of the fresh air; High, and high moisture content, it is easy to cause the heat recovery core to freeze, affecting the heat recovery efficiency; if the electric heating is controlled on and off according to the outdoor temperature, it is not conducive to controlling the heating power, and the heat recovery efficiency cannot be maintained at a high level. Level. Contents of the invention [0003] For this reason, the embodiment of the present invention provides an exhaust air heat recovery anti-freezing control method, device and system to solve the problem that in the prior art, the electric...
