Backflow type cold and warm air heating radiator

Abstract

The invention provides a backflow type cold and warm air heating radiator. The backflow type cold and warm air heating radiator comprises a shell, a heat exchanger, a fan and a control device, wherein an air inlet and an air outlet are formed in the shell, and the air outlet communicates with an airflow channel below an indoor floor; the heat exchanger is arranged in the shell, and air from the air inlet can be converted into hot air or cold air by the heat exchanger; the fan is arranged in the shell and is located at the air outlet, and the hot air or the cold air can be sent to the airflow channel by the fan; and the control device is respectively connected with the heat exchanger and the fan so as to control the heat exchanger and the fan to start and stop. According to the backflow type cold and warm air heating radiator of the scheme, the incoming air is heated or cooled by the heat exchanger, then the hot air or the cold air is sent to the airflow channel below the indoor floor through the air outlet in the bottom of the shell under the thrust of the fan, and the cold air or the hot air flows in the airflow channel under positive pressure, so that the cold air or the hot air is quickly and uniformly diffused; in addition, by adopting a working mode of underfloor air supply, the generated hot air or cold air can circulate indoors through the airflow channel so as to adjust indoor temperature.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a reverse flow cooling and heating fan. Background technique [0002] In the existing technology in the field of air conditioning, according to theoretical calculations, heating or cooling buildings by adjusting the indoor air temperature of the building is the best, fastest and most energy-saving method, so in many buildings Central air-conditioning units, household air-conditioning units, heat pump units, etc. are installed for heating or cooling. [0003] In this type of air conditioning system, a key issue in the heat exchange between the heat source unit and the building is how to reasonably select the air supply and return modes and the installation location of the heat exchange equipment to achieve the best air conditioning effect. [0004] In the prior art, the form used in the air conditioning system is usually to install the air supply and return cha...

Problems solved by technology

Although its air-conditioning effect is good, sometimes because the air supply and return modes are opposite to the airflow principle of "hot up and cool down", it is impossible to achieve the air-conditioning effect that matches the theoretical results, especially in winter In areas where heating is required, not only the ideal heating effect cannot be achieved, but energy is also seriously wasted sometimes, making it difficult to popularize and use the air conditioning mode with the best energy-saving potential in the heating field

[0005] In other words, in the prior art, there are defects such as the installation position of the heat exchange equipment and its air supply and return modes, which are contrary to the air flow principle; in the air conditioning process, the ideal effect cannot be achieved, and sometimes there is a serious waste of energy. or question
