Description

Convective radiation air conditioning terminal and air conditioning system

technical field

The utility model relates to the technical field of air conditioners, in particular to a convection radiation air conditioner terminal and an air conditioner system.

Background technique

Central heating is not used in hot summer and cold winter areas in my country, and there are various types of heating ends in winter, which can be mainly divided into convection ends and radiation ends. The convection end (such as fan coil unit, household air conditioner, etc.) realizes heating by delivering hot air to the room, which has the characteristics of high intermittent but poor comfort. In the existing radiant heating terminal, the hot water heating radiant terminal (such as floor heating, radiator, etc.) is mainly produced by a compressor/gas wall-hung boiler, thereby heating the room. Although this heating system is highly comfortable, due to the large thermal inertia and the small heat transfer coefficient between the terminal and the room, it takes a long time from startup to stable heating state and has the defects of poor intermittent performance, so most of the radiation The heating terminals operate continuously, and the energy consumption of radiant heating terminals is higher than that of intermittent heating household air conditioners. According to the climatic characteristics of hot summer and cold winter regions in my country, intermittent heating should be used for heating in winter in this region. Therefore, improving the intermittency of the existing radiant heating terminal is the key to improving the applicability of the radiant terminal.

In the current market, there is a technology of radiant heating using heat pipes/plate heat pipes. Although this method can achieve the function of rapid heating at the end, it does not effectively solve the problem of difficult "end-indoor" heat exchange, which will make heating indoors difficult. is still slower, with an intermittent similar to existing radiant heating ends such as radiators.

The problem of not being able to use both. In addition, the existing cold and heat sources at the radiant end all come from the water system, so there is a heat exchange link from the heat source to the water system, which will cause a certain heat loss.

In view of this, there is an urgent need for a convective radiation air conditioning terminal and an air conditioning system, which can solve the above problems.
