Description

Fan coil unit for both central Cooling-heating and local heating}

The present invention relates to a fan coil unit for central heating and individual heating, and more particularly, by controlling the operation of a fan coil for central heating and PTC heater for individual heating, so that both central heating and individual heating can be used. will be.

In particular, the present invention is to switch to individual heating when the central heating is stopped in the winter evening (for example, after 6 pm), PTC (Positive Temperature Coefficient) heater and heat pipe during the individual heating The present invention relates to a central heating and cooling fan coil unit that can improve thermal efficiency and minimize power consumption.

In general, the method of heating the indoor space is the central heating and individual heating.

Central heating is mainly operated in multi-unit buildings such as high-rise buildings or apartments because of its high thermal efficiency and convenient management.

The central heating adjusts the supply temperature and the supply time of the heating water according to the temperature outside of the season to be supplied to each room or each household uniformly.

Even in the case of a fan coil unit capable of cooling and heating in one configuration, there is a difference in supplying cooling water or heating water depending on the season, and the basic operation is similar to that of central heating.

However, since central heating provides the same heating temperature for each household and each room, many residents feel uncomfortable because they do not reflect the haptic temperature differently.

For this reason, in recent years, the application of individual heating in multi-unit buildings such as high-rise buildings and apartments is increasing.

In the case of individual heating, each household or each room is equipped with a separate heating device, and it is operated by heating it individually, and each residents can provide the desired room temperature, but in terms of total energy consumption, In comparison, much energy can only be used.

Recently, Korean Utility Model No. 20-0287607 uses a heating device using electronic devices, such as "Heating fan composed of carbon heater" and Korean Utility Model No. 20-0411130, "PitiC ceramic heater for heating device." Efforts are being made to reduce the amount of energy.

However, most of heating devices using electronic devices are assumed to be used only for a short time. When heating them for a long time using these devices in a place where central heating is not performed, the total energy consumption is lower than that of central heating. Not only is it significantly increased, but the performance of the electronic device deteriorates drastically if the use time lasts for a long time, the power consumption may increase rapidly.
