DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-type air-conditioning and heating system that is mainly small-sized for general households and is configured by connecting a plurality of indoor units to a single unit. Conventionally, heat bong type devices and hot water circulation type devices are known as cooling devices, but the former heat pump type uses outside air as the heat source (heat absorption) during heating. The lower the temperature, the lower the total force Ij[l, especially at night, within Km.
(a) As the number of units in operation increases, the efficiency decreases, which has the disadvantage of not being able to provide sufficient and comfortable heating. There is actually no problem of insufficient total power, but each guiding machine requires a hot water coil in addition to the cooling coil, which increases the size of the guiding machine and reduces the available space in the house. The heating heat source equipment and hot water piping for generation and supply are required separately from the cooling equipment and refrigerant piping, which has the disadvantage that the overall cost is extremely high in terms of both equipment costs and construction costs. In view of this excitement, a general purpose cold midfielder! lol
By making effective use of simple structural improvements, the heating action of a double A storm can be performed comfortably despite the increase in the t1 load, and the 4 t! There is a purpose in offering.

The multi-type air conditioning system m according to the present invention includes a compressor, a compressor J1
I[
This is an i multi-type air conditioning system configured by connecting several indoor units ttL rows, and the compression 1!
It is possible to interpose a refrigerant heater in the converging refrigerant flow path leading to the tc, and to make the high temperature refrigerant gas compressed by the pressure machine bypass the condenser and expansion valve and flow into the 1ff control unit. It is characterized by the provision of a bypass passage and a flow passage switching valve t. In other words, the compressor, condenser, expansion valve, guide machine, and compressor are connected in the order of refrigerant t** by a normal refrigeration cycle. By adding the refrigerant heater, bypass path, and flow path switching valve to a general-purpose multi-unit cooling device that can individually cool any number of rooms through a single guide machine, In response to an increase in heating load due to an increase in the number of indoor units in operation during a drop in outside air temperature, by controlling the amount of heat for the refrigerant by the refrigerant heater, a sufficient and comfortable heating effect can always be achieved without causing a lack of capacity. In addition to the effect on heating performance, the compressor used during cooling operation can be used as the main refrigerant gas blower during heating operation, and -st@ Since they can be used as flow paths for high-temperature and cold gas during room operation, there is no need for a dedicated heat source for heating and hot water piping, which were required in the conventional combined hot water circulation method mentioned above. There is no need to incorporate a hot water coil separate from the cooling coil into the machine, and the overall system can be configured cost-effectively, and the guide machine can be made as compact as possible, resulting in structural advantages.
