Description

Multi zone air-conditioning unit
Technical description
The multi zone air-conditioning unit is designed for multi zone hot air and hot water heating systems, ventilation, heating and cooling recuperation, heating water for family houses and residential buildings.
Current status of the technology
The currently used four-socket air-conditioning units with integrated heat pump for waste air recuperation for heating of the inlet air enable a single basic mode of isobaric ventilation with air heating or potentially cooling by means of a reverse interchangeable operation of the condenser and evaporator. These units cannot ensure efficient hot air heating and cooling in a circulation mode with a controlled inlet of ventilation air, for example, by a CO2 sensor in modern passive buildings, and are not even adapted or dimensioned for an external energy source of water heating systems or heating of utility water. The units usually feature the so-called "active heat recuperation", without installed "air-to-air" recuperation exchangers, only with condenser and evaporator registers and the necessary and frequently uneconomical permanent run of the coolant circuit.
There are also five-socket units with supply of external air to the built-in register via a separate socket. These, however, do not feature multi zone modes with independent ventilation and circulation heating of residential areas, sanitary facilities and areas with higher load of noxious substances.
Basis of the technical solution
The mentioned deficiencies are removed by a multi zone air-conditioning unit where the intake sector of the supplied fresh is connected via a cross-counterflow heat exchanger to a sector mixing the intake of the inner circulation air, which continues to the fan sector with a coolant register of the inner circulation circuit for ventilation, heating and cooling where the intake sector of the inner waste air is connected via a cross-counterflow heat exchanger to a sector mixing the external outdoor air intake and continues to a fan sector with a coolant register of the outdoor external air exhaust. The mixing sectors of the inner circulation intake and the external outdoor air intake incorporate a joint rotary shut-off and control flap or potentially a separate slatted shut-off flap and control flap, which are mutually interlocked. The fan sector of the coolant register also incorporates a register of a bivalent/backup external heat source.
The basic advantage of the proposed design is integration of an "air-air" source reverse heat pump with a multi zone unit, which creates a multi zone functional scheme with a wide range of optional operating modes. The resulting concept of the unit with six sockets thus also ensures (in contrast with the current concepts) hot-air heating/cooling circulation in residential areas separately from the underpressure ventilation of the sanitary facilities. It further allows operation in an "active recuperation" mode, i.e., ventilation of another zone of separate areas with a higher load of noxious substances. In all of these operating modes, the mentioned functional schemes can be mutually combined.
In all operating modes, the multi zone air-conditioning unit also allows feeding of heating and utility water into an external integrated accumulation reservoir with a built-in spiral for heating water and a flow-heater spiral for potable water via a built-in "coolant-brine" panel exchanger.
Overview of figures in the drawing
In the attached drawings, Figure 1 shows a front diagram of the multi zone air-conditioning unit in vertical design with integrated rotary shut-off and control flaps. Figure 2 shows the same chart, but with slatted shut-off and control flaps. Figure 3 shows a diagram of airflow in this unit in the heating/cooling circulation mode in residential rooms without ventilation and with rotary flaps. Figure 4 shows the same airflow chart, but with slatted flaps. Figure
5 shows a diagram of airflow in this unit in isobaric ventilation mode in the 1st zone of the building (toilet, bathrooms, kitchens) with potential supplementary heating/cooling. Figure
6 shows the same airflow chart, but with slatted flaps. Figure 7 shows a chart of airflow in this unit in a combined mode of heating/cooling circulation with independent ventilation of the 1 st zone of the building with rotary flaps. Figure 8 shows the same airflow chart, but with slatted flaps. Figure 9 shows a chart of airflow in this unit in the "active recuperation" mode with separated ventilation and another 2nd zone of the building with rotary flaps. Figure 10 shows the same chart, but with slatted flaps.
Examples of implementation
According to Figure 1, the multi zone air-conditioning unit consists of housing 1 with a compressor 2 separately located in its bottom part together with a panel exchanger 3 and accessories of the coolant circuit 4; the top section of the housing 1 incorporates a cross- counterflow heat exchanger 5 with a subsequent sector 6 of the supplied outdoor fresh air and inlet socket 7 of the supplied outdoor fresh air with filter 8. The recuperation exchanger 5 is connected to the mixing sector 9 of the inner circulation air with a rotary shut-off and control flap 10, filter 11 and inlet socket 12 of the inner circulation air. The sector 9 is connected to the fan sector 13 with a coolant register 14 of the inner ventilation circulation circuit, a supply fan and outlet socket 16. The cross-counterflow heat exchanger 5 is further connected to the intake sector 17 of the inner waste air with inlet socket 18, filter 19 and a mixing sector 20 for suction of the external outdoor air with rotary shut-off and control flap 21 and inlet socket 22 of the outdoor external air. The mixing sector 20 is connected to the fan sector 23 with a coolant register 24 of the outdoor external air exhaust and an exhaust fan 25 and outlet socket 26. The fan sector 13 incorporates another register 27 of the bivalent backup heat source.
In an option according to Figure 2, slatted shut-off and control flaps 28 and 29 are located in the mixing sectors 9 and 20.
