what is a unitary air conditioning system

The liquid refrigerant passes through the evaporator coils.

The remaining part of the used air is again conditioned and this will repeat again and again.Air conditioner working principle in summer air conditioning system. If sufficient data of the required is not available, then it is assumed to be 21°C dry bulb temperature and 50% relative humidity.Ex. Air conditioning can be used anywhere you go or stay. Now the conditioned air is supplied to the conditioned space by a fan. As the name implies, there are window-installed. Window air conditioners cool a particular room by drawing out hot air and sending in cool air in return. If the whole building is to be air conditioned, HVAC engineers find that putting individual units in each of the rooms is very expensive making this a better option. The sensing bulb or electronic sensor is clipped to the front of the evaporator coils to monitor the temperature of the air entering the coils.Once the room has sufficiently cooled the thermostat control shuts off the voltage to the compressor. In this article, we will discuss Pattern and Its Functions, Materials, Types of pattern & Types of Pattern Allowance.

The present invention relates to an air conditioning system, and particularly, to a unitary air conditioning system provided with an outdoor unit and a plurality of blower units connected to the outdoor unit, for cooling or heating each zone inside a building.In general, a unitary air conditioning system is a kind of central heating and cooling system in which cool air or warm air is made by using a heating and cooling device provided in a factory, an office, a hotel, a house or the like, and supplied to each zone through a pipe or a duct provided in a building.In the unitary air conditioning system, to independently supply the cool or warm air to individual zones by distinguishing a zone requiring cooling or heating and a zone which does not so, a zone controller for distributing the cool or warm air is installed on a duct, or a plurality of heating and cooling devices are individually installed correspondingly to a plurality of zones.The outdoor unit 1 includes a compressor 1a for compressing refrigerant; a first heat exchanger 1b connected to the compressor 1 a by refrigerant pipes, for heat exchange between refrigerant and ambient air; an expander 1 c for expanding volume of refrigerant and reducing pressure of refrigerant; a four way valve 1d disposed adjacent to the compressor 1a, for circulating a compressed refrigerant discharged from the compressor 1a according to a heating cycle or a cooling cycle; and an accumulator 1e disposed in the vicinity of a refrigerant inlet of the compressor 1a, for filtering a liquefied refrigerant.The central blower unit 2 includes a second heat exchanger 2a connected to the compressor 1 a and the expander 1 c by refrigerant pipes, respectively; and a supply fan (not shown) disposed adjacent to the second heat exchanger 2a, for supplying the cool or warm air to the supply duct 3.A plurality of discharge openings 3a are formed at the supply duct 3 to supply the cool or warm air to a zone requiring cooling or heating, and a plurality of suction openings 4a through which the air of each zone is sucked are formed at the return duct 4.The zone controller 5 is composed of valve 5a, 5b, 5c and 5d for selectively supplying the cool or warm air to each zone (Z1) and (Z2), wherein the valves are installed at the supply duct 3 and the return duct 4 arranged in the corresponding zone (Z1) and (Z2).

The mixed air passes through a filter to remove the dirt, dust and impurities.The air now passes through a cooling coil. Located the back of the unit.

However, it may cause an increase in cost, which is very inefficient.Therefore, an aim of the present invention is to provide a unitary air conditioning system capable of effectively performing cooling or heating operation corresponding to a load of each zone by being provided with a cooling/heating control unit for selectively distributing a refrigerant from an outdoor unit to each blower unit for performing cooling or heating operation on each zone.Another aim of the present invention is to provide a unitary air conditioning system capable of individually cooling or heating a specific zone having high loads or having no duct by employing an individual cooling and heating system within a central cooling and heating system performing heating and cooling operation on each zone in a building.To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a unitary air conditioning system according to claim 1.

Decentralized air conditioning systems commonly known as by various generic names viz. In this system, the air is cooled and generally dehumidified. This minimizes the interior system footprint and allows each room to be adjacent independently.PTAC system may be adapted to provide heating in cold weather, either directly by using an electric strip, gas or other heaters, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air into a heat pump.While room air conditioning provides maximum flexibility when cooling rooms it is generally more expensive than a central air conditioning system.So now, we hope that we have clear all your doubts about the Air conditioning system.

PTAC systems are also known as wall split air conditioning systems or ductless systems.These PTAC systems which are widely used in hotels have two separate units, the evaporative unit on the interior and the condensing unit on the exterior, with tubing passes through the wall and connect them together.
