Description

one

The invention relates to the field of air treatment, in particular, to air conditioning using an absorption refrigeration unit as a cold supply source.

A known air conditioning system comprising an irrigation-type air cooler included in the coolant circuit and an absorber chiller evaporator and a surface air heater, an absorber and a condenser of the same machine 1 included in the water circulation circuit.

However, this system becomes uneconomical during the winter period. It is EARLY because the need for a source of cold supply is eliminated and the absorption refrigeration unit is not used.

The goal of the invention is to increase the energy through year-round use of the chiller.

This is achieved by the fact that in the proposed system the evaporator is additionally connected to an external water source, for example, to the water supply network, and is disconnected at the connection points to this source and to the refrigerant circuit, they are turned off by valves, and the generator of the refrigerating machine is connected to the heating system. .

The drawing shows the scheme of the proposed system.

The air conditioning system contains an irrigation chamber 1, an evaporator 2 of an absorption refrigeration unit, a surface air heater 3, an absorber 4, a condensate 5, a water supply network 6, disconnecting, a valve 7, a generator generator 8 of the refrigerating machine, and a heating system 9.

The operation of the air conditioning system is as follows.

The treated air passes sequentially through the irrigation chamber 1 and the surface air heater. The heat source for the latter is the absorption chiller that is not disconnected in winter, while its absorber 4 and condenser 5 are connected to the surface air preheater 3, which utilizes their heat, and the evaporator tubes 2 are disconnected from the irrigation chamber and connected to the water supply network 6. The irrigation chamber is in operation at this time on tap water.

To ensure the operation of the generator of the absorption chiller during the winter period, its tubes are connected to the return pipe of the heating system 9. The connection of the surface air heater to the absorber tubes and the condenser of the absorption chiller provides heat utilization of the latter and allows the special boilers to be rejected, the connection of the absorption cooler evaporator tubes machines with a water supply network allows the machine to operate as a heat source for an air heater with no Zmennom mode of treatment of air passing through the irrigation chamber.

Connecting an absorption chiller generator to the heating system's return pipe allows you to save on the use of the waste heat and ensures that the absorption chiller works during the winter period, i.e. year-round. This increases the efficiency of the air conditioning system by increasing the utilization rate of the chiller. Year-round use of the machine increases the reliability of the system as a whole and simplifies its operation.
