Decentralized air conditioning system with heat recovery

Abstract

One of the new developments of the company “Clivet" - a system with a "water loop" which can become an alternative to systems with controlled flow rate of refrigerant and carrying of heat and cold between rooms, lit system with a "water loop" is a decentralized system of air conditioning with the utilization of heat which allows to simultaneously heat and cool different rooms in multi-zone or multifunctional buildings.

The system consists of three main components:

• monoblock air conditioners with a heat pump and water condenser;
• water contour (loop) with its pump assembly and accumulation tank;
• sources of refrigeration (cooling tower) and heat (boiler) Since the optimum temperature of water in the contour is 18...35C, refrigeration can be accomplished in heat exchangers (dry cooling towers) that are taken out.

To fulfill these goals "Clivet" company is producing all the necessary equipment: terminal blocks of different types and capacity - console, channel, cabinet, roof. The monoblock air conditioner is a refrigeration unit including all the elements of refrigeration cycle: compressor, water condenser and evaporator. Pie air conditioner can be installed either directly in a room, like a fan-coil unit, or outdoors, it has a built-in control and provides refrigeration or heating in a particular room. As distinct from most of the individual heat pump systems, the system with a "water loop” can be most advantageously used in the countries with cold climate, for example of Northern Europe, and in Russia. And the economical efficiency of the system with "water loop" is considerably higher, than that of freon multi-zone systems.
