Abstract

The invention discloses a centralized multi-connected cold (heat) source central air conditioning system which comprises a central air conditioning device, a cold / heat source system and a circulation pipeline system, wherein the central air conditioning device comprises water-cooling heat pump type central air conditioners in a plurality of regions, the cold / heat source system comprises a plurality of heat exchange systems which are connected in parallel, the connection pipe of each heat exchange system is provided with a corresponding temperature-difference electrically operated valve, and the opening of the valve is controlled by the temperature of heat exchange media and cold / heat sources. By decomposing a bigger simplex central air conditioning device into the smaller regional central air conditioners, the invention thoroughly eliminates energy consumption caused by pipeline insulation, improves the safety and the heat exchange efficiency of the central air conditioning, lowers the operating cost of the central air conditioning system by using the multiple cold / heat sources, and utilizes energy in natural environment and wastes to the greatest extent, thereby achieving the purpose of energy saving and consumption reduction.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a centralized multi-connected cold (heat) source central air-conditioning system with less transmission loss and fully utilizing natural environment energy. Background technique [0002] In the air conditioning system, a common household air conditioner includes a compressor, an evaporator installed indoors, and a condenser installed outdoors. Under the action of the compressor, the refrigerant transfers the cold or heat in the room to the The outdoor condenser then diffuses into the atmosphere or absorbs heat from the atmosphere to complete the air conditioning process. Due to the installation of the outdoor unit, it is easy to damage the appearance of the exterior wall of the building, and the fins of the condenser are easy to accumulate dust, resulting in a decrease in heat exchange efficiency. , so it is not suitable for larger air-conditioning systems. Generally, larger central ...
