Technical Field

The invention relates to an air conditioner, in particular to an air conditioner indoor and outdoor unit connecting pipe and an air conditioner system.

Background

In a conventional one-to-one refrigeration air-conditioning system (see fig. 1), because only one heat exchanger is arranged indoors and outdoors, the connecting pipes of the indoor machine and the outdoor machine only need two connecting pipes, namely a gas connecting pipe and a liquid connecting pipe, and the installation and the matching are simple and convenient. However, from the viewpoint of energy efficiency of the refrigeration system, the conventional one-in-one air conditioning system can cause the evaporation temperature of the system to be lower in order to meet certain dehumidification and cooling requirements. And under the condition of a certain condensation temperature of the system: the lower the evaporation temperature, i.e. the higher the compressor suction-to-discharge pressure ratio, the lower the energy efficiency of the system. In order to solve the problem of low system energy efficiency caused by the fact that the return air temperature and the evaporating temperature are too different when an air conditioning system operates, the invention with the publication number of CN105444453B provides a double-temperature refrigerating and heating system which is a double-evaporating temperature air conditioning system adopting a double-suction double-row or double-suction single-row compressor, namely two high-temperature evaporators and two low-temperature evaporators are respectively arranged in a single heat exchange channel or the same heat exchange channel, indoor return air is subjected to heat exchange through the high-temperature evaporators and the low-temperature evaporators successively, and outlets of the two evaporators are respectively connected with two independent compression cylinders of the compressor, so that the evaporating temperature of the high-temperature evaporators is higher than the evaporating temperature of a conventional system, the ratio of the suction pressure to the exhaust pressure of the high-temperature side is reduced, and the operating power of the system is reduced, and the.

However, in the above-mentioned warm cooling and heating system, because two heat exchangers are arranged indoors and the outdoor unit compressor has two forms of single exhaust and double exhaust, the problems of excessive connecting pipes between the indoor unit and the outdoor unit of the air conditioner, complex after-sales installation and the like are caused.

The second purpose of the invention is to provide an air conditioning system applying the connecting pipe for the indoor unit and the outdoor unit of the air conditioner.

The technical scheme for solving the technical problems is as follows:

the connecting pipe for the internal and external machines of the air conditioner comprises a pipe body and a plurality of groups of connecting joints arranged on the pipe body, wherein the plurality of groups of connecting joints are uniformly arranged at two ends of the pipe body; the pipe body is internally provided with a plurality of groups of mutually independent connecting pipelines, the number of the connecting pipelines is consistent with that of the connecting joints on one side in the pipe body, each connecting pipeline extends along the length direction of the pipe body, and two ends of each connecting pipeline are respectively communicated with the two corresponding connecting joints.

An air conditioning system comprises the air conditioner outer unit connecting pipe.

Preferably, the air conditioning system is a dual-temperature air conditioner, the windward heat exchanger in the indoor unit of the dual-temperature air conditioner is communicated with the condenser or the compressor through a first connecting pipeline of the air conditioner external unit connecting pipe, and the leeward heat exchanger in the indoor unit of the dual-temperature air conditioner is communicated with the condenser or the compressor through a second connecting pipeline of the air conditioner external unit connecting pipe.

Compared with the prior art, the invention has the following beneficial effects:

1. the air conditioner outdoor unit connecting pipe can combine a plurality of connecting pipes or liquid connecting pipes in the dual-temperature air conditioner into one, thereby simplifying the connecting pipeline structure between the outdoor unit and the indoor unit in the dual-temperature air conditioner and facilitating after-sale installation and maintenance.

2. The first connecting pipeline of the connecting pipe for the indoor unit and the outdoor unit of the air conditioner is connected with the windward side heat exchanger, and the second connecting pipeline is connected with the leeward side heat exchanger, so that the heat leakage and heat exchange temperature difference of the connecting pipe for the indoor unit and the outdoor unit of the air conditioner can be reduced, the heat leakage loss is reduced, and the operation energy efficiency of an air conditioning system is improved
