Embodiment 1

[0028] An integrated multi-connected high-temperature air-conditioning unit with fresh air, including a multi-connected external unit 1, a multi-connected internal unit 2, and an outdoor fresh air processor 3; a multi-connected external unit 1, a multi-connected internal unit 2, and an outdoor fresh air processor 3 are equipped with air pipe interface and liquid pipe interface, and the air pipe interfaces of multi-line external unit 1, outdoor fresh air processor 3 and multiple multi-line indoor units 2 communicate with each other through refrigerant pipelines; multi-line external unit 1 1. The liquid pipe interfaces of the outdoor fresh air processor 3 and the multiple multi-line indoor units 2 communicate with each other through refrigerant pipelines.

[0029] The main structure of the multi-connected outdoor unit 1 includes a multi-connected compressor 11 located in the outer casing, a fresh air compressor 12, an outdoor unit heat exchanger 13, an outdoor fan 14, and an exte...

Embodiment 2

[0035] Compared with Embodiment 1, this embodiment can precisely control the outlet air temperature and humidity of the fresh air. For this reason, a reheating heat exchanger 43 and a humidifier 44 are added at the rear end of the air passage of the fresh air heat exchanger 37. A reheat regulating valve 45 is added in the refrigeration cycle. In the cooling mode, the air conditioner can reheat low-temperature air with the exhaust air from the multi-line compressor 11 and the fresh air compressor 12 through the reheat heat exchanger 43, and adjust the outlet air temperature through the reheat regulating valve 43 to avoid the temperature of the air outlet being too low . And the humidity of the outlet air can be precisely controlled by the humidifier 44 .

Embodiment 3

[0037] Compared with Embodiment 2, this embodiment is a water-cooled multi-connected air conditioner unit, and the cooling water is used to dissipate heat in the cooling mode. Therefore, the outdoor heat exchanger 20 in the multi-connected outdoor unit 1 of this embodiment is a refrigerant-water heat exchanger. The casing of the multi-line outdoor unit 1 is provided with a water inlet port 18 and a water outlet port 19, and the external water source is connected to the outdoor unit 1 through these two ports.

[0038] Common types of refrigerant-air heat exchangers involved in the above embodiments are finned tube heat exchangers, micro-channel heat exchangers, and the like. Common types of the refrigerant-water heat exchangers involved in the above embodiments are plate heat exchangers, tube-and-tube heat exchangers, and shell-and-tube heat exchangers.

Abstract

The invention discloses an integrated multi-connected high-temperature air conditioning unit with a fresh air handling function. The whole unit is composed of a refrigeration system, and comprises anoutdoor unit, one or more indoor units and an outdoor fresh air handler, an air pipe connecting port and a liquid pipe connecting port are formed in each of cases of the outdoor unit, the indoor unitsand the outdoor fresh air handler, the air pipe connecting port of the outdoor unit, the air pipe connecting port of the outdoor fresh air handler and the air pipe connecting ports of the plurality of indoor units communicate with one another, and the liquid pipe connecting port of the outdoor unit, the liquid pipe connecting port of the outdoor fresh air handler and the liquid pipe connecting ports of the plurality of indoor units communicate with one another. According to the integrated multi-connected high-temperature air conditioning unit with the fresh air handling function, both returnair and fresh air can be handled at the same time, additional fresh air handling units are not needed for cooperation, and the advantages of flexible installation and small occupied area of a multi-connected air conditioning unit are reserved.

Description

technical field [0001] The invention relates to a multi-connected high-temperature air-conditioning unit, in particular to an integrated multi-connected high-temperature air-conditioning unit with fresh air. Background technique [0002] The variable frequency multi-connected air conditioning system (Variable Refrigerant Volume, VRV, multi-connected for short) usually consists of an external unit and multiple indoor units. It has the advantages of simple system, flexible control, convenient installation and maintenance, and strong reliability. It is currently the most popular One of the most popular forms of air conditioning systems. [0003] With the development of society, people's requirements for air quality are constantly improving, and fresh air has also received extensive attention. Due to the large heat and humidity load of the fresh air, it is difficult for the traditional multi-connected air conditioning unit to undertake the functions of return air treatment and ...
