Embodiment Construction

[0009] The invention is a small central air-conditioning system with fresh air.

[0010] In the schematic structural diagram of a fresh air small-scale central air-conditioning system shown in FIG. 1 , the small-scale central air-conditioning system is divided into two parts: an indoor unit and an outdoor unit. The indoor unit has an air treatment terminal 3 installed indoors to directly adjust the indoor temperature. In summer, the cooling and evaporating temperature is controlled at 18° C., and an air inlet 4 and an air outlet 5 are provided indoors. Condensation and heat removal end of the outdoor unit installation system and independent fresh air unit: the condenser 6 is connected to the indoor air treatment end 3; the solution regenerator 8 is connected to the dehumidifier 10 through the solution heat exchanger 9; the plate heat exchanger 11 of the dehumidifier 10 The water pump 16 and the circulating water pipeline are connected to the evaporative cooler 14 installed at ...

Abstract

The small central air conditioning system with fresh air as one kind of air conditioning equipment consists of indoor set and outdoor set. The indoor set in the end of the air treatment has air inlet and air outlet. The outdoor set has condenser, dehumidifier, solution regenerator and solution heat exchanger connecting the dehumidifier a the solution regenerator, solution heat recoverer, evaporating cooler near the recoverer, outer fresh air inlet pipe with corresponding air inlet and air outlet, and indoor air outlet pipe with corresponding air return port and exhaust port. The present invention adopts whole heat recovering and condenser heat recovering to lower the temperature and humidity of fresh air, lower fresh air treating power consumption and raise the energy efficiency of the whole system. The present invention has no surface humidity caused by condensing dehumidification, and is one abacterial health air conditioner with comfortable fresh air.

Description

technical field [0001] The invention belongs to the field of air conditioning devices, in particular to a small central air conditioning system with fresh air. Background technique [0002] In the 20 years since the birth of my country's air-conditioning industry, it has always been a pattern of parallel development of central air-conditioning and household air-conditioning. One of the reasons is that the markets of the two are different. The applicable objects of central air conditioners are modern large buildings, such as hotels, office buildings, large shopping malls, etc., while the users of household air conditioners are families. However, in recent years, the increase of residences and duplex residences with an area of ​​more than 100 square meters and the massive development of commercial housing and villa buildings have created a demand for small central air-conditioning systems between large-scale central air-conditioning systems and household air-conditioning syste...
