Description

Heat and Cold Sources of Temperature and Humidity Independent Control Air Conditioning System
Technical Field
The present invention generally relates to refrigeration and air conditioning equipments technology fields, and more particularly, to heat and cold sources of Temperature and Humidity Independent Control (THIC) air conditioning system.
Background Art
The THIC air conditioning system is directed to an air conditioning system composed of an independent sensible heat processing system for indoor temperature control and an independent latent heat processing system for indoor humidity control. Due to its advantages on improving performance of conditioning system, reducing energy consumption, improving indoor air quality, and protecting atmosphere, the THIC air conditioning system is more and more widely applied in recent years. China patent CNl 862123 A provides high efficiency liquid desiccant fresh air handling units driven by heat pump. On one hand, the fresh air units cool the desiccant concentrated solution with an evaporator of a heat pump so as to improve the solution's capability of moisture absorption and remove the latent heat released during the moisture absorption process; on the other hand, the fresh air units heat the regenerated dilute solution with a condenser of the same heat pump, and the solution is concentrated into regenerated solution by performing a total heat exchange with the exhaust air of total heat recovery. The energy efficiency ratio (EER) of the heat pump driven liquid desiccant fresh air units provided by China patent CNl 862123 A is relatively high, thus the fresh air units has very good prospects for application. In the THIC air conditioning system mentioned below, the liquid desiccant fresh air units refers to the heat pump driven liquid desiccant fresh air units provided by China patent CNl 862123 A. Fig. 1 is a schematic diagram illustrating the working principle of the THIC air conditioning system in the prior art. The indoor sensible heat is removed by high temperature(around 18°C) chilled water from refrigerator 1, and the indoor latent heat is removed by the dry and cool fresh air from the liquid desiccant fresh air units. In the liquid desiccant fresh air units, the cooling capacity required by the liquid dehumidifier and the heating capacity required by the liquid regenerator are provided by refrigerator 2. The refrigerator 1 and refrigerator 2 can be regarded as the heat and cold sources of the THIC air conditioning system. For the heat and cold sources of the THIC air conditioning system in the prior art, the refrigerator 1 is usually a centrifugal or screw refrigerator with a relatively large cooling capacity, and the refrigerator 2 is usually a vortex refrigerator with a relatively small cooling capacity. A centrifugal refrigerator is not used as the refrigerator 2, since the cooling capacity of a conventional centrifugal refrigerator is thousands of kilowatts and the cooling capacity required by the refrigerator 2 is usually below 200 kw according to the usual fresh air requirement (below 18000 m per hour). However, the refrigeration efficiency of a vortex refrigerator is usually lower than that of a centrifugal refrigerator; the rated value of a vortex refrigerator is usually 3~4 while the refrigeration efficiency rated value of a centrifugal refrigerator may be 5~6. If a centrifugal refrigerator can be made small enough with the cooling capacity level of a vortex refrigerator, the original vortex refrigerator may be replaced by a centrifugal refrigerator.
To sum up, the refrigeration efficiency of the heat and cold sources of the prior THIC air conditioning system is relatively low, and it is disadvantaged to reduce energy consumption and protect atmospheric environment.

The outlet refrigerant from the first condenser 2a passes through the first expansion valve 3a to flow into the first evaporator 4a, so as to cool the high temperature chilled water which flows on the other side of the first evaporator 4a in reverse direction from the refrigerant; the outlet refrigerant of the first evaporator 4a flows into the first compressor la, and then enters the next cycle after being processed.
In the refrigerator b, the outlet refrigerant of the second compressor lb first flows into the second condenser 2b to heat the concentrated solution which flows on the other side of the second condenser 2b in reverse direction from the refrigerant by the higher temperature of the refrigerant.

The outlet refrigerant of the second evaporator 4b flows into the second compressor lb, and then enters the next cycle after being processed.
In this embodiment, both the first compressor la and the second compressor lb are centrifugal compressors, for example, a centrifugal compressor with the cooling capacity of 175kW (Wang Jia et al., Performance analysis on micro centrifugal chillers, Heating, Ventilating & Air Conditioning, 2009, 39 ( 5 ) : 104-108).
In this embodiment, the high temperature chilled water entering the first evaporator 4a through a chilled water inlet 7 is cooled to around 18°C by the refrigerant, and then it is sent to an indoor sensible heat terminal through a chilled water outlet 8.
In this embodiment, the concentrated solution entering the second condenser 2b through a concentrated solution inlet 10 is heated to around 45 °C by the refrigerant, and then it is sent to a regenerator through a concentrated solution outlet 9.
