Total fresh air high-efficient energy-saving central air conditioning system using off-peak power for operating main engine

Abstract

The invention discloses a total fresh air high-efficient energy-saving central air conditioning system using off-peak power for operating a main engine, which comprises the main engine, an air cooler coil, an air inlet pipeline and an air outlet pipeline; the air cooler coil is provided with an air inlet, an air outlet, a fan and a water cooling coil; the main engine comprises a large heat insulating water reservoir, a water pump and an energy cycling system which mainly comprises a compressor, an evaporator and a condenser; the large heat insulating water reservoir is provided with a water replenishing opening and two pairs of inlets and outlets; wherein one pair of inlet and outlet are communicated with an inner cavity of the evaporator outside the coil, and the other pair of inlet and outlet are connected with the water cooling coil; and the whole air conditioning system also comprises a fresh air pretreatment device. The main engine of the system operates at night, and the air conditioner of the air cooler coil is used during the day, thus leading the main engine with high energy consumption to stagger the power consumption peak in the daytime, which can multiply reduce the cost; and simultaneously, all or part of the inlet air of the air cooler coil is fresh air coming from the outside, therefore, the indoor environment is characterized by being environment-friendly, comfortable and healthy.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to a fresh air, high-efficiency and energy-saving central air-conditioning system that utilizes off-peak electricity to run a main engine. Background technique [0002] At present, the central air-conditioning system of the water system such as figure 1 As shown, it mainly includes a main engine 1', a cooling fan coil unit 2', an air inlet duct 3' and an air outlet duct 4', wherein the main engine 1' is composed of a compressor 11', a condenser 12', and an evaporator 13'. The cooling fan coil 2' is provided with an air inlet 21', an air outlet 22', a fan 23' and a water cooling coil 24', one end of the air inlet pipe 3' is connected to the air outlet 22' of the cooling fan coil, and the other One end is connected to the cooling room 5', one end of the air outlet duct 4' is connected to the room 5', and the other end is connected to the air inlet 21' of the cooling fan coil for r...
