The working principle of the air conditioner coil pipe is as follows: by means of the fan, air is cooled or heated after passing through the cold water or hot water coil pipe and then is sent into the room, so that the temperature of the room is kept within a comfortable temperature range.
When the dehumidifier and the air conditioner coil are independently arranged, two sets of equipment are respectively required to be provided with corresponding supporting facilities such as a corresponding air duct, a fan, an air outlet air duct and the like, so that the installation process is complex and the cost is high.
In order to solve the above-mentioned problems, the present utility model provides an indoor unit and an air conditioner, and fig. 1 is a schematic structural diagram of an embodiment of the indoor unit provided by the present utility model.
Referring to fig. 1, the indoor unit 100 includes a casing 10, a dehumidifying device 20, and an indoor heat exchanger 30, a heat exchange air duct 13 is formed in the casing 10, the casing 10 is provided with an air return port 11 and an air blowing port 12, and the heat exchange air duct 13 is communicated with the air return port 11 and the air blowing port 12; the dehumidifying device 20 is arranged in the heat exchange air duct 13, a refrigerant circulation loop is formed on the dehumidifying device 20, the dehumidifying device 20 comprises a compressor 21, an evaporator 22 and a condenser 23 which are sequentially arranged in series in the refrigerant circulation loop, the evaporator 22 is arranged on the windward side of the heat exchange air duct, and the condenser 23 is arranged on the air outlet side of the heat exchange air duct; the indoor heat exchanger 30 is disposed in the heat exchange air duct 13 and is spaced from the dehumidifying device 20, so as to exchange heat with air flowing through the heat exchange air duct 13.
In the technical scheme provided by the utility model, the dehumidifying device 20 and the indoor heat exchanger 30 are simultaneously arranged in the heat exchange air duct 13 of the shell 10, so that the dehumidifying device 20 and the indoor heat exchanger 30 can share the same air duct, and only one set of corresponding supporting facilities such as a fan 50, an air inlet air duct and the like are required to be arranged, and compared with the existing scheme, the system integration level is higher; a group of corresponding supporting facilities such as fans 50, wind inlet pipes and the like can be saved, an electric control system and components are saved, initial investment is saved, and installation space in a ceiling is reduced.
It should be noted that, the dehumidifying device 20 includes a compressor 21, an evaporator 22 and a condenser 23 sequentially connected in series in the refrigerant circulation loop, the evaporator 22 is disposed on the windward side of the heat exchange air duct, and the condenser 23 is disposed on the air outlet side of the heat exchange air duct, so that the air flowing in the heat exchange air duct 13 is cooled to below the dew point temperature by the evaporator 22, and the liquid water is condensed, so that the dehumidification of the air is realized, and the temperature is raised to the original temperature after the air is heated by the evaporator 22, so that only dehumidification is realized, and the air flow temperature in the heat exchange air duct 13 is not changed greatly. At this time, the indoor heat exchanger 30 is matched to adjust the temperature, so as to adjust the air flow temperature of the heat exchange air duct 13, and the indoor unit 100 can independently adjust the humidity and the temperature.
It should be emphasized that the dehumidification device 20 is capable of independently performing dehumidification by the refrigerant supplied from the compressor 21 itself, and the dehumidification system using the compressor 21, the evaporator 22, and the condenser 23 is better in dehumidification efficiency than the conventional adsorption type dehumidification system.
The indoor heat exchanger 30 is connected to the outdoor unit, and cools by means of an external cold source, and does not share the cold source with the dehumidifier 20, and the cold sources are relatively independent, so that the phenomenon of mutual interference between the two is avoided.
In this embodiment, the relationship between the motor rotation speed and the frequency: n=60 f/P (1-S), f-supply frequency, hz, P-pole pair number, rotation speed of n-motor, r/min, S-slip, slip s=0 when synchronizing the motor;
q=f (m); q-dehumidification amount, m-refrigerant mass flow, so that under certain working conditions, the refrigeration amount is in direct proportion to the refrigerant mass flow:
m=f (n), f-refrigerant mass flow as a function of compressor 21 speed, n-compressor 21 speed, therefore, under certain conditions, refrigerant mass flow is in direct proportional function with compressor 21 speed.
From the above analysis, the frequency of the compressor 21 is proportional to the amount of dehumidification. If the monitored humidity is higher than the upper limit value of the indoor design humidity, transmitting a signal to the variable frequency compressor 21 of the dehumidification system, wherein the operating frequency of the variable frequency compressor 21 is increased, the dehumidification amount is increased, and the humidity of the treated air is reduced; similarly, if the detected actual humidity is within the indoor set humidity range, the operation frequency of the compressor 21 is reduced; if the monitored humidity is lower than the indoor design humidity lower limit value, the compressor 21 stops operating, thereby realizing the adjustment of indoor humidity.
Meanwhile, the position between the indoor heat exchanger 30 and the dehumidifier 20 is not limited, that is, the indoor heat exchanger 30 is disposed on one side of the dehumidifier 20 near the air blowing port 12, so that air enters the heat exchange air duct 13 from the air return port 11, passes through dehumidification of the dehumidifier 20, is then subjected to temperature regulation by the indoor heat exchanger 30, and the dehumidified and temperature-regulated air is blown out from the air blowing port 12, so as to meet the requirements of users on the temperature and humidity of the indoor environment.
Of course, the indoor heat exchanger 30 may be disposed on a side of the dehumidifier 20 near the return air inlet 11, at this time, air enters the heat exchange air duct 13 from the return air inlet 11, and passes through the cooling of the indoor heat exchanger 30 first, at this time, the precooling of the air is achieved, on the one hand, when the air is cooled again by the evaporator 22 of the dehumidifier 20, the temperature of the air can be cooled down, so that the condensation efficiency of water in the air is improved, the dehumidification efficiency is improved, and on the other hand, the air can be cooled down and cooled down to the compressor 21, so as to avoid the occurrence of the phenomenon of high-temperature protection of the compressor 21.
Of course, it is also possible that a plurality of indoor heat exchangers 30 are provided, and a plurality of indoor heat exchangers 30 are separately provided on both sides of the dehumidifying device 20, and air enters the heat exchange air duct 13 from the return air inlet 11, passes through the cooling of the indoor heat exchangers 30 first, achieves precooling of the air, passes through the dehumidifying of the dehumidifying device 20, is then subjected to temperature regulation by the indoor heat exchangers 30, and the dehumidified and temperature regulated air is blown out from the air outlet 12, thereby more efficiently completing the regulation of the humidity and the temperature of the indoor air.
Meanwhile, the plurality of indoor heat exchangers 30 may be respectively corresponding to different outdoor units, or may be corresponding to the same outdoor unit, which is not limited herein, in this embodiment, the indoor unit 100 further includes a refrigerant inlet pipe 40 and a refrigerant return pipe 41, the plurality of indoor heat exchangers 30 are disposed, the refrigerant inlets of the plurality of indoor heat exchangers 30 are communicated with the refrigerant inlet pipe 40 through pipes, and the refrigerant outlets of the plurality of indoor heat exchangers 30 are communicated with the refrigerant return pipe 41 through pipes, so that by disposing the refrigerant inlet pipe 40 and the refrigerant return pipe 41, one outdoor unit can simultaneously provide refrigerant for the plurality of indoor heat exchangers 30, thereby saving cost.

Specifically, the formula: the cooling capacity of the water side is calculated according to the following formula:
Q＝WCPW(TW2-TW1)-E (1)
w-water supply amount, kg/S;

TW1, TW 2-the temperature of the cold (or hot) water entering and exiting the tested fan 50 coil, DEG C; e-inputting the total power W of the tested fan 50 coil;
cooling capacity of water side, W;
As can be seen from the formula (1), the cooling capacity and the water supply capacity of the indoor heat exchanger 30 are proportional, the relative opening of the valve is proportional to the water flow rate passing through the valve, and the conclusion ① can be obtained: the relative opening of the regulator valve 42 is proportional to the refrigeration capacity of the coil of the evaporator 22. If the monitored temperature is higher than the upper limit value of the indoor design temperature, transmitting a signal to the regulating valve 42 on the refrigerant inlet pipe 40 of the indoor heat exchanger 30, wherein the relative opening degree of the regulating valve 42 is increased, the refrigerating capacity is increased, and the indoor temperature is reduced; if the monitored temperature is within the indoor design temperature range, the relative opening degree of the regulating valve 42 is reduced, and the refrigerating capacity is reduced; if the monitored temperature is below the indoor design temperature lower limit, the regulator valve 42 is closed.
