Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a coupled temperature-adjusting and dehumidifying air conditioning system. Background Art

[0002] Radiant cooling air conditioning is a cooling system based on heat radiation, supplemented by heat convection, which mainly regulates indoor temperature by transferring heat from high-energy objects directly to low-energy objects through radiation. This type of air conditioning system transfers cold energy through radiation and does not rely on air flow. Therefore, it does not have the blowing feeling of traditional air conditioning, reduces the discomfort caused by air flow, and can distribute cold energy more evenly, making the indoor temperature more balanced. However, the cooling capacity of radiant cooling air conditioning is relatively weak, and it cannot completely eliminate the indoor latent heat, and has great limitations. At the same time, when the surface temperature of the radiation panel is low, it will increase the risk of condensation indoors.

[0003] To solve the above problems, Chinese patent CN202110943456.1 proposes a heat pump air conditioner with dehumidification function, and adds a dehumidification thermostat to the cooling / heat circulation system of the cold radiation refrigeration air conditioning system. The dehumidification thermostat and the refrigeration function of the heat pump host cooperate to adjust the temperature and dehumidify, thereby achieving a synergistic effect.

[0004] In the prior art, the working conditions of the dehumidifier and thermostat are usually adjusted by detecting several parameters in the indoor environment where the dehumidifier and thermostat are placed.

DETAILED DESCRIPTION

[0025] The scheme of the present invention is described in detail below with reference to the accompanying drawings.

The air-conditioning system 100 includes a main unit 110, a water tank 120, a user-end coil 130 arranged indoors, an auxiliary unit 140 arranged indoors, and a temperature and humidity sensor 150 arranged at the user end; and a controller (not shown) electrically connected to the temperature and humidity sensor 150, the main unit 110 and the auxiliary unit 140.

[0027] The host 110 is connected to the water tank 120 through the water inlet pipe 121 and the water outlet pipe 122 to form a water circulation loop; the user-end coil 130 is connected to the water tank 120 through the water supply pipe 131 and the return pipe 132, wherein the auxiliary machine 140 is arranged on the return pipe 132 and is connected in series with the user-end coil 130 to form an indoor water circulation loop, and the indoor circulating water flows through the water tank 120, the user-end coil 130 and the auxiliary machine 140 in sequence; the water circulation loop and the indoor water circulation loop are coupled and connected through the water tank 120.

[0028] Furthermore, the water inlet pipe 121 , the water outlet pipe 122 , the water supply pipe 131 and the water return pipe 132 are respectively provided with stop valves; and the water supply pipe 131 is provided with a water pump.

[0029] Specifically, the host 110 centrally generates cold water, which is transported to the water tank 120 through the water inlet pipe 121 and the water outlet pipe 122 for storage so as to be used when needed.

[0030] Specifically, the auxiliary machine 140 has two working modes: refrigeration and dehumidification. The refrigeration system can generate a low-temperature environment or cooling medium to meet the cooling demand. It also has advanced dehumidification technology to effectively remove moisture from the air and reduce the humidity level.

[0031] In this embodiment, the main unit 110, the water tank 120, the user-end coil 130 and the auxiliary unit 140 are not the invention improvements of this application, and their specific internal structures are not limited in this application.

[0032] Specifically, the temperature and humidity sensor 150 is set in an indoor environment including the user-end coil 130 and the auxiliary machine 140. Its specific location is not limited. It is mainly used to detect the actual temperature T0 and humidity Q0 at the user end, and transmit the actual temperature T0 and humidity Q0 to the controller.

[0033] For details, please refer to Figures 2 to 3 The controller in the coupled air conditioning system of the present invention includes a control device 20 for the working status of the main machine and the auxiliary machine based on the temperature and humidity at the user end, specifically including an actual temperature and humidity acquisition unit 21, a temperature and humidity comparison unit 22 and a main machine and auxiliary machine working status control unit 23.

[0034] The actual temperature and humidity acquisition unit 21 is used to execute step S10: continuously acquire the actual temperature T0 and actual humidity Q0 of the user terminal.

[0035] The temperature and humidity comparison unit 22 is used to execute step S20: respectively determine the difference between the actual temperature T0 and the set temperature TS, and the difference between the actual humidity Q0 and the set humidity QS, to determine that the user terminal is in the environment.

[0036] Specifically, step S20 includes the following method:

[0037] If the actual temperature T0 is greater than the set temperature TS and the actual humidity Q0 is greater than the set humidity QS, the user end is in a high temperature and high humidity environment;

[0038] If the actual temperature T0 is greater than the set temperature TS and the actual humidity Q0 is less than the set humidity QS, the user end is in a high temperature and low humidity environment;

[0039] If the actual temperature T0 is less than the set temperature TS and the actual humidity Q0 is greater than the set humidity QS, the user end is in a low temperature and high humidity environment;

[0040] If the actual temperature T0 is lower than the set temperature TS and the actual humidity Q0 is lower than the set humidity QS, the user terminal is in a low temperature and low humidity environment.

[0041] The main machine and auxiliary machine working state control unit 23 is used to execute S30: control the working state of the main machine and auxiliary machine according to the environment where the user terminal is located.

[0042] Specifically, step S30 includes the following method:

[0043] If the user end is in a high temperature and high humidity environment, the control host performs cooling and the auxiliary machine performs cooling or dehumidification;

[0044] Specifically, if the user end is in a high temperature and high humidity environment, when T0≥TS+△T, the auxiliary machine is controlled to perform refrigeration; when T0<TS+△T, the auxiliary machine is controlled to perform dehumidification; wherein △T is the allowable temperature fluctuation value, and its value range is △T∈(0.5℃,2℃); in this embodiment, the value of △T is 1℃.

[0045] If the user end is in a high temperature and low humidity environment, the control host performs cooling and the auxiliary machine performs cooling without dehumidification;

[0046] If the user end is in a low temperature and high humidity environment, the control host stops working and the auxiliary machine performs dehumidification instead of refrigeration;

[0047] If the user end is in a low temperature and low humidity environment, both the control host and the auxiliary machine will stop working.
