Description

Technical Field

[0001] The invention relates to the control of a fresh air air conditioner. Background Art

[0002] Fresh air equipment is used to replace fresh air in indoor enclosed spaces, and is used in homes, public places, factories or data rooms, etc. It needs to have the function of updating outdoor air to the indoor space and filtering and purifying outdoor air. When fresh air equipment is used in data rooms, the filtered and purified outdoor air introduced by the fresh air equipment discharges a large amount of heat generated by the data processing equipment in the room to the outside, achieving the temperature control of the data room, so that the equipment in the room operates within the normal temperature range. In the hot summer, due to the high temperature in the room itself, air conditioning is needed to achieve the purpose of indoor cooling. At this time, although the fresh air equipment can exchange indoor and outdoor air, it will inevitably bring outdoor hot air into the room, which will increase the air conditioning load. In addition, in winter, when the indoor and outdoor temperatures are low, the air conditioner does not need to start the cooling function, but only needs to start the fresh air equipment to exchange indoor air. Therefore, it is particularly important to automatically adjust the switch of the equipment according to the temperature. Summary of the invention

In the present invention, the fresh air system 2, the air-conditioning refrigeration system 3 and the matrix semiconductor refrigeration system 4 all form a control connection with the control terminal 1; and the control terminal 1 and the control terminal (such as a computer, a mobile phone) form a wireless connection.

[0027] In the present invention, the fresh air system 2, the air conditioning and refrigeration system 3 and the matrix semiconductor refrigeration system 4 are powered by a combined power system based on a solar power generation system 5 as the main power and conventional power as the auxiliary power; at the same time, the control end 1 controls and connects to multiple temperature monitoring systems 6 located outdoors, and through the real-time monitoring of the external temperature by the temperature monitoring system 6, the control end 1 controls the opening and closing of the fresh air system 2, the air conditioning and refrigeration system 3 and the matrix semiconductor refrigeration system 4 according to the change of temperature.

[0028] Continue watching Figure 1 In the present invention, the preferred matrix semiconductor refrigeration system 4 includes: a matrix frame structure 7 embedded between the top of the data room and the top floor in the data room, the matrix frame structure 7 is provided with 10-12 transverse independent frame structures 8 in the transverse direction, and 4-6 longitudinal independent frame structures 9 in the longitudinal direction; a semiconductor refrigeration module 10 is independently arranged in each of the transverse independent frame structure 8 and the longitudinal independent frame structure 9, and the semiconductor refrigeration module 10 is connected to the transverse independent frame structure 8 and the longitudinal independent frame structure 9 through a connecting frame and a heat insulation and waterproof layer, and the cold end of the semiconductor refrigeration module 10 is located in the data room, and the hot end of the semiconductor refrigeration module 10 is located on the top of the data room; in the present invention, the semiconductor refrigeration modules 10 are in a series structure, and the hot end of the semiconductor refrigeration module 10 is provided with a fan heat dissipation structure 11 (see Figure 2), the fan heat dissipation structure 11 is electrically connected to the solar power generation system 5 and conventional power equipment.

[0029] In actual use, the biggest problem of the semiconductor refrigeration module 10 is the heat dissipation problem at the hot end. A fan heat dissipation structure 11 is set at the hot end of the semiconductor refrigeration module 10, which can quickly dissipate the heat emitted by the semiconductor refrigeration module 10 into the air, making the use effect of the semiconductor refrigeration module 10 better.

[0030] The above structure of the present invention sets a matrix semiconductor refrigeration system 4 on the roof of the data room, and uses semiconductor refrigeration to assist the air conditioning refrigeration system 3 to cool down the inside of the data room, which not only makes the inside of the room cool down faster, but also reduces the power consumption of the air conditioning refrigeration system.

In the present invention, the semiconductor refrigeration structure specifically includes: a U-shaped fixing plate 13, which is laterally connected to the rear part of the trumpet-shaped perforation 12, and an air inlet hole 14 communicating with the trumpet-shaped perforation 12 is provided on the right side of the U-shaped fixing plate 13, and a first semiconductor refrigeration group 15 and a second semiconductor refrigeration group 16 are respectively provided on both sides of the U-shaped fixing plate 13, and the cooling ends of the first semiconductor refrigeration group 15 and the second semiconductor refrigeration group 16 are both facing inward, and the hot ends are both facing outward; and the first semiconductor refrigeration group 15 and the second semiconductor refrigeration group 16 are both controlledly connected to the control end 1.

[0032] The above structure of the present invention sets a split-type semiconductor refrigeration group at the air inlet of the fresh air system 2, which can cool the hot air about to enter the data room in summer and then send it into the data room to achieve the purpose of auxiliary cooling.

[0033] In the above structure, the reason for setting the trumpet-shaped perforation 12 with an expanded opening facing outward is that the expanded openings on the upper and lower sides of the perforation are more conducive to the hot ends at the rear ends of the first semiconductor refrigeration group 15 and the second semiconductor refrigeration group 16 to quickly dissipate heat to the external air.

[0036] The above structure of the present invention is provided with a power monitoring module in both the semiconductor refrigeration system and the air conditioning refrigeration system, which can adjust the operating status of the equipment according to the power operating parameters monitored in real time, thereby achieving the effect of energy saving and protecting the equipment.

[0037] On the basis of the above technology, the present invention then discloses a control method of the control system of the fresh air air conditioner, and the specific control method is as follows:

[0038] When the temperature monitoring system 6 detects that the outside temperature is high, the first semiconductor refrigeration group 15, the second semiconductor refrigeration group 16, the matrix semiconductor refrigeration system 4, the fresh air system 2 and the air conditioning refrigeration system 3 are driven to operate through the control terminal;

[0039] When the temperature monitoring system 6 detects that the outside temperature is low, the fresh air system 2 is driven to operate through the control terminal, and the first semiconductor refrigeration group 15, the second semiconductor refrigeration group 16, the matrix semiconductor refrigeration system 4, and the air conditioning refrigeration system 3 are turned off;

[0040] When the first power monitoring module 18 feeds back to the control terminal that the output power of the air conditioning and refrigeration system 3 is greater than the set power value, the control terminal automatically or manually sets the air conditioning and refrigeration system 3 to be partially shut down;

[0041] When the second power monitoring module 19 feeds back to the control terminal that the output power of the matrix semiconductor refrigeration system 4 is greater than the set power value, the control terminal automatically or manually sets the matrix semiconductor refrigeration system 4 to be partially closed.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
