But the energy consumed by the hvac system is also very staggering. In China, the proportion of building energy consumption in total energy consumption is larger and larger, the building energy consumption occupies 30% of the national total energy consumption at present, and in the building energy consumption, the energy consumed by a heating, ventilating and air conditioning system occupies 30% -50% of the total energy consumed by a building, and tends to increase year by year, even reaches more than 50% of the total energy consumption of the building. Therefore, the research on the energy-saving scheme of the air conditioning system has important economic and social benefits. Among many factors influencing the energy consumption of the air conditioning system, the optimization control of the air conditioning system is an important aspect, if advanced system optimization control energy-saving technology is vigorously developed and popularized and applied, the existing air conditioning system can completely save 20% -50% of energy, and under the current global energy shortage large form, especially under the domestic large environment greatly advocating energy saving of the whole people, the air conditioning system has great practical significance for solving increasingly sharp energy and environmental problems.
The prior patent with the publication number of CN102177400B discloses an air conditioning system for heating ventilation. The heating ventilation air conditioner can coordinate and preferentially process the temperature areas or the rooms with higher priority by setting the priority distribution of the controllable temperature areas or the rooms, so that the temperature with higher priority can reach the set temperature value in a shorter time.
The above prior art solution has the following drawbacks: indoor heat is lost at a higher speed, and energy is wasted.
Disclosure of Invention
The invention aims to provide an energy-saving system of a heating ventilation air conditioner for a building in a cold region, which has the advantage of low heat loss speed in the building.

Through adopting above-mentioned technical scheme, because the heat that only passes through warm district to the form of natural conduction can't make the heat in comfortable district reach suitable scope value, consequently through the intercommunication mouth with warm heat partial to the quick transmission in comfortable district in warm district. When the temperature reaches the requirement, the communicating port is closed, so that the heat in the warm area is not lost outwards any more.
The invention is further configured to: the central air-conditioning system is characterized by further comprising an air circulation module, wherein the air circulation module comprises an exhaust pipe connected with the comfortable area and an air chamber connected with the other end of the exhaust pipe, and air in the central air-conditioning extracted air chamber is heated and then conveyed to the warm area.
Through adopting above-mentioned technical scheme, carry warm district after extracting the heating with the air extraction in the comfortable district of exhaust tube through the air cycle module. The air in the comfortable area is extracted as the source air for heating, and the air in the comfortable area is cleaner and contains less bacteria because the comfortable area and the outside air are partially circulated; meanwhile, because the initial temperature of the air in the comfort zone is higher, the energy consumed when the air is heated to reach the required temperature is less, and the energy is saved more.
The invention is further configured to: the exhaust tube is provided with a dust filter, and an ultraviolet lamp is arranged in the air chamber.
Through adopting above-mentioned technical scheme, further dust content in the air after filtering through dust filter improves the air quality, simultaneously because the air humidity in cold areas is lower, consequently also lower with the air humidity in the comfortable district of external part intercommunication. The ultraviolet lamp is used for sterilizing and purifying air, and the ultraviolet lamp can play a good sterilizing effect in a dry and dust-less environment.
The invention is further configured to: the air conditioner further comprises a humidity control module, wherein the humidity control module comprises a humidifier arranged on the air inlet pipe and a humidity sensor arranged in the warm area, and when the humidity detected by the humidity sensor is smaller than a set value, the humidifier works to humidify.

The heat in the warm area 1 is conducted outwards and enters the comfortable area 2, so that the temperature in the comfortable area 2 is raised to a state between the warm area 1 and the outside temperature, and people can not be supercooled when walking to the positions of the passageway and the stairs.
As shown in fig. 1 and 2, a first temperature sensor 9 is installed in the warm area 1, a second temperature sensor 10 is installed in the comfort area 2, the temperature in the warm area 1 is detected by the first temperature sensor 9, and the temperature in the heat-retaining chamber is detected by the second temperature sensor 10. An air vent for communicating the warm area 1 and the comfortable area 2 is formed between the warm area and the comfortable area, and an electrically opened and closed air vent door 11 is installed at the air vent. When the first temperature sensor 9 detects that the temperature of the warm area 1 is lower than a set value, the central air conditioner 8 conveys hot air into the warm area 1 through the air inlet, so that the temperature of the warm area 1 is increased; when the first temperature sensor 9 detects that the temperature of the warm area 1 reaches a set value, the central air conditioner 8 stops conveying hot air into the warm area 1, and energy consumption is saved. When the second temperature sensor 10 detects that the temperature of the comfort zone 2 is lower than the set value, the vent door 11 is opened, so that the hot air in the warm zone 1 enters the comfort zone 2, and the temperature of the comfort zone 2 is increased; when the second temperature sensor 10 detects that the temperature of the comfort zone 2 reaches the set value, the vent door 11 is closed, so that the hot air in the warm zone 1 is not directly delivered to the comfort zone 2.
As shown in fig. 1 and 2, the air circulation module 5 includes an air exhaust pipe 12 connected to the comfort zone 2, and an air chamber 13 connected to the other end of the air exhaust pipe 12, and the central air conditioner 8 extracts air in the air chamber 13 to heat and then delivers the air to the warm zone 1. The air suction pipe 12 is provided with a dust filter 14 for filtering dust in the air, and an ultraviolet lamp 15 for sterilizing and purifying the air is provided in the air chamber 13. The air in the comfortable area 2 is extracted as the source air for heating, and the air in the comfortable area 2 is cleaner and contains less bacteria because the comfortable area 2 can be partially circulated with the outside air; meanwhile, because the initial temperature of the air in the comfort zone 2 is higher, the energy consumed when the air is heated to reach the required temperature is less, and the energy is saved more. The air humidity of the comfortable area 2 is low, the dust content in the air is further reduced after being filtered by the dust filter 14, and the ultraviolet lamp 15 can play a good sterilization effect in a dry and dust-less environment.
As shown in fig. 1 and 3, the humidity control module 4 includes a humidifier 17 installed on the air inlet duct 7 and a humidity sensor 16 installed in the warm zone 1, and the humidifier 17 operates to humidify when the humidity detected by the humidity sensor 16 is less than a set value. The air inlet pipe 7 comprises a mounting pipe 18 close to the air inlet, and the mounting pipe 18 comprises a first vertical section 19, a second vertical section 20 and a transverse section 21 connecting the lower ends of the first vertical section 19 and the second vertical section 20. Horizontal section 21 slope sets up and links to each other the end with the vertical section 20 of second and be the lower end, and trap 22 is installed to the lower end of horizontal section 21, discharges the vapor of condensation through trap 22, avoids the inside long-term ponding of pipeline to lead to breeding the bacterium.
