Problems solved by technology

Heating with fresh air all-in-one unit has a strong sense of wind. While diluting the indoor air, it is easy to mix the new and old indoor air, which interferes with the airflow direction and is not energy-saving enough.

Embodiment 1

[0027] see Figure 3 to Figure 4 , as shown in the legend therein, a passive house with radiant cooling and heating includes a sealed and insulated room body 10, an air supply system 20 for inputting fresh air into the inside of the sealed and insulated room body 10, and a sealed and insulated room body 10 containing Exhaust system 30 for exhausting stale air, ventilation heat recovery system 40, ambient source heat exchange system 50, and cooling and heating system. The above ambient source heat exchange system 50 includes a fluid delivery device 51 for heat exchange with the natural environment , the inlet of the fluid delivery device 51 communicates with the closed internal circulation fluid 52, the fluid output by the fluid delivery device 51 exchanges heat with the air in the sealed heat preservation room body 10 and / or the fluid delivered by the fluid delivery device 51 is sent into the sealed heat preservation room The air in the body 10 performs heat exchange;

Embodiment 2

[0045] see Figure 5 , as shown in the legend, the rest is the same as the first embodiment, the difference is that there is a personnel gathering zone distributed in the sealed and heat-insulated room, and the fresh air sending end is set on the ground or corner of the sealed and heat-insulated room or the lower end of the wall, and the stale air The receiving end is arranged on the top wall or the upper end of the wall of the airtight heat preservation room body.

[0046] In this embodiment, in a small office / room, cool air with a speed of less than 0.2m / s is sent from the bottom of one side of the room, through the heat radiation at the bottom, and the heat provided by the heat source of the human body in the room. The hot and dirty air together reaches the top area of ​​the ceiling and then exits the room over the other side. There is almost no polluting gas in the work area, avoiding indoor cross-infection and improving the health of the indoor environment, which can eff...

Abstract

The invention discloses a radiation type refrigerating and heating passive house, which comprises a sealed heat insulating house body, an air supply system, an exhaust system, a ventilation heat recycling system, an environment source heat exchange system and a refrigerating and heating system, wherein the environment source heat exchange system comprises a fluid conveying device which exchanges heat with a natural environment; the refrigerating and heating system comprises an indoor refrigerating and heating device used for refrigerating or heating the interior of the sealed heat insulating house body to a set temperature; and the indoor refrigerating and heating device is a radiation type refrigerating and heating device. According to the radiation type refrigerating and heating passive house disclosed by the invention, when heat compensation or cold compensation is required in winter or in summer, a technical system of radiation heat compensation or cold compensation is used, so that interference to airflow direction is reduced through large-area uniform radiation, a higher comfort level is achieved, and more energy is saved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a passive house with radiant cooling and heating. Background technique [0002] Professor Adamson of DeLong University in Sweden and Dr. Fest of Germany first proposed the concept of passive house in 1988. properties to maintain a comfortable interior thermal environment for the building. In 1991, the first "passive house" was built in Darmstadt, Germany. Then Dr. Fest established the "Passive House" Institute (PHI) in Darmstadt, Germany in 1996. In 2015, the German Passive Research Center further improved the certification standards for passive houses, which are divided into three levels: "Classic", "Plus" and "Premium". The latest 2020 version of Germany's "Building Energy Law" stipulates that there are three requirements for near-zero energy buildings: 1) The energy consumption of heating, cooling, ventilation, hot water lighting, etc. of the build...
