Definitions

  • This invention relates to a package air conditioner which is generally used as an air conditioner for homes and every kind of offices, and it relates to a room air circulating apparatus for compulsorily circulating room air to be a temperature control medium in a room when it is used jointly with a stove provided fuels such as petroleum and gas.
  • a package air conditioner though computerized control such as a use of IC contributes greatly to improving the quality, whether a hanging type or floor type, is employed by a single circulate route form in which room air is inhaled from particular level and either heated or cooled through a heat exchange, the heated or cooled air thereafter is exhaled into a room from a particular level which does not obstruct saio air to be inhaleo.
  • most apparatuses are provided with a thermistor sensor being equipped with an inhale gate for controlling room temperature.
  • above-mentioned package air conditioner being widely used at present causes great variation of temperature in different parts of a room if it is solely employed for heating or cooling, although there is slight variance due to a setting type of an apparatus and a direction of heated or cooled air to be exhaled.
  • temperature between the upper and lower level of a room is tens to 20 degrees Celsius in winter and 5 to 10 degrees even in summer due to a draft effect causing warm air to mass near a ceiling level and cool air to stagnate around floor, and room air stays because of obstacles such as desks, charis, and counters. These conditions are unfavorable for health as well as unpleasant.
  • temperature to be determined is set higher or lower than necessary for providing pleasant temperature in a dwelling zone, which generates a great loss of energy leading to a rise in running cost.
  • Fig. 18 of a temperature distribution diagram the temperature at the upper level in a room reaches 30°C or higher, while that of the floor level is apploximately 20 0 C, presenting the large temperature variation.
  • the above-mentioned state results from that heated air ascends while cool air descends, wherein air constantly circulates at the higher level than the middle in the room and cool air in the lower level stagnates without flowing.
  • various obstacles in the room typically such as desks and chairs cause the above tendency to grow further in a real case.
  • Fig. 19 of a temperature distribution diagram blast air blown to the floor results in less variation of temperature between the upper and the lower levels than said case(l) due to less air stagnation to rise temperature of the lower level.
  • Fig. 20 of a temperature distribution diagram at the level 1m from the floor a high temperature zone is partially produced at the center of the room, which moreover is the level of a head when a man sits on a chair. Therefore, blast air at high temperature directly blown gives an unpleasant feeling or blows off papers on a desk as well as produces unfavorable condition for health.
  • Fig. 21 of a temprtature distribution diagram such large temperature variation as apploximately 20°C between the upper and the lower levels in the room, more particularly the temperature variation is larger than said 1(1) due to hot air zone at ceiling and cold air zone on floor.
  • Fig. 22 of a temperature distribution diagram an air current of 0.5m/sec or haster which gives an unpleasant feeling is generated at the central part of a dwelling zone, about 1.5m high from the floor.
  • Fig. 25 of a plane figure of an object room(R) and a cooling apparatus (A.C.) of a hanging type to be set so that air is exhaled horizontally the distribution of room temperature is measured at each cross sections of X-X, Y-Y, and Z-Z with distribution deagrams shown by Fig. 26 A,B, and C.
  • both gates of inhaling room air and exhaling blast air being located near the ceiling permit high temperarure air at the upper level to be cooled by heat exchange, which results in a dreft effect due to which exhaled cool air descends naturally. Therefore, the temperature variation in the room is as ideal as apploximately 1°C at any part.
  • the downward direction for exhaling air is desirable to promote a cooling effect in a dwelling zone where blast air (cool air) directly hits. Therefore, the temperature variation and a cooling effect in a dwelling zone contraoict each other.
  • the invention is intended to provide a room air circulating apparatus which can realize pleasand and healthy heating and cooling by means of uniformalized and suitable room temperature even when it is employed jointly with various types of stove as well as with said package air conditioner.
  • a room air circulating apparatus to be developed in order to attain the object mentioned above is so constructed as to inhale room air and exhale said inhaled air into a room, and the room air circulating apparatus comprising a hollow case in a box shape provided with an inhale gate for room air at least at a lower end of either an upper end or a lower end of the hollow case, a spout gate provided at an upper part of said hollow case in a box shape for exhaling inhaled air to a room, and a fan built in said hollow case in a box shape for inhaling and exhaling air.
  • a room air circulating apparatus which is characterized in the manner mentioned above provides hereinafter operations.
  • angles of exhaling cool or hot air from the package air conditioner and of exhaling room air from the circulating apparatus are set slightly upward from a horizontal plane, so that mixed air is situated at the level higher than a dwelling zone, resulting in flowing at high velocity. Hot air, being involved, generates lenient return air to be inhaled into this circualting apparatus.
