商用中央空調與家用中央空調的區別 The Difference Between Commercial Central Air Conditioning and

  商用中央空調設備的結構與家用中央空調大體相同。之所以區分成商用與家用,主要由于功率差距大所形成的不同的制冷形式。家用中央空調以一體式轉子式壓縮機、螺桿式壓縮機等為主,而大型商用中央空調工程主要以離心式壓縮機和大型螺桿煙臺壓縮機為主。此外,商用中央空調系統的控制,管路的自動調控,空氣的除濕、加濕、衛生處理等要比家用中央空調復雜得多,且牽扯分戶計費等問題。
 
  The structure of commercial central air conditioning equipment and household central air conditioning is nearly the same. It is the difference in refrigeration forms due to power gap that divided into commercial and household one. As for compressor, it is mainly integral rotor compressor and  screw compressor for household central air conditioner while centrifugal compressor and large screw compressor for large commercial central air conditioning engineering. In addition, commercial central air conditioning is much more  complicated  in control system, automatic control of the pipeline, air dehumidification, humidification, medical treatment etc. than the household central air conditioning, not even mentioning the household accounting issues.

 
中央空調系統介紹 Introduction of Central Air Conditioning System

  中央空調系統 有主機和末段系統。按負擔室內熱濕負荷所用的介質可分為全空氣系統、全水系統、空氣-水系統、冷劑系統。按空氣處理設備的集中程度可分為集中式和半集中式。按被處理空氣的來源可分為封閉式、直流式 、混合式(一次回風 二次回風)。主要組成設備有空調主機(冷熱源)、風柜、風機盤管等等。
 
  The central air conditioning system consists of master and terminal system. It can be divided into entire air system, entire water system, air -water system and refrigerant system according to the medium burdening indoor heat and  wet load. According to the concentration of air handling equipment it can be divided into centralized type and semi centralized type. According to the source of treated air it can be divided into closed type, DC type, mixed type (once return air/twice return air). The main components of air conditioning are master(cold/heat source), hood, fan coil etc..

 
風冷熱泵機組工作原理 The Operational Principle of Air Source Heat Pump Unit

  該系統主要風冷熱泵主機和風機盤管末端兩大部分組成。風冷熱泵機組與風機盤管共同使用,前者提供冷水或熱水,后者將冷水或熱水,通過熱交換,吸出冷風或熱風。風冷熱泵機組是空調系統中的主機,由于采用風冷冷凝器不需要冷卻塔;而蒸發器是水冷的,夏天制冷時提供冷水,冬季制熱時提供熱水,風機盤管是空調系統的末端裝置,裝在室內如同把水從低處提升到高處而采用水泵那樣,采用熱泵可以把熱量從低溫抽吸到高溫。
 
  Air source heat pump unit mainly consists of two parts: air-cooled heat pump unit and end fan coil, which work together. The former supply cold water/hot water then cold air/hot air will be sucked out from water by the latter through heat exchanger. As the master of an air conditioner system, air-cooled heat pump unit uses air-cooled condenser instead of cooling tower. Besides, the evaporator is a water cooled one. Cold water is supplied in summer when it cooling and hot water is supplied in winter when it heating. The fan coil, as the terminal device in the system, is installed indoor. Heat of the air is sucked from low temperature area to high temperature area with the help of heat pump just the same as the water flow from low place to high place with a water pump.

 
水冷式冷水機組介紹 Introduction of Water-cooled Chiller

  對大中型空調系統而言,水冷式冷水機組是采用得最為普遍得冷源。水冷式空調,顧名思義是通過水蒸發的同時會吸收周圍熱量這一物理性質來達到降溫的效果。水冷式空調除降溫功能外,還具備通風換氣、除塵、除味等效用。是目前企業車間、公共場所、商業娛樂場合等最常用的通風、降溫設備。
 
  水冷式冷水機組與風冷式冷水機組在制冷方式與設備功能方面是完全相同的,兩者可互相兼容。所不同的是,兩者冷凝器的冷卻方式不同。水冷式機組一般采用殼管式冷凝器,以水為冷卻介質;而風冷式機組采用翅片式冷凝器,直接以空氣為冷卻介質。
 
  Water-cooled chiller is the most common cooling unit for medium and large air conditioning systems. Water-cooled air conditioning, as the name suggests, achieves cooling effect by the physical properties that is the evaporation of water will absorb heat around. In spite of cooling function, water-cooled air conditioning contains other functions such as ventilation, dust-off, odor remove etc. It is at present the most common ventilation & cooling equipment  for enterprise workshop, public place and commercial entertainment place.
 
  Water cooled chiller and air cooled chillers are exactly the same in the refrigeration form and equipment function, both of which can be compatible with each other. The difference is in the cooling form of their condenser and shell or tube condenser is normally used in water-cooled with water as the cooling medium, and air-cooled unit adopts the finned tube condenser, directly use air as cooling medium.

  The operational principle of fresh air ventilator is in this way: one side of an airtight room mechanically supplying fresh air while the other side sucking polluted air, which then caused the so called “ Fresh air flow field”. It is a kind of new environmental protection equipment keeping the indoor air clean and fresh. The replacement of independent circulatory system, eliminating indoor air pollution at the same time, supplying natural fresh air after multi- processed such as filtration, sterilization, heat, oxygen etc..

空調的匹數 The number of horses

  匹數指的是電器消耗功率,1匹=1馬力=735W,匹并不指制冷量。平時所說的空調是多少匹,是根據空調消耗功率估算出空調的制冷量。一般習慣用1匹等于 2500W的制冷量(也就是25機型),1.5匹約等于.3500的量(也就是35機型)。其余機型可以根據制冷量來估算匹數,比如50機型為兩匹。
 
  The number of horses refers to the electrical power consumption instead of refrigerating capacity . 1 horse =1 HP =735W. When referring horses of an air conditioning, it means refrigerating capacity estimated from electrical power consumption. Generally, a horse is equal to the refrigerating capacity of 2500W (25 models), and 1.5 horses is approximately equal to the refrigerating of 3500 (35 models). Also the horses of the rest models can be estimated according to the refrigerating capacity, such as 50 model for 2 horses.
