What's Air conditioning?

  From Google,we can learn that, air conditioning is a system that keeps air cool and dry.

  Air conditioning refers to the cooling and dehumidification of indoor air for thermal comfort. In a broader sense, the term can refer to any form of cooling, heating, ventilation or disinfection that modifies the condition of air. ^{An air conditioner (often referred to as AC or air con.) is an appliance, system, or mechanism designed to stabilise the air temperature and humidity within an area (used for cooling as well as heating depending on the air properties at a given time), typically using a refrigeration cycle but sometimes using evaporation, most commonly for comfort cooling in buildings and motor-cars.}

  ^{The concept of  air conditioning is known to have been applied in Ancient Rome, where aqueduct water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern  air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical  air conditioning was invented and used in 1902 by Willis Haviland Carrier.}

   An air source heat pump can provide efficient heating and cooling for your home, especially if you live in a warm climate. When properly installed, an air source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes. This is possible because a heat pump moves heat rather than converting it from a fuel, like in combustion heating systems.

   Although air source heat pumps can be used in nearly all parts of the United States, they do not generally perform well over extended periods of sub-freezing temperatures. In regions with sub-freezing winter temperatures, it may not be cost effective to meet all your heating needs with a standard air source heat pump.

  A heat pump is a machine or device that moves heat from one location to another location  using mechanical work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps for providing thermal comfort.

  Heat pumps can be thought of as a heat engine which is operating in reverse. One common type of heat pump works by exploiting the physical properties of an evaporating and condensing fluid known as a refrigerant. In heating, ventilation, and air conditioning applications, a heat pump normally refers to a vapor-compression refrigeration device that includes a reversing valve and optimized heat exchangers so that the direction of heat flow may be reversed.

Duct Air Conditioner

Split-type air conditioner prices, central air-conditioning to enjoy.
Aux Air-conditioner duct system design optimization, so to minimize the machine cost, consumers spend almost as long as the split-type air
Transfer price, you can enjoy the enjoyment of central air-conditioning.
Applicable to places
Applicable to office buildings, shopping malls, hotel lobbies, restaurants and other places.
Capacity: 12.5 ~ 55KW.
Advantages
Remote power supply system, a free air delivery configuration, and style is able to cope with the need to choose the decoration; the installation of freedom, according to the needs of the business environment, air-conditioning can be very long with 50 meters refrigerant piping, piping can be adapted to a variety of needs. Mute material the use of machine design, greatly reduce air noise; to the introduction of fresh air to improve air quality.

Summary
The purpose of the project was to build a low energy and low cost prefabricated house without compromising the comfort. Due to the overall reduced energy consumption in low energy houses the proportion of the heat required for DHW increases from 30% to 40%. This sets new requirements for a heating system. In this residence there are two air to water  heat pumps: one for heating (from October to April) and the other for DHW (DHW; all year round).

The former uses outdoor air and the latter indoor exhaust air as its heat source. The SPF of the 4.6 kW heat pump for space heating is 3.0. If auxiliaries such as fans for heat recovery and standby losses of the water heater are considered as well the SPF drops to 2.0.

Question: What is a heat pump?

Answer: Heat pumps extract low temperature energy from the environment and increases its temperature for heating purposes. Heat pump efficiencies are normally quoted as the coefficient of performance of the system, these are typically in the range 3 to 5. In other words, extracting heat from renewable sources requires just 1kW of electrical input in order to generate 3kW to 5kW of heating output. Heat pump systems therefore, are 3 to 5 times more efficient than fossil fuel boilers and are more than capable of warming a house completely, even during the lowest winter temperatures. The increasing popularity of these heating systems is reflected by their overwhelmingly successful application in the cold climates of Scandinavia.

China Palm supplies professional heat pumps.

Properly controlling moisture in your home will improve the effectiveness of your air sealing and insulation efforts, and vice versa. Thus, moisture control contributes to a home's overall energy efficiency.

The best strategy for controlling moisture in your home depends on your climate and how your home is constructed. Before deciding on a moisture control strategy for your home, you may first want to understand how moisture moves through a home.

Moisture control strategies typically include the following areas of a home:

    * Attics
    * Foundation
          o Basement
          o Crawl space
          o Slab-on-grade floors
    * Walls.

In most U.S. climates, you can use vapor diffusion retarders in these areas of your home to control moisture.

Proper ventilation should also be part of a moisture control strategy.

China Palm mainly reseach and manufacture heat pump energy-saving products and commercial air conditioners. We are professional!

Most of people can get extremely hot and very few people can get by without some form of cooling in summer.

To install air-conditioning is a major purchase, hence it is worth making sure that your money is spent as wisely as possible. This advice applies for residential (home) room air conditioning units(Either reverse cycle or cooling only). Reverse cycle air conditioners are also sometimes called heat pump air conditioners or heat pumps. For offices and other commercial air conditioning, visit commercial air conditioning.

When choosing an air conditioning system, the following are the main criteria to consider:

• Is heating required?
• Comfort level
• Purchase cost
• Running costs
• Noise levels
• Reliability
• Air conditioner brand
• Confidence in the contractor
• Outdoor unit location
