Dutch Alley song Hangzhou air conditioning repair company phone ╭89328785 | 85232113╭ Dutch Lane air conditioning repair Hangzhou song + selection conditioning system, should take full account of the use of the occasion, the use of the characteristics and requirements of owners and other factors. Zhao Jing Fang Desheng mark Gudang Caihe Tong Tsui East New Park North Garden. Air conditioning load is calculated as a reasonable choice of air terminal handling equipment and determining the cold, heat, equipment capacity to provide evidence. Air conditioning load calculations include summer cooling load calculation and winter heat load calculations. In the design phase, the load can be used to calculate the estimated load index. In the construction design stage, according to regulatory requirements, respond to each air-conditioned room of the hourly load calculation itemized. When determining the air conditioning load, for residential load mainly to envelope the room. At the same time, the load should be considered when the temperature difference between the heat transfer due to the next room without air-conditioning. For winter intermittent operation, which results in easy and low freezing temperatures outside regional systems can be an evaporator and circulating pump and which consists of indoor outdoor host separate auxiliary. Indoor and outdoor auxiliary refrigerant pipe connecting the host. In cold areas, winter outdoor temperature is low, according to the choice of the cooling load in summer water chiller, heat for winter heating load in winter often can not meet the requirements, you should consider using auxiliary heating to increase the supply of heat. When determining the total load of the air conditioning system, should take full account of the particularity of residential use. Mainly by residential bedroom, living room, dining room, kitchen and bathroom composition, kitchen and bathroom are generally no air conditioning, and the bedroom, living room, dining room while a small air conditioning accounts probability nearby. Dutch Alley song Hangzhou air conditioning repair company phone so using low coefficient of 0.5 to 0.7 can generally choose. (1) air-conditioning duct system duct air-conditioning systems are less able to adjust the load, the unit is stopped from the return air compressor according to the parameter control. Air supply units are generally not vary with room air conditioning load changes, when a room needs air nearby, other unwanted air-conditioned rooms also have air into. Monolithic unit should be as close to the service area is arranged so that the return air duct as short and straight. As the air handling equipment placed in monolithic unit, introducing fresh air is very convenient. For lower-storey air-conditioned areas, such as residential, as arranged in the main duct hallway, living room surrounding for decorative treatment, should be located on the manifold air flow control valve. Outlet to deliver double-Grille side mainly, but also according to decorating needs, Qu Dutch Lane Hangzhou air conditioning repair company phone uses to send top diffuser vent or fissure type vents and so on. (2) air source water chiller air source water chiller compressor is divided into two kinds of fixed and variable speed. For constant speed chiller, compressor indoor load change is likely to cause frequent starting and stopping, as a result of small-scale water systems should consider the thermal stability requirements of the system, so as to avoid frequent start compressor at part load. Therefore, the value should be set based storage tank, or to increase the supply and return water temperature of the system. How can the outdoor air duct system compressor and a condenser composed typhoon cold, the indoor unit is composed of an evaporator and circulating fan, whose number of units and the same number of compressor units, in many forms, such as ceiling type, hidden ceiling type and so on. The system features an outdoor condenser unit near the air cooling, each one compressor and indoor unit configured to form an independent system, between the condenser and the evaporator of the indoor unit song Dutch Lane air conditioning repair company in Hangzhou phone outdoor unit Connection unified management of up to 25m, hidden smallpox machine (indoor unit) can anemometer according to the interior pipe and outlet conditions can even be arranged in the room, but also access to the new introduction of new air duct system totally dependent on refrigerant cycle complete air conditioning requirements, the system uses both split air-conditioning functions and is central air blast effects. As the name suggests is a refrigerant system, it is transported to the vicinity of the compressed refrigerant medium, the use of a compressor driven by a plurality of indoor unit, outdoor unit main body by the outer heat exchangers, compressors, and other accessories. The indoor unit by direct evaporative heat exchangers and fans. The refrigerant supplied to the outdoor unit through a pipe routing indoor unit, controls the flow rate of the refrigerant pipe and into the vicinity of each indoor radiator cooling flow, to meet different load requirements of the room to heat and moisture. The main refrigerant air conditioning systems and other differences are: The compressor system with frequency control to control song Dutch Lane air conditioning repair company in Hangzhou phone when the system is in a low load, the compressor speed by inverter controller, so the system able to change the flow of refrigerant circulating nearby, thereby automatically control the cooling capacity to meet the requirements of the general residential home air conditioning system just set a variable speed compressor. Water control in general, there are three ways: First, change the way traffic flow mode is controlled by the room thermostat is turned on the electric two-way valve on the outlet of the unit on or off, when the fan coil stops, the valve is closed. Installation of air conditioning repair company phone air-conditioning water mains song Dutch Lane Hangzhou pressure bypass valve to stabilize the incoming traffic unit. Second, the constant flow mode, constant flow mode is turned on or off by the room thermostat to control the electric three-way valve on the outlet unit; the third is placed in a mixed way traffic between fixed and variable flow, the ways of the neighborhood, part of the crew from the host near the use of electric two-way valve, the other three-way valve unit is used, then you can dispense with pressure bypass valve, used in this way should pay attention to two-way valve is equipped with a number of three-way valve. Three-way valve amount is too small, there is likely to lead to a host of water flow is too low due to downtime. When there is a certain degree of supercooling of the liquid refrigerant entering the capillary tube, will occur along the flow direction of the pressure change of state, with pressure subcooled liquid into saturated liquid gradually decrease the corresponding pressure, known as the liquid phase section, its pressure is not and changes linearly. When the pressure falls below its corresponding saturated pressure, it is necessary to produce flash hair phenomenon, so that evaporative cooling of the refrigerant liquid itself, i.e., with decreasing temperature of the refrigerant pressure reduced accordingly. The flow rate of the refrigerant through the capillary increases with inlet pressure increases, while with the decrease of the evaporator pressure increases, when the limit is reached, the flow changes with the pressure no longer increases.
