Contact home central air conditioning and multi-residential central air conditioning MAC comparison
convert Court Building 6,QQ I do not dare to steal a few fingers to see you, a residential central air conditioning unit McQuay machine and multi-household water-line systems are compared on the nature

contrast type

together a multi-home care and more Central air conditioning (Daikin)
(indoor unit refrigerant go R22)

McQuay MAC residential central air-conditioning water system
(indoor unit to go chilled water)

air space
construction area: 180m2
conditioning area: 151 m2

outdoor cooling mechanism: 15.5 (maximum)
indoor unit total cooling capacity: see Daikin configuration table
total input power: see Daikin configuration table
number of outdoor unit: See Daikin configuration table
number of indoor unit: see Daikin configuration table
supporting air-conditioning system indoor unit auxiliary heat source can only auxiliary power, as the cell line into the family household power limit is not suitable for this form of auxiliary heat source.
Daikin load configuration table
see Huang (2004), the load configuration list.
outdoor cooling system: 19.2KW
indoor unit total cooling capacity: 34.83KW
total input power (power consumption per hour): 6.768KW
Outdoor Quantity: 1
indoor Quantity: 7 sets
auxiliary heat source (to provide hot water based): gas-fired boiler.
energy-saving low

1, the host over up to 20% with the indoor unit. The same indoor unit cooling capacity of the total load, the required 30% larger outdoor confidential. The outdoor unit's power consumption increases, the tariff increase.
2, if the union indoor and outdoor unit length or drop is large, the unit's cooling / heat attenuated; and connections over the longer gap is larger, the faster the attenuation of the unit.
1, based on characteristics of home central air conditioning, general indoor unit is not used simultaneously, so the host can choose a small cooling capacity. Super host up to 50% with the indoor unit. Host of small models that reduce power consumption, save electricity. (Not the same over with commonly used open spaces)
2, for example: in the bedroom, living room when the air conditioning is generally not open, this usage of air conditioning at the same time (the total cooling capacity outdoor / indoor cooling mechanism): 0.55
3, MAC unit uses a cold / hot water,new balance 574, the cold / hot water pipe is not the length and height restrictions will not unnecessarily with the pipe length, cold / heat loss. Indoor and outdoor unit connecting pipe length is not restricted. Installation can be adapted to the complex, flexible and convenient.
project to install

VRV units although only a few refrigerant pipe connection, but the refrigerant pipe installed in the field, the need to pay attention to water-proof, anti-air to enter,new balance mens, if the unit is mixed with water , air and other impurities, must be re-vacuum, leak detection, etc., and the refrigerant tube welding, also need special tools, oxidation-free soldering have to install complex process.
1, MAC unit design is simple, plumbing connections simple and clear,new balance sneakers, just after the installation of water system pressure test can be done.
auxiliary heat source

1, in the Hunan region due to relatively low temperature in winter, so if you need to increase when the auxiliary heating power, VRV can not install a secondary heating tool, except in the interior machine installation, if installation of the indoor unit when the auxiliary power, air conditioning,new balance shoes, electrical and mechanical auxiliary + + per room total load of household electricity consumption per household is likely to exceed the district's total electrical load into account.
1, for each household of the community into account the total power load of the last actual inspection,new new balance shoes, MAC unit in the water pipeline system, the auxiliary heat source using gas hot water boiler, gas hot water can not only provide hot water boilers, and low temperature as the auxiliary heat source in winter. Most important thing is do not bear the power load gas boiler, which will not exceed the total household electricity load.
maintenance, repair

1,new balance outlet, the indoor and outdoor unit with refrigerant pipe all connected, and through the end of pipe or fittings from the outdoor unit is allocated to the indoor unit, so if a leakage appeared unit, not only affects the use of all rooms (outdoor unit must be down for maintenance),为吃饭发愁的渭南人可以来看看 - Qzone日志, and the maintenance crew is exceptionally large, especially for indoor and outdoor connection pipe length and concealed, the inspection and maintenance of the project greater difficult to find fault and place, and R22 refrigerant leak will cause environmental pollution.
1, maintenance, maintenance is simple, if there is a failure within the machine will not affect the operation of the host, that does not affect the normal operation of the whole system.
operating costs

1, because the current standards adopted in China is 50Hz current,The feeling of love I do not regret - Qzone log, high frequency area for the VRV units is generally between 75-80Hz, rather than as propaganda, as in the range of 85 ~ 90Hz, therefore, although relative to the fixed speed compressor, it has a certain energy-saving effect of the relative, but the difference is not large (generally 5% ~ 10%, rather than the promotion of 30%).
1, MAC unit has a perfect 8-large, including water storage tanks, energy-saving advantages of its much larger than the VRV units, when the host at low load operation, the host needs to meet the Room load, the compressor off. Thus more energy efficient.
