Abstract
The utility model discloses a domestic small central air conditioner which relates to the design and the manufacturing technology of a domestic central air conditioner. The utility model is composed of an indoor machine set and an outdoor machine set, wherein the indoor machine set is composed of a circulating water pump, a screw shell heat exchanger, an expansion water tank, a storage water tank, a blower and a main control system; the outdoor machine set is composed of two outdoor machines of a split air conditioner; two sets of inlet and outlet fluorine loops of the two outdoor machines of a split air conditioner are respectively connected to the screw shell heat exchanger with a set of water loops, which forms a screw shell heat exchanger with a single water double fluorine loop; the main control system is a programmable controller; the programmable controller sets the two outdoor machines not to simultaneously enter frost removing mode running; when one outdoor machine enters frost removing running, the other one must enter a heat pump running mode; the indoor machine set adopts the storage water tank and the screw shell heat exchanger with a single water double fluorine loop, so the indoor machine set can not blow cold wind in the frost removing running; the outdoor machine set is composed of the two outdoor machines of the split air conditioner, so the capacitance variation of the outdoor machine set is solves. The utility model has the advantages of reasonable double machine set running, balanced work and low energy consumption, so the life time of a compressor is prolonged.
Description
(1) technical field:
The utility model relates to the design and fabrication technology of civilian central air-conditioning.
(2) background technology:
Residential central air conditioner unit is a kind of energy-conservation, comfortable household small-size independence air-conditioning system.Mainly contain three kinds of forms such as wind pipe type system, cold/hot water unit and VRV system.The U.S. is based on the wind pipe type system, and Japan is based on the VRV system, and China is at present based on the cold/hot water unit, and output accounts for more than 70% of China's residential central air conditioner unit total amount.In recent years, area is on the increase above 100 square metres dwelling house, and residential central air conditioner unit can become the main flow of following air-conditioning consumption.Still be in the starting stage at China's small central air conditioning, average price is 250 yuan/square metre, the price height.Volume is big, and difficulty is installed, the operating cost height, and during defrosting, fan operation has cold wind to blow out, and can not adapt to the demand in market fully.
(3) summary of the invention:
The purpose of this utility model is at Defrost problem and unit transfiguration problem and a kind of residential central air conditioner unit that provides.
The technical solution of the utility model is: be made of indoor units and outdoor unit, indoor units is made of water circulating pump, screw shell heat-exhanger, expansion tank, accumulation of energy water tank, blower fan and master control system.Outdoor unit is made up of two split-type air conditioner off-premises stations.Two groups of turnover fluorine loops of two split-type air conditioner off-premises stations all are connected on the screw shell heat-exhanger with one group of water loop, constitute the two fluorine loops of single water screw shell heat-exhanger.Master control system is a Programmable Logic Controller, and Programmable Logic Controller is set two off-premises stations can not enter the defrosting mode operation simultaneously, and one enters Defrost operation, and another must enter the operation of heat pump pattern.
The beneficial effects of the utility model are: because indoor units adopts accumulation of energy water tank and the two fluorine loop heat exchangers of single water, so when Defrost operation, even the indoor fan operation can not go out cold wind yet, to the warm ripple disable influence in room conditioning zone, solved the problem of Defrost preferably.Outdoor unit is made up of two split-type air conditioner off-premises stations, the efficiency height adopts double-compressor can be adapted at moving under the single phase poaer supply condition, by the unit operation or the duplex running of double-compressor, make the air-conditioning system output quantity that adjustability preferably be arranged, solved unit transfiguration problem.The reasonable operation of two outdoor units, balance work cuts down the consumption of energy, and greatly prolongs the life-span of compressor.Save the time and the space of installing, stable performance can be satisfied the requirement of different user personalization.
(4) description of drawings:
Figure is the utility model structural representation.
(5) specific embodiment:
Residential central air conditioner unit is made of indoor units and outdoor unit as shown in the figure, and indoor units is made of water circulating pump 1, screw shell heat-exhanger 2, expansion tank 3, auxiliary thermal source 4, accumulation of energy water tank 5, blower fan and master control system.Outdoor unit is made up of two split-type air conditioner off-premises stations 6,7.Two groups of turnover fluorine loops 8,9 of two split-type air conditioner off-premises stations all are connected on the screw shell heat-exhanger 2 with one group of water loop 10, constitute the two fluorine loops of single water screw shell heat-exhanger.Master control system is a Programmable Logic Controller, and Programmable Logic Controller is set two off-premises stations can not enter the defrosting mode operation simultaneously, and one enters Defrost operation, and another must enter the operation of heat pump pattern.Auxiliary thermal source adopts gas furnace or electrothermal furnace, and the accumulation of energy water tank is the positive displacement electric heater.Unit is selected the household electrical appliances accessory in a large number for use, under the prerequisite that guarantees unit performance, and the cost that has greatly reduced exploitation and made, price is low, and performance is good.Refrigerating capacity is 5～28KW, and construction area is 50～300 square metres, and off-premises station is made up of two 1Hp, 1.5Hp, 2Hp, 2.5Hp, 3Hp, 5Hp family expenses split-type air conditioner off-premises station respectively.Indoor set is cabinet-type and wall-hanging.
