Abstract

The utility model relates to a domestic combined air-conditioner which is provided with a compressor, an evaporator, a condenser, a reverse valve, a blower, etc. The domestic combined air-conditioner adopts a liquid storage choke which has a two-way throttling action to replace an ordinary throttle valve. A set of indoor and outdoor machine groups (a single compressor, a single evaporator) are simultaneously used to send wind (cool wind and warm wind) to a plurality of rooms. The indoor machine group is composed of the evaporator, the blower, an air outlet, a controller, etc. The other components compose the outdoor machine group. The new designed liquid storage choke has large volume and is matched with two throttle valves and a one-way valve to guarantee optimal throttling condition when the machine groups conduct refrigeration and heating, and to release the working medium leakage. Compared with the ordinary domestic air-conditioner, the domestic combined air-conditioner has less noise, low cost, stable operation, etc. The utility model has 1.15KW H power consumption and can be used for the house with three rooms and a hall (about 40 m < 2 >).

Description

Family expenses assembly air-conditioning

The utility model belongs to minitype air conditioner equipment.

At present domestic air conditioning has 3 kinds of forms basically: 1. window formula; 2. chorista formula; 3. one hold in the palm two (three) formulas.Wall-through type air conditioner is a monomer structure, volume compact, and cost is low, but owing to the installation site of compressor can not change, so noise is bigger; Can only be installed in addition on the window, daylighting is had certain influence; The chorista formula is that indoor and outdoor two big assemblies constitute, and the installation site is reasonable than window air conditioner, and noise is little, but its cost height, cold-producing medium is easily revealed, and makes fluctuation of service.These two kinds of air-conditionings are single compressed machine and evaporimeter, can only be applicable to single room air conditioner.One holder, two (three) formulas are outdoor monomer, and indoor multiple hull construction has more than two and evaporates unit, can blow simultaneously to two (three) rooms, but its complex structure, assembly is more, by the long cost height in mouthful multitube road, unit operation is unreasonable, and the leakage of refrigerant problem is even more serious.

The purpose of this utility model provides a kind of family expenses combined type air-conditioning, is characterized in can sending hot and cold wind to a plurality of rooms simultaneously with a cover unit.System is furnished with the liquid storage flow controller of big volume, working medium is revealed greatly alleviated, and is stable, plants domestic air conditioning relatively with first three, and it has characteristics such as noise is little, simple in structure, and cost is low.

Accompanying drawing 1 is a theory diagram of the present utility model, and accompanying drawing 2 is the structure principle chart of liquid storage flow controller, and accompanying drawing 3 is a floor plan of the present utility model.Family expenses assembly air-conditioning has compressor (1), evaporimeter (2), condenser (3), reversal valve (4), air outlet (6), blower fan (16) and adopts the liquid storage flow controller (5) with bidirectional throttle effect, substitutes the choke valve in the common kind of refrigeration cycle.Constitute outdoor unit by compressor (1), condenser (3), reversal valve (4) and liquid storage flow controller (5).Constitute indoor units by evaporimeter (2), air outlet (6), blower fan (16), controller (7), adopt a cover indoor and outdoor unit (single compressor, single evaporator) to send (hot and cold) wind to a plurality of rooms simultaneously.Family expenses assembly air conditioner refrigerating circulation process is: cold-producing medium is finished refrigeration in evaporimeter (2) after, low pressure steam state working medium is returned compressor (1) through reversal valve (4), be high-pressure liquid through reversal valve (4) to condenser (3) cooling again after the compression, enter in the evaporimeter (2) through liquid storage flow controller (5) and finish circulation.Be used to heat as system, then change the reversal valve trend, the gases at high pressure that compressor (1) is discharged are introduced into former evaporimeter (2) through reversal valve (4), and heat release is condensed after liquid storage flow controller (5) enters former condenser (3) evaporation, and the gas after the evaporation returns compressor (1) through reversal valve (4).

Accompanying drawing 2 is the structure principle chart of liquid storage flow controller.Common kind of refrigeration cycle or heat pump type refrigerating unit only are provided with a choke valve, and throttle valve adjustment can only be yielded to low operating mode operation or readjust choke valve at best cooling condition during refrigeration.Newly-designed liquid storage flow controller (5) mixes two choke valves (9,10) by the container (8) of a sealing and two check valves (11,12) are welded, and the skirt of four valve bodies all is dipped in the refrigerating fluid.Choke valve (9) is adjusted to the best open degree of refrigeration throttling, and choke valve (10) is adjusted to the best open degree that heats throttling.When cooling condition, check valve (11) is closed automatically, and check valve (12) is opened and the common feed liquor of choke valve (10) automatically, choke valve (9) beginning throttling; When heating condition, check valve (11) is opened and the common feed liquor of choke valve (9) automatically, and check valve (12) is closed automatically, choke valve (10) beginning throttling.So liquid storage flow controller (5) has the bidirectional throttle effect, when so setting can guarantee the unit cooling and warming, be best cutting condition.

The horizontal layout of family expenses assembly air-conditioning as shown in Figure 3.The cold-producing medium evaporation of absorbing heat in evaporimeter (2) is delivered to the air outlet (6) at each room place with cold (heat) wind by the volume damper (17) at each wind passage mouth place through blower fan (16), enters each air-conditioned room.Each room temperature is set and is implemented control automatically by the controller (7) of indoor units.Controller (7) is by single-chip microcomputer (13), temperature sensor (14), and thermoregulator (15) and corresponding circuit are formed.Single-chip microcomputer (13) adopts 98 type single-chip microcomputers that each air-conditioned room is implemented whole control, and indoor temperature reaches controller (7) by temperature sensor (14).Control is divided into two kinds of situations: at first regulate the open degree of volume damper (17) by transmission device, (this valve also can be regulated respectively) changes air output.Not obvious as the temperature reduction, then unit keeps the full-load operation state.Amount is excessive if temperature descends refrigeration (heat), then regulates the rotating speed of compressor (1) by controller (7), to guarantee suitable refrigeration (heat) amount, reaches energy-conservation effect.

Specific embodiments of the present utility model can be selected semi-enclosed air cooling refrigeration Condensing units one cover of B24F28 type for use.Input power is 1.1KW, and rating under air conditioning condition is 3500kcal/h.Install liquid storage flow controller (5) additional, and reversal valve (4).Evaporimeter (2) is indoor ceiling mounting type.Evaporator area is 4-5m ², the air quantity of blower fan (16) is 500m ³/ h, power are 60W.Air supply duct is the gentle type insulation ajutage of φ 150.Air outlet is the double-deck blinds air door of 200 * 250mm air port, can regulate wind direction.Outdoor unit is positioned at platform courtyard or outdoor suitable ventilation, and the copper pipe by 16 millimeters of Φ 10～Φ is connected with indoor units.The whole power consumption of assembly air-conditioning unit is 1.15kw, can (living space is about 40m for the use of three living rooms and one sitting room dwelling house ²), the summer air-conditioning temperature is about 27 ℃, and relative temperature is less than 60%; When winter, outdoor temperature was not less than 5 ℃, indoor temperature can reach about 20 ℃.Plant domestic air conditioning relatively with first three, identical refrigeration area can economize on electricity more than 1/3, and noise is little, moves reasonably stability, and can adapt to the room of dissimilar structures.
