The compressor is arranged in a comparatively closed casing and an outer casing of the compressor is covered by a flexible sound-absorbing material and the cover is fastened by a loop, and the flexible sound-absorbing material is adhered to an inner surface of the casing. The noise-eliminating air-returning box is arranged to an air-returning mouth of the air conditioner, and the box body is formed by a galvanized board and an inner deadening liner, and the sound-absorbing material is used as an inner liner of an inner wall of the air-returning box. A fresh air intake is arranged on a side of the noise-eliminating air- returning box. The noise can be absorbed by soft sponge, etc. sound absorbing materials so as to reduce the noise of the whole air conditioner. Moreover, the noise-eliminating air-returning box is arranged at the air-returning mouth of the air conditioner and the sound-absorbing materials is added to the inner wall, thus reaching an aim of absorbing the noise in the air conditioner and the noise of air-returning pipelines and also result in an equal air flow to lead to a smooth air feeding and returning in the air conditioner.

Description

Pump type heat changes in temperature water-cooled air conditioner

Technical field

The utility model relates to a kind of water-cooled air conditioner, and particularly a kind of pump type heat changes in temperature water-cooled air conditioner belongs to International Classification of Patents " F24F " conditioner technical field.

Background technology

Air-conditioner generally is made up of condenser, compressor, evaporimeter and electric part, and cold-producing medium working medium heats in condenser (radiator), and heat is passed to outdoor air.Absorption refrigeration in evaporimeter.In summer, the radiator of general condenser be by blower fan to the forced convertion of condenser ambient air, rely on the air heat radiation, but weak effect.

Water-cooled air conditioner is made up of condenser, compressor, evaporimeter, blower fan and electric part, and its condenser is a water collar tubular type condenser, the diameter difference, and the condenser that is nested connects cooling water and cold-producing medium working medium respectively.Two carriers carry out heat exchange in condenser, cooling water flows in cooling water pipe, and the heat that cold-producing medium the distributes water that is cooled is taken away.

This design is on the basis of former window air conditioner, changes air cooled condenser into the water-cooled double-pipe condenser, and it is simple in structure, good thermal conduction.Adopt cooling water dual circuit system, Inlet and outlet water is walked heat through cooling tower and water pump tape loop, and condensed water also can be concentrated discharge.But above-mentioned design runs into following several problem in practice and installing.

Water-cooled air conditioner is a single cold type, is not pump type heat;

Water-cooled air conditioner is placed (so installation usually) on the furred ceiling, to indoor air-supply down or side air-supply, make noise problem highlight through airduct;

The new wind of indoor needs, fresh wind tube is connected the problem of having with this air-conditioner.

The problems referred to above have had influence on the quality of water-cooled air conditioner in using or installing.

Summary of the invention

The purpose of this utility model provides a kind of modified one pump type heat changes in temperature water-cooled air conditioner of water-cooled air conditioner, to reduce noise, improves the quality of air-conditioner, increases winter heating's function, improves the air current composition of air-conditioner.

The utility model is by the following technical solutions:

Pump type heat changes in temperature water-cooled air conditioner, comprise condenser (1), compressor (3), evaporimeter (2), four-way change-over valve (4), noise reduction air-intaking box (5), blower fan (6) and electric part (16), compressor (3) is placed in the housing (15) of relative closure, wrap up with the housing parts of sound-absorbing soft material (9), and tighten with clip with compressor; Sound-absorbing soft material (8) is attached to the inner surface of housing (15), and is bonding with special glue.

Add noise reduction air-intaking box (5) at the return air inlet place of air-conditioner, be connected in air-conditioner with screw (13), form casing, its air-intaking box inwall sound absorbent of inner liner (10) by galvanized sheet (11) and liner acoustic material (10) by flange; The side of noise reduction air-intaking box (5) has circular or square new wind to introduce hole (12).

Compressor reduces housing sound absorbent of inner liner (8) that noise uses can be adopted Japanese senior convex-concave compartment layer or adopt sound-absorbing soft material such as soft sponge; The sound-absorbing material of air-intaking box inwall (10) adopts sound-absorbing materials such as soft sponge or U.S. OWENS CORNING lined efficient centrifugal cotton.

This design of the present utility model, make air-conditioner summer by cold-producing medium working medium absorption refrigeration in evaporimeter, the cold-producing medium in the condenser is passed to water with heat, water is through the heat radiation of cooling tower and water pump.In the winter time, through four-way change-over valve, cold-producing medium absorbs the heat in the water in condenser, and cold-producing medium is passed to indoor in the evaporimeter heat release, reach the purpose of heating.Like this, both energy savings helped environment again.

This air-conditioner because water cooked the secondary media and directly do not dispel the heat by outdoor air, thereby is to be placed in the indoor furred ceiling in using practice, there is not an off-premises station outdoor, corresponding increase noise of meeting and vibration, simultaneously, noise superposes in furred ceiling can produce the secondary noise again.By adopting concavo-convex compartment layer at shell inner surface and compressor case or adopting sound-absorbing material such as soft sponge, absorb noise, thereby reduce the overall noise of air-conditioner.In addition, design increases the noise reduction air-intaking box at air-conditioner return air inlet place, its inwall adopts sound-absorbing materials such as soft sponge or U.S. OWENS CORNING lined efficient centrifugal cotton, can play the purpose that absorbs noise in interior noise of air-conditioner and the return air duct, can also play the air-flow proportionality action, make air-conditioner air entering and returning air-flow happy.Whole air-intaking box is compact to design, easy accessibility.The new wind of its side is introduced the hole and new wind directly can be introduced, and after mixing in air-intaking box, drains into indoor through surface cooler (evaporimeter).Like this, can reduce the air-conditioning initial cost of whole building, make and install simply, compact conformation can reduce because the noise that the wind turbulent flow generates.

The specific embodiment

As shown in Figure 2: compressor is placed in the housing 15 of relative closure, compressor case is partly wrapped up, tighten with clip with sound-absorbing soft material 9; In shell inner surface, the senior concavo-convex compartment layer of liner Japan or adopt sound-absorbing soft material 8 such as soft sponge is attached to shell inner surface, and bonding with special glue.

Shown in Fig. 3,4: design increases noise reduction air-intaking box 5 at water-cooled air conditioner return air inlet place, adopts galvanized sheet 11 structures, has certain rigid, and its air-intaking box inwall adopts sound-absorbing materials such as sponge or U.S. OWENS CORNING lined efficient centrifugal cotton.

As shown in Figure 5: the noise reduction air-intaking box is installed in the return air inlet place of air-conditioner, and is connected with screw 13 by flange between the air-conditioner.When air-conditioning needed repairing, air-intaking box was pulled down at 17 places at flange, the noise reduction air-intaking box was installed after the maintenance again, screw down to get final product, thus easy to maintenance.

Again referring to accompanying drawing 3,4: the new wind of lateral layout at the noise reduction air-intaking box is introduced hole 12, for circular or square, is preformed hole, needs the time spent to open, and when not required, it and air-intaking box are one.New wind directly can be introduced air-intaking box by it.If building air-conditioner is provided with new wind, can use this hole, new wind is introduced, in air-intaking box, mix, drain into indoor through evaporimeter.Can reduce because the noise that the wind turbulent flow generates.
