Abstract

The utility model relates to a combining type air conditioner set of the existing air-blowing-returning machine model. Because a fresh air regulating valve, an air exhaust valve, and a filter are very close, high-speed air molecular flow which is accelerated by an impeller wheel of an air returning fan is easy to cause positive value static pressure around the fresh air regulating valve and the air exhaust valve; when air returning quantity is slightly large, fresh air can not enter a system from a fresh air inlet. The fresh air regulating valve and an air returning valve are all arranged at the suction end of a booster fan so as to enable the utility model to operate according to the requirement of air conditioning design, and guarantee that an air conditioning area can save energy by using returning air in the maximal limitation under the condition of the necessary fresh air.

Description

Mixed-air boosted type assembled air-conditioner unit

It is bigger that the utility model relates to a kind of SR, particularly the bigger two blower fan assembled air-conditioner units of filter resistance.

Existing pair of blower fan assembled air-conditioner unit, all for give, return air type unit, its structure all is after exhaustion section, mixed wind section, fillter section are located at the return fan section successively, and, establish trickle section, surface cooling section, bringing-up section, humidifier section, blower section, noise reduction section, inferior high efficiency filter section etc. respectively thereafter according to the needs of design of air conditioning.This unit is because exhaust valve, new air-valve, filter three parts are separated by too closely, and this special flowing resistance element of filter has bigger barrier effect because of the air molecule stream to high-speed motion, in its front and back bigger differential static pressure arranged.Air molecule stream after being quickened by the return fan impeller is easy to form on the occasion of static pressure to the last band of filter at the return fan air outlet, the static pressure at this stylish air-valve place also be on the occasion of.Therefore unit will be by the designing requirement of air-conditioning under the condition of this permutation and combination, protect card Amount decide to regulate under the condition of air output by unit newly, the ratio of return air, no matter be give, in the design selection of return fan, still all very difficult in the practical adjustments operation.When the return air amount in the unit was big, the static pressure at new air-valve place was not variable negative, causes new wind not only can not enter system from fresh wind port, will have return air to discharge from fresh wind port on the contrary.The air quantity that the air quantity of return fan processing is at this moment obviously handled greater than pressure fan, blow zones is in negative pressure, and Air-conditioner design requires blow zones to be in malleation.Want novel wind energy and enter system from fresh wind port, air returning valve in the middle of must turning down is opened exhaust valve.When novel wind energy entered system, it was too little the return air amount to occur, caused the air output deficiency.This shows, send, return air type unit can not be by Air-conditioner design requirement operation, unit can not be operated in guarantee under the new wind condition that conditioned area is necessary that it is energy-conservation to maximally utilise return air.The 37th page of the 5th phase of " HVAC " magazine in 1998 also spoken of in the reality test ubiquity and these problems.

For addressing this problem, mention existing solution in " HVAC " magazine and be pressure fan and return fan thrown off and arrange, adopts parallel or vertically superposed arrangement form, with newly, time, exhaust duct and air-valve connect outside machine.This mode can only improve give, problem that return air type unit is existing, but to increase the area of Air Conditioning Facilities.

The purpose of this utility model provides the mixed-air boosted type assembled air-conditioner unit after a kind of the improvement; it can make unit under the condition of specified air output; regulate ratio effectively by new, the return air of unit, guarantee unit can be preferably by the requirement operation of Air-conditioner design.Make conditioned area meet under the sanitary condition energy-conservation to greatest extent.

The purpose of this utility model is achieved in that cancellation existing is sent, mixed wind section, exhaustion section, the return fan section of return air type unit fillter section front, fillter section is extended back pullout (BPO) so that maintenance, and before a fillter section is arranged, establish and mix wind supercharging section, be about to mixed wind section and booster fan section and unite two into one; Perhaps cancel exhaustion section and return fan section, behind its fillter section, establish the booster fan section.More than two kinds of permutation and combination methods all make newly, air returning valve is positioned at booster fan suction side, static pressure new, the air returning valve place is negative value, regulates new, air returning ratio and is easier to.Behind the cancellation exhaustion section, in the time of can designing in system, look field condition and establish exhaust valve at the backwind tube place that tries one's best away from booster fan.For closed air-conditioning system, if reasonably regulate new, return, exhaust valve, the static pressure at exhaust valve place can be on the occasion of, regulate new, return, air draft is more convenient; For the more open system in door and window slit, when needs utilize return air energy-conservation in a large number, the static pressure at the exhaust valve place in the backwind tube differ be decided to be on the occasion of, this moment can not be by opening the exhaust valve air draft, but can utilize indoor malleation natural exhaust, during with brand-new wind, can close air returning valve at transition season, open the exhaust valve air draft.Needn't consider air draft when therefore unit designs.

The utility model changes because of a permutation and combination method to former unit, so structure is simple especially; And can make suction side new, that the return air control valve all is positioned at booster fan, thus can by Air-conditioner design requirements regulate by unit newly, the return air amount, make conditioned area under the condition that essential new wind is arranged, it is energy-conservation to maximally utilise return air.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof:

The permutation and combination method and the working condition of concrete unit of the present utility model are described below in conjunction with Fig. 1 and Fig. 2:

In Fig. 1, the air returning valve 1 of this unit and new air-valve 2 are directly arranged in the booster fan section 5, even mixing wind section 4 and booster fan section 5 unites two into one, what be arranged in order thereafter is that a fillter section 6, trickle section 7, surface cooling section 8, bringing-up section 9, humidifier section 10, blower section 11 are arranged, and will select some air conditioning function sections or increase some other functional section again in above functional section according to the requirement of concrete Air-conditioner design usually.

After unit and air-conditioning system are connected, regulate air returning valve 1, new air-valve 2 and exhaust valve (not drawing among the figure) to suitable position, new, return air is by the ratio mixing of Air-conditioner design requirements, is sent to conditioned area again after unit is handled the temperature of being scheduled to, humidity.

In Fig. 2, mixed wind section 4 and booster fan section 5 in the unit separate, and establish fillter section 6 in their centres, and other functional section of unit and regulative mode are all with the unit of Fig. 1.

More than the mixed-air boosted type unit of two kinds of permutation and combination, obviously unit the best of representing of Fig. 1.
