Abstract
The utility model relates to a cabinet type air conditioner (a fan coil) in the central air conditioner system which can accumulate cold in low temperature and store heat in high temperature. The utility model consists of a shell, an air inlet, a surface heat exchanger, a water condensation tray, a fan, an air outlet and an air adjustable inlet. One or more air adjustable inlets (the adjustable air can be the indoor returning air, outdoor fresh air or mixed air) are arranged in a shell which is positioned between the fan inlet and the surface heat exchanger. Through the adjustable valve, the adjustable air and low temperature (high temperature in winters) air of the surface heat exchanger are mixed in a certain proportion. After mixing, air temperature is increased in summers, while over high air temperature is lowered in winter, so as to achieve the aim that the fan sends wind after the low temperature (high temperature in winters) water sending general air conditioner sends temperature.
Description
Technical field
The utility model relates to floor air conditioner (fan coil), relates in particular to a kind of floor air conditioner that is used for low-temperature cold accumulation high-temperature heat accumulation central air conditioner system.
Background technology
Along with the enforcement that the electricity charge are valuated on time, this low ebb electricity price has only the pricing mode of 1/2～1/5 peak value electricity price, makes to adopt low-price electricity ice making in summer cold-storage, electric hot water accumulation of heat in winter night.The cold (heat) that air-conditioning employing on daytime or part employing store is eliminated refrigeration duty (thermic load) becomes very economic operation of air conditioner mode.
This low-temperature cold accumulation (high-temperature heat accumulation) is built by domestic the beginning.Owing to there are low temperature cold source so central air-conditioning great majority to adopt low-temperature cold accumulation, low temperature to send the air conditioning mode of water, cold air distribution.Minority adopts low-temperature cold accumulation, normal temperature air-conditioning to send the advantage of the air conditioning mode of water, the air-supply of normal temperature air-conditioning to be: chilled-water system and supply air system are less, and size, the room humidity that can reduce water and wind system equipment investment and energy consumption, saving construction and installation height, minimizing cabinet air-conditioner are lower.
Cold air distribution has also brought other some problems.A problem is the problem that cold air distribution is prone to the air outlet dewfall.The method that solves is a kind of to be that to adopt special-purpose low temperature induction air port, another kind be to adopt blending bin, will once blow fully to mix with room return air and blow after improving temperature.This will increase many equipment investments, simultaneously since induce or energy consumption that terminal blending bin blower fan is required with the saving of bucking-out system fan energy consumption; Two problems are that cold air distribution need increase the about 20mm of airduct insulation layer thickness and promptly increases height 40mm, add that cold air diffuser is more much higher than common air port, also offset the numerical value that the minimizing because of air output reduces the airduct size, middle-size and small-size airduct therefore commonly used adopts cold air distribution can not save the construction and installation height; Three problems are reductions of room humidity, and air enthalpy will increase, and human body and other hydrofuge amount also increase, and this all can increase the energy consumption of air-conditioning.Cross the discomfort that low humidity also can cause human body; To be the low humidity air-supply hour be prone to uneven air because of primary air flow reduces at air conditioner load for four problems, induces the air port employing level mostly vertical return air of blowing, and winter, high-temperature hot-air was difficult to send down, and cold wind is difficult to back come up.
Summary of the invention
The purpose of this utility model provides a kind ofly can realize that low temperature (high temperature in winter) supplies water, the floor air conditioner (fan coil) in the low-temperature cold accumulation high-temperature heat accumulation central air conditioner system of normal temperature air-conditioning air-supply.
The technical solution of the utility model is achieved in that the utility model has a casing that heat-insulation layer is thicker than conventional floor air conditioner, to guarantee not dewfall of casing appearance; One end of casing is an air inlet.The air cleaner that can extract out is equipped with at the air inlet place; Surface-type heat exchanger is contained in the side near air inlet.A connection low temperature (high temperature in winter) feed pipe, a return pipe pass casing and link to each other with the house steward of system on the surface-type heat exchanger.Surface-type heat exchanger is by being bolted in the casing; Be equipped with one below the surface-type heat exchanger and coagulate water pond, coagulate the water pond lower and be connected to an outlet pipe and pass casing and coagulate the supply mains with system and link to each other; The other end of casing is an air outlet, links to each other with the air outlet that is contained in the casing inner blower: it is characterized in that: have 1 and regulate wind inlet (regulate wind and can be indoor return air, outdoor new wind or it mixes wind) on the casing between the outlet of the inlet of blower fan and surface-type heat exchanger.Regulating the wind inlet can be in the side, bottom or top.Regulate on the wind inlet and be connected to the air cleaner that to extract out, be connected to air-valve behind the air cleaner.Mix with low temperature (winter high temperature) air of a certain proportion of adjusting wind by control valve with the surface-type heat exchanger outlet.Mix the thing air temperature raising in summer, then reduce too high air themperature winter, reaches to be blown by blower fan after low temperature (high temperature in winter) send water conventional air-conditioning wind pushing temperature again.
The utility model has the advantages that: 1. the cheap electric energy that has made full use of low-temperature cold accumulation and high-temperature heat accumulation; 2. adopt low temperature (high temperature in winter) thus send water to reduce pushing quantity and reduced the consumption of water system energy; 3. end surface formula heat exchanger increases because of heat transfer temperature difference, and the air quantity and the water yield reduce heat exchange area and reduced, and have reduced the cost of equipment of the surface-type heat exchanger that the heat exchanger price is the highest in the whole system; 4. the air port dewfall not owing to adopt the air-supply of normal temperature air-conditioning directly to blow, air humidity is moderate, reduces or also can balanced ventilation during winter at air conditioner load; 5. increase simultaneously engineering cost hardly, technology is implemented reliable.

The specific embodiment
Embodiment 1, and as shown in Figure 1, casing 4, one ends that the floor air conditioner (fan coil) in the low-temperature cold accumulation high-temperature heat accumulation central air conditioner system is made up of iron sheet, shape, insulation material etc. are air inlets 1; Surface-type heat exchanger 3 is contained in the side near air inlet 1; A connection low temperature (high temperature in winter) feed pipe, a return pipe pass casing 4 and link to each other with the house steward of system on the surface-type heat exchanger 3.Surface-type heat exchanger 3 is by being bolted in the casing 4; Be equipped with one below the surface-type heat exchanger 3 and coagulate water pond 2, lower is connected to an outlet pipe and passes casing 4 and coagulate the supply mains with system and link to each other; The other end of casing 4 is air outlets 7, links to each other with the air outlet of blower fan 6; Have one or several and regulate wind inlet 5 on the casing 4 between the outlet of the inlet of blower fan 6 and surface-type heat exchanger 3, regulating wind inlet 5 can be in the side, bottom or top.Mix with surface-type heat exchanger 3 outlet airs with a certain proportion of adjusting wind by regulating wind inlet 5, mixed air summer temp improves, then reduce too high air themperature winter, reaches to be blown by air outlet 7 by blower fan 6 after low temperature (high temperature in winter) send water conventional air-conditioning wind pushing temperature again.
