Abstract

The utility model discloses an integral water resource air conditioner with a heat pump, which consists of a housing, an air inlet and an air outlet, and a blower and a heat pump system arranged in the housing; the heat pump system comprises a compressor, wherein the gas outlet of the compressor is communicated with a valve port of a four-way reserving valve through a pressure switch; a second valve port of the four-way reserving valve is communicated with a third valve port of four-way reserving valve through a finned heat exchanger, a heat expansion valve and a double-pipe heat exchanger; afourth valve port of the four-way reserving valve is communicated with a gas suction inlet of the compressor through the pressure switch and a suction filter; one orifice of the outer pipe of the double-pipe heat exchanger is communicated with a cooling water feed pipe, and the other orifice is communicated with a cooling water return pipe; temperature sensors are arranged on the cooling water feed pipe and on the return pipe. By adopting the integral structure, the utility model has the advantages of compact structure and attractive appearance, thereby avoiding problems such as weakening of cooling and heating capabilities, fluorine leakage from the pipeline port, mounting space occupied by outdoor unit, etc.

Description

The monoblock type water source heat pump air-conditioner

Technical field

The utility model relates to air-conditioning, especially relates to the monoblock type water source heat pump air-conditioner.

Background technology

The air-conditioning that is used for large tracts of land places of business such as large supermarket, automobile exhibition room, station, factory floor, hall, restaurant and production place at present mostly is split-type wind-cooled cabinet-type air conditioner air-conditioning, not only cooling or heating effect is poor for it, and energy consumption is big, and the heat that the while condenser gives out has also quickened zone " tropical island effect ".Because depth distance in large-scale place of business is long, indoor set and off-premises station are at a distance of too far away, long fluorine connecting pipe line makes unit increase towards the fluorine amount, and it is slow to freeze, heat speed, thereby line pressure falls and increases the increase and the shortening in compressor life-span that causes energy consumption.

The utility model content

The utility model purpose is to provide a kind of high energy efficiency, low noise, monoblock type water source heat pump air-conditioner cheaply.

For achieving the above object, the utility model can be taked following technical proposals:

Monoblock type water source heat pump air-conditioner described in the utility model, it is by casing, is opened in constituting into and out of air port and the blower fan, the water source heat pump units that are arranged in the casing on the described casing; Described water source heat pump units comprises compressor, and described compressor outlet is connected with a valve port of four-way change-over valve by pressure switch; Second valve port of described four-way change-over valve is connected with the 3rd valve port of four-way change-over valve by pipe in finned heat exchanger, heating power expansion valve, the double pipe heat exchanger; The 4th valve port of four-way change-over valve is connected with the compressor air suction mouth by pressure switch, air-breathing filter; One mouth of pipe of described double pipe heat exchanger outer tube is connected with cooling water supply pipe, and its another mouth of pipe is connected with CWR; Described cooling water supply pipe, CWR are provided with temperature sensor.

Described compressor is two scroll compressors that alternately opened and closed by microcomputer controller control.

The utility model advantage is to take monolithic construction, makes compact conformation, and is aesthetic in appearance, and avoided that long cold and hot ability decay, the pipe interface that causes of the connecting line that split-type structural caused leaks fluorine, off-premises station takies problems such as installing space.Replace the compressor that opens and closes with two same models, under the control of microcomputer controller, what of cold and hot amount demand to regulate the firing platform number and the number of times of compressor automatically according to by the balance abrasion principle, can realize that energy regulates automatically, avoid the frequent starting of compressor, reduced energy consumption, more energy-conservation than frequency changer.Utilize low-grade energy (source, water source),, make it reach energy-conservation order ground by utilizing the low-grade energy of surface layer and rivers and lakes steady state.Energy source when constant source, ground or water source have guaranteed the heat pump duty, thus make it continuously energy be supplied with the user, be not subjected to the weather condition effect.Absorb during operation of heat pump be the source, ground can or the water source energy, unit does not need defrost, compares with wind regime type heat pump, has avoided the process of defrost repeatedly in winter, has not only improved heat capacity, and has reduced the fault rate of compressor.Owing to adopt tube-in-tube condenser, compare with board-like and shell and tube exchanger, not only reduced the possibility of system jams, also possessed the good antiscale property function simultaneously.
