Heat Pump EKO CLASSIC 155 working parameters for providing indoor climate of a cattle farm.
According to the World Energetic Committe prognoses the share of heat pumps will constitute 75% of total heat supply by 2020. The first heat pump manufactory in Estonia was started in August 2004, scheming to capture 25–30% of the Estonian and 10–15% of the Baltic market as a whole. Heat pumps have found application in many sectors of national economy, including milk farms. The present research work presents data about the work parameters of the heat pump Thermia ECO Classic 155 refrigerator, about the temperature of heating water and about farm indoor climate parameters.
In cattle farm the ground heat pump with underground circuit is used year-round (in winter for heating, in summer for cooling and at both seasons for heating water). In Estonian agriculture the particular heat pump is the first heat pump in cattle farm. Research of usage enables to investigate device’s function reliability, its suitability for providing indoor climate and satisfying technological needs.
The analysis of air climate parameters (temperature ϑ, relative humidity Ws, absolute humidity Wa, dew point ϑ t, velocity v, temperature of floor ϑ p, oxygen content O2, carbon dioxide content CO2, ammonia content NH3, radioactivity R, positive light air ions n+, negative light air ions n–, factor of unipolarity q, relative freshness of air V) measuring of the milk waiting area of the cattle farm and outdoor climate, are presented in the article.
Special and effective indices of the heat pump cooling system (boiling temperature of agent ϑ 0 , condensing temperature of agent ϑ k, compressor suction pressure P0, compressor compressive pressure Pk, weighty special cold productivity q0′ , compressor specific work l, condensator specific heat productivity q', refrigerant factor of cycle εi, heating factor of cycle εs, specific cubage of steam sucked in v1, bulk specific cold productivity qv, agent usage Ga, actual bulk capacity of compressor Vt, cold capacity of heat pump cooling device Q) are determined and calculated in the article. Circular processes of heat pump cooling system are shown in i-lgP diagram and specific and effective indices of heat pump EKO CLASSIC 155 are presented in.
